Features
- Accommodates Super Micro, Micro, or Macro Cuvettes
- Compatible with 12.5 mm x 12.5 mm x 45 mm Cuvettes with a Z-Dimension (Beam Height) of 8.5 mm
- SM1 (1.035"-40) and 30 mm Cage Compatible
- Post Mountable via 1/4"-20 (M6) Tap
- Light-Tight Cover Available
Designed to accommodate standard micro and macro cuvettes, the CVH100 Cuvette Holder can be used in fiber or free-space applications. The holder is compatible with 12.5 mm x 12.5 mm x 45 mm (0.49" x 0.49" x 1.77") cuvettes and features four SM1-compatible (1.035"-40) light ports, thereby offering two perpendicular light paths for transmission and fluorescence measurements. Both optical axes (blue lines in the photo to the right) and the axis for the post mount (red in the photo to the right) have a common crossing intersection point, which allows the user to turn the holder to use another port while maintaining the alignment to the optical axes in free space applications.
When purchasing small volume or window cuvettes, a 'Z' dimension is often specified. This 'Z' dimension is the length from the bottom of the cuvette to the center of the sample chamber window on the cuvette. The CVH100 and the included fiber adapter are designed such that the beam height will be 8.5 mm above the bottom of the cuvette (see the Specs tab for a diagram).
Filter Holder
The CVH100 cuvette holder includes one CVH100-FH filter holder, which is designed to house Ø1" mounted filters measuring up to 7 mm in thickness. These filters are typically used to achieve wavelength isolation for incident or emitted radiation. The filter holder is located between the cuvette and one of the ports. Additional CVH100-FH filter holders can be ordered separately, thereby enabling quick exchange of filters.
Fiber Adapter
The holder is shipped with a collimating SMA-to-SM1 fiber adapter, allowing the cuvette holder to be directly connected to fiber-based light sources, detectors, or spectrometers. We recommend our multimode patch cables for interconnection. An uncoated B270 collimating optic is included. Two SM1-threaded end caps are also included so that unused ports can be covered to prevent dust from entering the optomechanical assembly.
Ports of the Cuvette Holder
Input light port with 9 mm x 14 mm slotted hole
Output light port with Ø12 mm round hole
Ports of the 2nd optical axis with Ø9 mm round hole
Light-Tight Cover
A light-tight cover for the cuvette holder is available for applications that are particularly sensitive to light. This cover is compatible with cuvettes up to 50 mm (1.96") tall, including the stopper, as well as with the filter holder included with the cuvette holder.
Mounting
All four access ports on the cuvette holder are equipped with four 4-40 taps for compatibility with our 30 mm cage systems and a single bore that has internal SM1 (1.035"-40) threading for direct mounting to our lens tubes or other SM1-compatible products such as our OSL2 white light source or our mounted high-power LEDs. The CVH100 can be post mounted using the 1/4"-20 (M6) mounting hole on the bottom of the cuvette holder. The black anodized aluminum coating protects the mount from corrosion in typical lab environments.
Cuvettes
Thorlabs offers a selection of UV fused quartz cuvettes for use with our cuvette holder. These high-quality cuvettes transmit light down to 200 nm and are available in macro, micro, and super micro sizes for 3500 µL, 1400 µL, 700 µL, and 100 µL samples. They are available in versions with two polished windows for absorption spectroscopy or four polished windows for fluorescence spectroscopy where the measurement of the signal is at right angles to the beam path.

(posted 2022-04-07 11:28:13.74) I would like to know if the CVH100-COL can be used in combination with cage plates, either CP33 or CP8T. Thanks mdiekmann
(posted 2022-04-08 07:19:04.0) Yes, this is possible. The external SM1 thread can be connected directly to the internal SM1 thread on the cage plates. les.tack
(posted 2018-05-17 18:29:57.99) Are any of the 4 port cuvette products offered with FC/PC input? This would be for my light source. YLohia
(posted 2018-08-01 04:24:03.0) Thank you for your inquiry. At the moment we can only offer the included collimator with SMA connector. You could connect a SM1FC fiber adapter directly to one of the cuvette holder ports. Alternatively, a custom collimator could be build using a fiber adapter, lens tube and plano-convex lens. In addition, the included collimator could be used with a FC/PC to SMA hybrid patch cable. https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=5016 t.ding
(posted 2017-08-08 22:35:59.21) If you can make it temperature controllable, I would rate it very useful. Is it possible if you can provide such a product? I think it be even more popular as it provides online monitoring of chemistry process where temperature control and stiring takes place. mdiekmann
(posted 2017-08-16 09:55:16.0) This is a response from Meike at Thorlabs: Thank you for your feedback! We might consider to release a temperature controlled version in the future, so we would be interested to learn more about your application. I will contact you directly to discuss this further. messinat
(posted 2017-04-06 10:44:57.193) I have a single photon counting module with an FC/APC fiber. Is it possible to get a CVH100-COL made with this fiber connection rather than SMA?
Thanks,
Troy swick
(posted 2017-04-10 03:30:34.0) This is a response from Sebastian at Thorlabs. Thank you for the inquiry.
At the time we do not offer CVH100-COL with FC/APC adapter. For using FC/APC fiber patch cables with cuvette holder CVH100 our standard collimators for FC/APC would be suitable. One of the ports with SM1 thread can be used for mounting. I will contact you directly for assistance. jaime.de.sousa
(posted 2015-09-11 10:37:45.69) Dear Throlabs team, I´m looking to set up an application using this cuvette holder CH. I have a 980 nm laser which ends at standard SMA conexion fiber with 0,22 NA , I want to connect it to the CH, and in 90 degrees measure fluorescence. I want a filter in the signal exit low pass 900 or 950nm to ensure source light does not reaches detector. Also, I want to collimate light both at entrance and exit to ensure optimal excitation and maximum signal. Last, I need a base to hold the system. I though on the following configuration but I need your help on this:
CVH-100/M
2x CVH100-COL
2x LA 1074
2x SM1CP2M (I believe system comes with two by default)
CVH100-FH (is it included in CH?)
FESH0950 and or FESH0750 (stil have to verify, but are those compatible?)
TR4
PH40/M
BA1/M
And last one optic fibers, round to slit since slit is the enter of spectrometer BFL200HS02
Will really appreciate your feedback.
Best Regards, shallwig

(posted 2012-07-02 11:32:00.0) A response from Julien at Thorlabs: Thank you for your positive feedback! We are more than happy to have been able to provide you with a product that can reduce the effort required to perform your measurement. This is what we strive for! cbrideau
(posted 2012-06-29 20:33:15.0) I just wanted to say how happy our lab has been with this product. We use it frequently for fluorescent dye characterization. The flexibility of the 4 ports has been a big help for coupling different light sources into the cube. Also, I've bought quite a few of those spare filter holders and they are proving very convenient! bdada

Thank you so much for your feedback! We will definitely keep it in mind as we continue expanding our product line of Microscopy products. mmancini
(posted 2011-10-05 15:37:03.0) I love this product and have recommended it to several people already. It's compact, flexible to meet my changing experimental needs, integrates wonderfully with my other optical components, and looks and acts more expensive than it sells for. Bravo. jjurado
(posted 2011-07-18 11:03:00.0) Response from Javier at Thorlabs to damien.decourten: Thank you very much for contacting us. For this application, it may be recommendable to use an achromatic doublet lens to increase the collection efficiency, and to achieve a tighter focus spot onto the active area of the photodiode. The CVH100 features four SM1-threaded light ports, to which you can couple a lens tube for housing the lens, and an adapter for the photodiode. I will contact you directly to discuss the details of your application.

(posted 2011-07-13 15:03:37.0) Hi,
I bought this device that works great. But I need now to implement it with very low light intensity. I would like to use this device directly with a (preamplified) photodiode for 90° fluoreseence measurements. What are your recommandations using a colimating lens before the photodiode for collecting as much emitted light as possible and a cage system/lens tube for holding everything together? Thanks jjurado
(posted 2011-03-29 17:43:00.0) Response from Javier at Thorlabs to cbrideau: Thank you very much for your feedback. We can certainly offer additional filter cartridges for this cuvette holder. I will contact you directly with a quotation. cbrideau
(posted 2011-03-29 14:41:42.0) I bought this device and it is working out quite well. Would I be able to get additional filter cartridges? The 1" filter holder works quite well, but when I need to change filters I would prefer to have them pre-mounted in additional cartridges. Can you offer the 1" filter holder as a separate item so I can buy more? bdada
(posted 2011-03-08 12:06:00.0) Response from Buki:
Thank you for your feedback. The CCS series of USB spectrometers come with an SMA connectorized fiber that can be connected to the CVH100 cuvette holder via an SMA to SM1 fiber adapter included with the CVH100. Alternatively, you can connect the SMA connectorized fiber to the CVH100-COL, an SMA to SM1 adapter that lets you mount a lens of your choice. More information is available in the Overview section of this page: http://www.thorlabs.com/NewGroupPage9.cfm?ObjectGroup_ID=4982.
Please contact TechSupport@thorlabs.com with additional questions you may have. lmorgus

(posted 2011-03-07 11:23:02.0) How can the CVH100 be used with the USB spetrometer?
Thanks! Thorlabs
(posted 2010-07-30 13:54:35.0) Response from Javier at Thorlabs to jhsu: Thank you for your feedback. We currently do not offer an FC version of the CVH100-COL. I will discus the development of this product with our design engineers, and keep you informed of the status. jhsu
(posted 2010-07-29 23:59:50.0) Dear Thorlabs:

- For Free-Space and Fiber Applications
- One Filter Holder for Mounted Ø1" Filters Included (Additional Filter Holders Available Separately)
- Interchangeable SMA Collimator Included
- Multiple Mounting Options
The CVH100 Cuvette Holder, which includes an interchangeable SMA Fiber Adapter and one CVH100-FH Filter Holder, offers a compact means for performing spectroscopic measurements. Designed to hold 12.5 mm x 12.5 mm x 45 mm cuvettes with a "Z" dimension of 8.5 mm (see the Specs tab), this cuvette holder provides four SM1-compatible (1.035"-40) side light ports for use with our SM1 Lens Tube products, facilitating light-tight applications when paired with the cover sold below. For quick filter exchanges, additional Ø1" filter holders (Item # CVH100-FH) are available separately.
The cuvette holder includes a fiber adapter designed to collimate the output from an SMA-terminated fiber with a fixed, non-removable, uncoated B270 collimating optic (f=8 mm, NA=0.547). For applications requiring a different lens, the fiber adapter can be replaced by the optional CVH100-COL fiber adapter (available below), which can mount any unmounted Ø1/2", plano-convex collimating lens.

Lens is Not Included with the CVH100-COL
- SMA905-to-SM1 Fiber Adapter for the CVH100(/M) Cuvette Holder
- Internal SM05 (0.535"-40) Threads for Mounting a Ø1/2" Plano-Convex Lens Into the Beam Path
- External SM1 (1.035"-40) Threads Compatible with Side Ports on CVH100(/M)
- Includes 6.8 mm and 9.6 mm Long Spacer Rings and a SM05RR Retaining Ring
The CVH100-COL SMA905-to-SM1 Fiber Adapter with Lens Mount allows the user to mount any unmounted Ø1/2" plano-convex lens and insert it into the beam path for collimation. This adapter can be used in place of the SMA905 fiber adapter included with the CVH100(/M). Use this option to optimize the fiber coupling for specialized setups (e.g., coupling into a large core diameter multimode fiber or if an AR-coated collimating lens is required).
The CVH100-COL ships with 6.8 mm and 9.6 mm spacer rings and a SM05RR retaining ring to secure the lens. Please note that lenses must be purchased separately; please see the table below for a list of recommended lenses. To safely secure the retaining ring, we recommend using either the SPW603 or SPW603L spanner wrench. Please note that plano-convex lenses should be mounted with the plano side facing the fiber (see the drawing to the right).

Fits Cuvettes up to 50 mm (1.96") Tall
- Light-Tight Cover for the CVH100(/M)
- Accommodates Cuvettes up to 50 mm (1.96") Tall, Including the Stopper
- Made of Polystyrene
The CVH100-CV Cuvette Holder Cover is a light-tight cover for the CVH100(/M) cuvette holder. The purpose of this cover is to protect the cuvette from stray and ambient light that would enter from the top of the cuvette holder. When combined with threaded caps (SM1CP2) on the unused ports, this cover can be used to create a light-tight setup.
The cuvette holder cover is able to accommodate cuvettes up to 50 mm (1.96") tall, including the cap or plug, as well as the filter holder included with the CVH100(/M). When a 50 mm tall cuvette is used, there will be 1 mm of clearance between the cuvette stopper and the cover, as seen in the image to the right.
This cover does not effect the cage-compatibility of the cuvette holder, as it does not overhang the upper cage rod holes.
