Designed to accommodate standard micro and macro cuvettes, the CVH100 Cuvette Holder can be used in fiber or free-space applications. The holder 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).

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. ![]() ![]() Click to Enlarge Lens is Not Included with the CVH100-COL
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. Please note that plano-convex lenses should be mounted with the plano side facing the fiber (see the drawing to the right). ![]() ![]() Click to Enlarge Fits Cuvettes up to 50 mm (1.96") Tall
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. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
