Thorlabs' SLS203F(/M) Stabilized Globar Light Source provides a constant-intensity blackbody radiation spectrum from 500 to 9000 nm in free-space applications and 500 to 4500 nm using ZBLAN fiber patch cables (sold separately). An internal feedback system is employed to achieve a highly stable power output. The superior performance of Thorlabs' stabilized light sources makes them ideal for experiments that require high accuracy and stability, such as transmittance and reflectance measurements.

The SLS203F(/M) light source features an integrated filter holder and fiber-coupling adapter. The source can also be used without the adapter or with the SLS203C collimation package (sold separately below) for 1.4° beam divergence. Internally-threaded lens tubes can also be attached directly to the front of the light source using the SM1QAM Quick-Release Adapter for custom optical systems. The compact housing (see Specs tab) gives the user flexibility with positioning this light source on a crowded optical table. The light source can be post mounted by using the two 1/4"-20 (M6) taps on the bottom of the device and our Ø1" posts.

The front face features four 4-40 taps (as shown in the left image below) for Ø6 mm cage rods, making this device compatible with Thorlabs' 30 mm cage system. The back face has an on/off toggle switch, power indicator LED, and power connection (see image to the bottom right). A filter holder is included with each light source. This filter holder can accommodate Ø1" and Ø25 mm optics up to 0.31" (8.0 mm) thick, allowing bandpass filters to be placed in the light path for applications requiring constant-intensity illumination at a specific wavelength. Alternatively, a sample can be installed in the filter holder between two glass plates, allowing this light source to be used for material analysis. An included SM1RR retaining ring is used to secure the optic inside the holder. We recommend the SPW602 spanner wrench to secure the retaining ring without damaging the optic. The filter holder can be locked into place using the included hex key and a setscrew located on the side of the device. The light sources are also compatible with the CFH2-F filter holder (sold separately below), enabling the user to quickly change between different filters or samples. Additionally, the CFH2-V Variable Attenuator Insert can be used in place of the filter holder to partially or completely block light from passing through the aperture.

Replacement Globars are available below; please see the Globar Replacement tab above for detailed instructions. If a higher color temperature is desired, our color-balancing filters can be used to attenuate red light from the light sources while passing blue light. This results in a beam with a higher color temperature and lower total power.

The removable filter holder (filters sold separately) allows the user to mount Ø25 mm or Ø1" optics inside the stabilized light source. The filter holder can be locked into place with the filter setscrew located on the side of the housing.

The included fiber coupling package can be quickly removed and replaced with a collimation package. The front face of the light source features four 4-40 tapped holes, making it compatible with our 30 mm cage system.

The on/off switch, power indicator, and power input are located on the back of the light source.

The installation instructions and animation below detail the recommended procedure for replacing the Globar module in the SLS203F(/M) Stabilized Light Source. Be sure to install the correct Globar module in its corresponding light source, as the they are not interchangeable.

We strongly recommend wearing gloves when replacing the Globar to prevent skin oils from being deposited onto the Globar. If you suspect the Globar is dirty, carefully clean it with alcohol before connecting it to a power supply.


Globar Replacement Procedure

Open the Cavity

  1. Using a 2 mm hex key, remove the screw closest to the end of the unit on the left and right sides. Do not remove the screws closest to the fan ventilation holes.
  2. Using the same 2 mm hex key, remove the four screws securing the cavity cover, located on the underside of the unit.

Remove the Old Globar

  1. Unplug the white plug that is connected to the Globar module. This plug is located on the far side of the circuit board if the output aperture of the Globar is facing to the right.
  2. Using the 1.5 mm ball-end hex key included with each replacement Globar, remove the cap screw located about half way down on the aluminum divider that separates the PCB chamber and the Globar chamber.
  3. Remove the old Globar by sliding the wire and attached plug out through the hole in the aluminum divider.
    Note: Two aluminum dowel pins, located on either side of the Globar module, may slip out of their holes while the Globar is being removed. Be careful not to misplace them as they are needed for the new Globar installation.

Install the New Globar

  1. Place the two dowel pins in their corresponding holes in the new Globar module.
  2. Slide the new Globar module in the Globar chamber, point up. Pass the wire and plug through the hole in the divider first and then insert the module. The two dowel pins should slide smoothly into the holes in the divider.
  3. While pressing the Globar against the divider, screw the cap screw back in using the included 1.5 mm ball-end hex key.
  4. Insert the white plug back into the circuit board and secure the cavity cover.

Reflection Spectroscopy Application

This broadband light source can be used along with our reflection spectroscopy probes, CCD spectrometers, and fiber probe holders to take diffuse reflection, specular reflection, and color measurements.

Reflection Spectroscopy Fiber Probe Bundle

Spectrometers
Thorlabs offers several CCD-based spectrometers for use in the visible, NIR, or UV to NIR spectral ranges. The CCS100 and CCS175 operate in the 350 - 700 nm and 500 - 1000 nm spectral ranges with 0.5 nm and 0.6 nm resolution, respectively. The extended-range CCS200 operates in the 200 - 1000 nm spectral range with 2.0 nm resolution, but the UV range may be heavily attenuated when analyzing broadband spectra.

Light Sources
The SLS203F(/M) Globar broadband light source, sold below, delivers a 1500 K blackbody-type spectrum in the 500 - 9000 nm wavelength range and has active electronic stabilization for low spectral and intensity drift. Alternatively, the SLS201L(/M) tungsten-halogen light source provides fiber-coupled output with a 2796 K temperature and 360 - 2600 nm emission range. We also offer fiber-coupled LEDs available with a selection of peak wavelengths or a broadband white-light emission spectraand our line of fiber-coupled laser sources offers a selection of options for intense single-wavelength illumination.

Diffuse Reflection Holder

Diffuse Measurement Taken at 45° Using RPH Holder Block

Reflection Probe Fiber Bundles
Thorlabs offers reflection probes with either high-OH or low-OH multimode fiber for wavelengths from 250 - 1200 nm and 400 - 2400 nm, respectively. Probes are available with a sample end that terminates in either a Ø1/4" probe or an SMA905 connector. We also offer Ø1/4" and SMA-terminated probes with linear fiber bundle spectrometer ends for increased spectrometer coupling efficiency for samples with low reflectance.

If the coaxial illumination provided by a reflection probe bundle is not critical, separate fiber patch cables or bundles with SMA connectors can be used for illumination and signal collection. Our large-core round bundles maximize illumination intensity, while our single-fiber multimode SMA patch cables are useful for precise illumination, or for connection to a fiber-coupled laser. We also offer round-to-linear fiber bundles, which maximize signal strength at the spectrometer.

Reflection Probe Holders
Thorlabs offers the RPS and RPS-SMA fiber probe stands (RPS-SMA shown above and to the right), which allow for precise, stable positioning of the fiber optic probe at an angle of 90° or 45° relative to the sample. The probe holder arms (also sold separately) can also be integrated into other optomechanical setups using Ø1/2" posts. Alternatively, the RPH and RPH-SMA probe holder blocks sit directly on a sample, allowing the fiber tip to be positioned close to the surface and also blocking out room lights from the area under test.

Hello, Is the SLS202C Collimation Package compatible with the SLS203L/M light source? Thank you.
cdolbashian  (posted 2024-09-03 04:01:27.0)
Thank you for contacting Thorlabs. The SLS202C and SLS203C have slightly different lenses and pinhole locations in order to provide the best collimation performance when used with the SLS202L(/M) and SLS203F(/M), respectively. The SLS202C can be used on the SLS203L(/M), but we anticipate that its performance will not be optimal. The SLS203C is more suitable for SLS203L/M.

Stabilized Globar Light Source

Simplified Optical Diagram of the SLS203F
Click to Enlarge

The SLS203F(/M) source contains an LA5370 collimating lens and LB5774 focusing lens to couple blackbody radiation into a fiber.

Thorlabs' SLS203F(/M) Stabilized Globar Light Source provides a constant-intensity, 1.8 W blackbody radiation spectrum from 500 to 9000 nm in free-space applications and 500 to 4500 nm using the included fiber focusing package and ZBLAN fiber patch cables (sold separately). Since the blackbody spectrum spans the visible and mid-infrared spectral ranges, this source is ideal for integration into mid-IR measurement and analysis systems. It uses a silicon carbide Globar that is housed in an ellipsoid reflector to increase the optical output. A LA5370 Plano-Convex Lens inside the main housing coarsely collimates the output light and the included fiber package focuses it down onto a fiber tip. The included filter holder is interchangeable with the CFH2-F filter holder, sold below. The SLS203 collimation package (sold separately below) produces a beam with lower divergence.

Additionally, this light source features an internally SM1-threaded (Ø1.035"-40) lens tube at the output of the device. This tube is removable and includes an SM1RR retaining ring which can be used to secure Ø1" or Ø25 mm optics up to 18 mm thick inside it. A low-noise fan inside this light source engages when the temperature exceeds 65 °C to provide temperature regulation. The SLS203F(/M) includes a universal AC/DC power converter capable of accepting 90 - 264 VAC at 47 - 63 Hz.

The SLS203C collimation package attaches using a quick-release mechanism.
  • SLS203C: Collimation Package for SLS203F(/M) Stabilized IR Light Source
  • Collimation Packages for Previous-Generation SLS Sources

The SLS203C collimation package for the SLS203F(/M) Globar IR stabilized light source consists of two collimating lenses and a pinhole packaged inside an internally SM1-threaded (1.035"-40) quick-release lens tube, which is engraved with the item number for easy identification. The SLS203C collimation package contains two LB5774 Uncoated CaF2 Bi-Convex Lenses.

We also offer the SLSC202C and SLSC2 collimation packages for our previous-generation SLS202L(/M) and SLS202(/M) sources, respectively. These collimators are not compatible with the SLS203F(/M) light source sold above.

To install, unthread the fiber adapter from the output of the light source and thread on the collimation package.

Please note that the output beam cannot be perfectly collimated due to the Globar's incoherent emission. The collimation package may be used directly with its compatible light source, or it may be used in conjunction with a Ø1" mounted diffuser attached to the threaded end of the collimation package. The diffuser serves to smooth out the beam profile while increasing the beam divergence angle.

Click to Enlarge
Pushing the adjuster down on the CFH2-V quickly closes the shutter.
  • Inserts Compatible with Our Compact Stabilized Light Sources
  • SM1-Threaded Filter Holder Insert Mounts Ø1" or Ø25 mm Optics up to 0.31" (8.0 mm) Thick
  • Blank Plate can be Machined for Mounting Custom Optics
  • Variable Attenuator Insert with Adjustable Shutter

The CFH2-F Filter Holder accommodates Ø1" or Ø25 mm optics up to 0.31" (8.0 mm) thick and can be used as a replacement for the filter holders included with the light sources sold above. With multiple filter holders, filters can be quickly swapped in and out of the stabilized light sources. The optic is secured against the back lip of the mount using the included SM1RR retaining ring. 

The CFH2-B Blank Plate, also purchased separately, can be used as a manual shutter or machined to suit your specific requirements. The top plate of the CFH2-F and CFH2-B feature two laser-engraved boxes for labeling and identification of the mounted optic. 

The CFH2-V is a variable attenuator insert that is equipped with a black-oxide-coated variable single-blade shutter to partially or fully block light. The shutter moves vertically from the top across the Ø0.54" aperture and is intended for a maximum 0.50" beam diameter. Shutter position is controlled with a 3/16"-120 adjuster that provides 0.005" shutter translation per revolution; fine adjustments can be performed with the included 5/64" hex key. To quickly close the shutter, press the adjuster down (see photo to the right); letting go of the adjuster will return the shutter to the set position (within 0.0005"). For best performance, light after the attenuator insert should be coupled into a fiber optic patch cable as the output beam profile will not be circular. The lamp output will be clipped on the attenuator if the aperture is smaller than the beam size; therefore, the output power will be smaller even if the shutter is completely open.
