Page 6: Chapter 3 Product Overview
Compact Stabilized Light Sources Chapter 3: Product Overview Chapter 3 Product Overview 3.1. Planck's Law and Black Body Radiation A black body is an object that absorbs all incident electromagnetic radiation (e.g. light), no light passes through or is reflected. However, despite the name, a black body will also emit electromagnetic radiation. -

NIR to MIR range. Figure 2 shows the structure of the tungsten bulb used in SLS201L and SLS202L stabilized light sources. For SLS201L, the filament is sealed in a Quartz Envelope. -
Page 8: Spectrum
3.3. Spectrum The SLS201L tungsten halogen light source generates visible to IR output as far as 2600 nm, with a color temperature of 2796 K. The SLS202L generates output from 450 to 5500 nm with a color temperature of 1900 K. Figure 3 shows the typical output spectra of SLSL201L and SLS202L compared to a theoretical black body spectrum at the corresponding temperature. -
Page 9: Optional Collimator
Optional Collimator Thorlabs also provides optional collimator (not included in the package) for SLS201L and SLS202L. As shown in Figure 5, the collimator works as an alternative to the fiber coupler. It utilize the same focusing lens as in the fiber... -
Page 10: Output Stabilization
SLS201L/SLS202L light source is equipped with an internal feedback loop and therefore can ensure a constant intensity, low noise and long life span. The principle of operation is depicted in the block diagram below. The optical intensity is measured by an internal photodiode, which feeds its monitor signal to the controller unit. -

Figure 7 (a). It also has two 1/4"-20 (M6) threaded mounting hole on the bottom, which are compatible with Thorlabs standard optical posts and post holders, enabling it to be mounted on a breadboard or optical as shown in Figure 7 (b). -
Page 12: Switching On The Light Source
Switching on the Light Source After setting up the light source on a working surface, follow the steps below: Figure 8 Switching on SLS201L/SLS202L Connect the power supply to the 4-pin "Power In" plug on the back panel of the light source;... -
Page 13: Filter Holder
The fiber adapter is pre-adjusted to its optimum position before shipping out and does not require users to re-align in most circumstances. The SLS201L/SLS202L features a quick release mechanism allowing users to easily install and remove the fiber coupler, switching between a free space light source and a fiber coupled one. -
Page 14: Adjusting Fiber Coupler Position
After remove the fiber coupler, users can see the collimating lens in the light source and get access to a roughly collimated beam. The SLS201L light source is shipped with a 1 m long, SMA to SMA fiber patch cable with below specs:... -
Page 15: Application Ideas
There are four 4-40 threaded holes on the front panel of the light source house to allow the integration of Thorlabs’ 30 mm Cage System. The SM1 internal thread in the front lens tube also provides compatibility with Thorlabs’ SM1 Lens Tubes and optical mounts. -
Page 16: Bulb Module Replacement
The electronics inside a light source are ESD sensitive. When performing a bulb module replacement, always wear ESD protection to avoid damaging the light source. Thorlabs offers pre-aligned bulb replacement modules for SLS201L and SLS202L light source. The replacement modules are available on www.thorlabs.com under the SLS251 and SLS252 item numbers, respectively. - Page 17 Compact Stabilized Light Sources Chapter 4: Operation Figure 15 Remove the four screws holding the cover. Then using the 1.5 mm hex key included with the replacement bulb, remove the cap screw that locks the bulb module. Figure 16 Loosen the bulb module locking screw. Unplug the white plug that is connected to the bulb module.
- Page 18 Compact Stabilized Light Sources Chapter 4: Operation Two aluminum dowel pins, located on either side of the bulb module, may slip out of their holes while the module is being removed. Be careful not to misplace them as they are needed for the new module installation. Figure 19 Do not remove the dowel pins on the bulb module.
