Stabilized Benchtop Globar Light Source Chapter 3: Product Overview Chapter 3 Product Overview 3.1. Planck's Law and Blackbody 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. The radiation of a black body in thermal equilibrium is described by Planck’s Law: Where is the radiated power per unit area of emitting surface per unit wavelength at temperature... -
Page 6: Optical Configuration
Optical Configuration The SLS203L is a silicon carbide Globar light source. The Globar is placed inside the housing, it is placed at one focus of an ellipsoid reflector. The output from the ellipsoid reflector is then collimated again with a CaF collimating lens. -
Page 7: Beam Profile And Divergence
Beam Profile and Divergence Figure 5 gives an illustration of what the beam profile of SLS203L looks like at near and far field respectively. The near field is defined as right at the output port with the front lens tube removed. The far field is defined as 1m away from the output port of the light source. -
Page 8: Output Stabilization
3.5. Output Stabilization Unlike traditional light sources, the SLS203L will not suffer from a gradual decrease nor short term fluctuation in brightness during its lifetime. SLS203L Silicon Carbide Light Source is equipped with an internal feedback loop and therefore can ensure a constant intensity, low noise and long life span. -
Page 9: Chapter 4 Operation
Setting Up on a Working Surface The SLS203L light source has four non-adjustable plastic feet at the bottom. It can be placed directly onto a flat working surfaces, as shown in Figure 9 (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, thus can be mounted on a breadboard or optical as shown in Figure 9 (b). -
