IPS has provided both Superluminescent Diodes (SLDs) and Lasers for numerous systems and applications.  For these applications it is generally important to “de-speckle” the laser if used for illumination.  This can be accomplished by using a diffuser or a vibrating ground glass plate into the beam path to scramble the coherence of the beam. 

IPS Applications - Illumination

SLDs are typically utilized for this application due to their low coherence and superior beam quality properties in comparison to light emitting diodes; making them “high brightness” sources that are easy to focus and collimate. 


Wavelength stability is generally not a property that is needed for this application space. 


Finally, beam-shaped sources, such as the stub laser can be utilized to tailor the area of uniform illumination.
