The P35940S2G006 from Vertilite is a Vertical-Cavity Surface-Emitting Laser illumination module that operates at a wavelength of 940 nm. It delivers an optical output power of 2.8 W with a power conversion efficiency of 38% and slope efficiency of 1 W/A. This VCSEL diode has a spectral width (RMS) of 1 nm, a beam divergence of 72° (long axis), and 58° (short axis) at FWHM. It has a threshold current of 0.6 A and differential resistance of 0.3 Ω. This laser diode requires a DC supply of 1.9 V and consumes 3.5 A of current. It is available in a tape and reeling package that measures 3.5 ± 0.1 x 3.2 ± 0.1 x 1.2 ± 0.1 mm and is ideal for the time of flight, and IR illumination applications.
