The very small wavelength drift with temperature (0.07nm/°C) enables narrower bandpass filters to be used, which decreases ambient light interference, improving Signal to Noise ratio and extending the effective range.
These VCSELS are available in SMD and TO packages with wavelengths of 808nm, 850nm and 940nm. Multichannel VCSEL arrays with 4, 8 or 16 emitters are also available.
