Single and multimode VCSEL

The TRUMPF VCSEL portfolio is characterized by a universal functional range in various sensor system applications. The products are used, for example, as a pulse source for time-of flight applications, as a coherent light source in optical encoders, or as reference lasers in FTIR spectrometers. The innovative product design facilitates a low power input, an extremely fast pulsing mode, an optimized beam profile, active polarization control, a spectral light emission with an extremely narrow band and a low speckle effect. Various packaging options also make product integration easier and enable additional features.

Single-mode VCSEL

Single-mode VCSELs are perfectly suited for use in numerous industrial sensor applications due to their Gaussian-shaped beam profile, their low power input, and their outstanding reliability.
TRUMPF offers different wave lengths (for example, 760 nm, 850 nm and 940 nm).

Multimode VCSEL

Multimode VCSELs are infrared light sources for mobile consumer applications and can be perfectly used in highly integrated sensors due to their compact dimensions. 940 nm is the standard wavelength for the multimode VCSEL, however, other wavelengths are also available.
