Single and multimode VCSEL

The TRUMPF VCSEL portfolio is characterised by a universal functional range in various sensor system applications. For example, the products are used as a pulse source for time-of flight application, as a coherent light source in optical encoders or as a reference lasers in FTIR spectrometers. The innovative product design facilitates a low power input, an extremely fast pulsing mode, an optimised beam profile, active polarisation 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, 850 nm

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).

Multi-Mode VCSEL Polarisationskontrolle

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.
