Product Info
850-nm single-mode VCSELs
850-nm single-mode VCSELs are the perfect choice for demanding sensor applications due to their improved optical characteristics. Higher-order longitudinal and transversal modes are suppressed by the innovative chip design; at the same time, the polarization is linearly stable.
Gaussian-shaped beam profile
The absolutely symmetrical and Gaussian-shaped beam profile makes the optical design of your application significantly easier.
Low beam divergence
A reproducible divergence angle in the range of 20° (1/e2) makes beam guidance easier.
Low spectral width
The laser line with a spectral width of a typical figure of 100 MHz makes this laser perfect for spectroscopic applications.
Low power input
A power input in the range of a few milliwatts allows battery operation in mobile applications.
