The VCProbe-NIR-DSD is specially designed to precisely measure the angular emission of small aperture of NIR sources. This system can measure many different sources including LIDAR, Flash LIDAR, Laser Diode and VCSEL.



The system features contactless measurements that generates, within a single measurement, the viewing angle of ±32° that provides an outstanding angular resolution of 0.03°. For NIR viewing angle measurements up to ±70°, see VCProbe-NIR-STG

It is a system optimized for individual VCSEL and has a Working Distance of 40mm.

The VCProbe-NIR-DSD allows high speed and accurate measurements for applications in R&D as well as mass production/QC.

Customized systems to meet your exact requirements are available.
