Würth Elektronik WL-VCSL Vertical Cavity Surface Emitting Laser

Würth Elektronik has launches its own infrared laser, extending its comprehensive portfolio of infrared emitters. Made from high-quality materials, the WL-VCSL Vertical Cavity Surface Emitting Laser has a high efficiency of 35% and almost 2 W of radiant power. Designed to emit short, high-energy pulses, the IR laser is suitable for 3D environmental recognition solutions, for example in industrial automation or LiDAR.

The laser’s robust housing measures 3.5 x 3.5 x 1.8 mm and features a thermally conductive ceramic substrate, gold-plated contacts and a high-quality quartz diffuser, all of which enable a homogeneous radiation pattern. Two variants are available: 60° x 45° and 110° x 85° beam angles.

With a wavelength of 940 nm, the laser is aimed at applications in which precision is essential. The possible areas of use range from 3D recognition, LiDAR and distance measurement (time of flight), to solutions in industrial automation and robotics, through to applications in the field of biometric recognition.

The company plans to make a tested reference design available for pulsating controls free of charge.
