Designed for autonomous vehicles, industrial sensing, laser rangefinding, and infrared lighting applications, the new Focuslight LiDAR Tx L LX01 VCSEL line beam transmitter module is an industry first. It combines a multi-junction, high peak power 905nm VCSEL with unique optical beam shaping technology to produce a very uniform line beam (>80%) with FA divergence of<0.15˚ (horizontal) and SA divergence of 23˚ (vertical FOV, customizable). The slow axis divergence angle and energy distribution within the FOV can be customized on request.

The LiDAR Tx L LX01 line beam transmitter is the newest addition to Focuslight’s LiDAR Tx L line beam product line. The overall dimensions are 50.9 mm x 47.9 mm x 78.9 mm. The optical power is 200W, which can be used for new project optical performance evaluation and concept or prototype development.

Compared with line beam transmitter modules based on EEL edge-emitting laser, the LiDAR Tx L LX01 transmitter has core advantages of high-reliability, smaller wavelength temperature shift coefficient, lower sealing requirements, and overall lower cost at high volumes. With an APD array or the new SPAD / SIPM linear array as the LiDAR detector, the resulting LiDAR system can achieve high beam density, high resolution, and longer detection range. It is a preferred light source for next-generation line beam scanning LiDAR. 

Focuslight’s extensive work in automotive applications is based on its beam shaping expertise, laser bar AuSn bonding, electro-optical integration, and IATF16949 certified volume production capabilities.
