Focuslight Announces Pulsed Laser Line Beam Transmitter Module for Beam Steering LiDAR Applications


Download specifications: 

The new Focuslight BeamRazor™ LE02 pulsed laser line beam transmitter module is designed for beam steering LiDAR systems with steering mirrors or MEMS, as well as receivers such as ADP and SPAD/SiPM. It combines a high peak power 905nm pulsed laser with unique optical beam shaping technology. The result is high peak power >600W, short pulse width <5ns, and small beam divergence <0.15 (FA) x 25 degrees (SA) in a compact 55mm x 38mm x 14mm module. The divergence angle and energy distribution within the FOV can be customized on request.

Designed for a wide range of applications in autonomous vehicle LiDAR, 3D / industrial sensing, and machine vision, the BeamRazor LE02 line beam transmitter uses Focuslight’s unique optical beam shaping technology to produce a very small divergence of <0.15deg @FW1/e2 in the horizontal direction (FA) and a very uniform profile with a flat-top distribution in the vertical direction (SA), uniformity >85%, and divergence of 11deg@FWHM or 25deg@FWHM.

The BeamRazor LE02 line beam transmitter provides high performance, high maturity and manufacturability, and relatively low cost in mass production quantities. Combined with a rotating mirror or MEMS for beam steering, and APD or SPAD/SiPM array for signal receiving, the BeamRazor LE02 is an ideal line laser solution for hybrid LiDAR for ultra-high line density, high resolution, and long detection in automotive-grade mass production.

Tanway Technology, a Focuslight partner, has launched an all-new 64-line LiDAR named Scope, which is equipped with Focuslight’s BeamRazor LE02 line beam transmitter and has received good response from the market.
