Focuslight Technologies, a global provider of high-power diode lasers and micro-optics, has announced the Focuslight BeamRazor™ LE02 pulsed laser line beam transmitter module designed for beam steering LiDAR systems with steering mirrors or MEMS, as well as receivers such as ADP and SPAD/SiPM.
The transmitter 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.

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 divergence angle and energy distribution within the FOV can be customized on request.

"The BeamRazor LE02 line beam transmitter provides high performance, high maturity and manufacturability, and relatively low cost in mass production quantities," said Kenneth Ferree, VP of Sales and Marketing at Focuslight Technologies. "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 the new transmitter and has received good response from the market."
Part of the Focuslight FocusFlux Series, the BeamRazor LE02 line beam transmitter is designed with special materials and an assembly process that meets automotive-grade reliability, production, and quality requirements. It is able to lase as usual under high temperature (+80C) and low temperature (-40C), as defined and required by automotive standards. This enables users to comply with automotive requirements at a system level. Focuslight is also IATF 16949 certified and can provide mass production services and technical solutions for automotive customers.
