OSRAM announced that it has strategically acquired a 25.1% stake in Canadian laser radar company LeddarTech, which will strengthen OSRAM's leading position in the field of autonomous driving. LeddarTech, based in Quebec, Canada, was founded in 2007 with advanced technology that complements OSRAM's semiconductor products. In the previous cooperation, OSRAM has invested tens of millions of euros in LeddarTech.
Lidar (light detection and measurement) is similar to radar technology in that it detects objects and measures distance and speed, except that the laser radar is based on infrared light. LeddarTech specializes in the development of solid state laser radar (light detection and measurement) systems that use infrared light to monitor the surrounding environment. Currently, LeddarTech's patented laser radar technology has been integrated into semiconductor and sensor modules for autonomous vehicles and driver assistance systems.
Stefan Kampmann, Chief Technology Officer of OSRAM Lighting Co., Ltd. said: “Osram is the world's leading supplier of self-driving vehicle induction lamps, and market demand in this area is rising. We believe that investing in LeddarTech is to promote OSRAM as the leading solution in this field. The necessary actions of the supplier."
LeddarTech CEO Charles Boulanger said: “There are many similarities between our two companies, and we welcome Osram to be our strategic investor. Osram's investment is an important part of LeddarTech's ongoing large-scale financing program. Financing is expected to be completed soon, and we will provide more details in the future. LeddarTech is committed to being the benchmark for solid-state laser radar in the automotive sector, and we believe that our alliance with automotive lighting market leaders is an important milestone in achieving this goal. significance."

Powell prism is an optical scribing prism.
It allows the laser beam to be optimally divided into a straight line with uniform optical density, good stability, and good linearity after the laser beam passes. Powell prism scribing is better than the scribing mode of Cylindrical Lens, which can eliminate the central hot spot and faded edge distribution of the Gaussian beam.
When a Gaussian laser beam passes through an ordinary cylindrical lens, it will produce unevenly distributed straight lines, while the top of the Powell prism is a complex two-dimensional aspheric surface. When the laser passes through, a large amount of spherical aberration will be generated, redistributing the optical path and reducing the central area The light at the edge increases the light at the edge to form a uniform straight line, which is suitable for various machine vision applications such as biomedicine, automobile assembly, and food processing.
