Focuslight Announces Eye Safe Wide Angle Diffuser for LiDAR and 3D Sensing Applications
"For high-precision detection of distances between vehicles and their static and dynamic environment, the laser beam must be shaped into a light field with a defined field of view," said Kenneth Ferree, VP of Sales and Marketing at Focuslight Technologies. "Thanks to its zero hot spot beam shaping, the new LIMO Wide Angle Diffuser delivers consistent performance, even in extreme operating temperatures. Its expansive illumination area enables full coverage of the 360° surrounding view with just four LiDAR systems for reliable driving safety."
Unlike diffractive optical elements (DOE), which are limited to small angles, moderate ambient conditions, and have an intensity distribution that drops flat at the edges, the LIMO Wide Angle Diffuser is an eye-safe ROE with no zero-order and no "hot spot." The glass material features small refractive index variation and small thermal expansion with temperature, delivering stable performance over a wide temperature range (-40℃~150℃). High uniformity and high window efficiency within the FOV deliver a homogenous intensity profile in angular space with high-quality edges. The end result is high efficiency that allows intelligent use of every generated photon while preventing scattered radiation.
The LIMO Wide Angle Diffuser is available now. OEM prices available on request.
