SANTA CLARA, CA — ROHM Semicon ductor has introduced its RLD90QZW8 high-power laser diode, ideal for industrial equip- ment and consumer applications requiring distance measurement and spatial recognition. In recent years, LiDAR has
been increasingly adopted in a wide range of applications that require automation, including AGVs, robot vacuums, and autonomous vehicles, where it is necessary to accurately measure distance and recognize space. In this context, there is a need to improve the performance and output of laser diodes when used as light sources to increase detec- tion distance and accuracy. To meet this demand, ROHM
Linear Voice Coil Servo Motor from
Moticont VAN NUYS, CA — Moticont has released the GVCM-022-013-01 linear voice coil servo motor. This compact 0.875 in. (22.2 mm) diameter high speed, high force- to-size linear motor features high accuracy and high repeatability when operated in a closed loop as a DC servo motor. The brushless servo motor runs clean, quiet, and has long life, and offers high acceleration/deceleration for high throughput. This linear voice coil motor,
also known as a moving coil motor or actuator is ideal for: haptic feedback, medical devices, wafer handling, optical focusing, dynam- ic vibration absorption, work hold- ing and clamping, assembly, test- ing, positioning, scanners, laser beam steering, laser speckle cor- rection and filtering. The 0.094 in. (2.4 mm) diam-
eter shaft has a 2-56 UNC-2A thread and exerts 14.5 oz. (4.0 N) of continuous force and 45.7 oz (12.7 N) peak force with a 0.25 in. (6.4 mm) stroke. The housing length is 0.5 in. (12.7 mm) long, the shaft extension is 0.54 in. (13.5 mm) for a total length (including shaft) of 1.22 in. (31 mm). For easy integration into new and existing applications the housing and coil ends have two 4-40 UNC-2B threaded holes on a 0.375 (9.5 mm) bolt circle. Metric series threads are
available in production quanti- ties. A complete line of quadra- ture linear encoders and plug- and-play servo systems including controller, joystick and keypad
are also available. Contact: Moticont, 6901

established original patented technology to achieve a narrower emission width that contributes to longer range and higher accu- racy in LiDAR applications. In 2019, ROHM released the RLD90QZW5 25W laser diode, followed by the RLD90 QZW3 75W laser diode in 2021. In response to the growing market demand for even higher output, ROHM has developed the new RLD90QZW8 120W laser diode. The RLD90QZW8 is a 120W
infrared high output laser diode developed for LiDAR used in dis- tance measurement and spatial
recognition in 3D ToF (time of flight) systems. Original device development technology allows ROHM to reduce the temperature dependence of the laser wave-

length by 66% over general prod- ucts. This makes it possible to narrow the bandpass filter while extending the detection range of LiDAR. At the same time, a uni- form light intensity of 97% is achieved over the industry's smallest class of emission width of 270 µm, representing a range of 264 µm that contributes to higher resolution.
