Request InfoPrinceton Optronics Inc.Princeton Optronics Inc. has announced high-power vertical-cavity surface-emitting laser (VCSEL) arrays with top-mounted diffusers for 3D imaging applications. The 860- and 940-nm devices are used for IR illumination for time-of-flight or other distance measurements. The diffusers are able to modify the divergence angle from the native 20° round beam to a maximum of 110 × 90° divergence. Other divergence angles such as 65 × 45° are also available. The 860-nm illuminators are used predominantly in indoor applications, while the 940-nm illuminators are used...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra December 2023 IssueCompact Proximity SensorThe RPR-0720 from ROHM Semiconductor is a compact 2.0 mm × 1.0 mm proximity sensor for applications requiring attachment, detachment, and proximity detection.
