Request InfoHolo/Or Ltd.Holo/Or Ltd. has announced a diffractive optical element (DOE) Tuner to make small adjustments to the output characteristics of a DOE. Placing the DOE Tuner between the DOE and the focusing lens allows for image size control in most elements. In multispot beam splitters, finer control is allowed over the separation angle. The DOE Tuner can also be placed before the DOE in order to fine-tune the input beam size. In beam splitter elements, this placement can also control the output spot size. For top hat beam shapers, nominal beam size can be achieved.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 8/24/2022Digital Output EncodersNisshinbo Micro Devices Inc.’s NJL5821R and NJL5822R two-phase digital output encoders with optical reflection have been announced by MACNICA ATD Europe GmbH and are suited for detecting...Photonics Spectra January 2023 IssueDigital Fiber Optic GyroscopeThe Boreas D70 digital fiber optic gyroscope from Advanced Navigation is an inertial navigation system for surveying, mapping, and navigation across subsea, marine, land, and air applications. ...Photonics.com 8/29/2023Laser RangefinderThe L1535 LASER RANGEFINDER by Lumispot Tech is based on the company’s 1535 nm Erbium-doped glass laser model with a focus on eye safety reaching Class 1 human eye safety standards.
