Request InfoOptronic Laboratories LLCGooch & Housego has announced the release of the OL 730E series radiometers/photometers. The newest model has a smaller footprint, while providing similar research-grade precision and accuracy. Its internal preamplifier delivers sensitivity of 1 x 10—14 A. It is controlled via a USB interface. Response time is 0.1 s, and full-scale sensitivity ranges from 2 x 10—10 to 2 x 10—3 A. Also being offered with the radiometers/photometers is a series of thermoelectrically cooled detectors that provide enhanced temperature stability over time while using a smaller control unit.See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 2/6/2024Laser Energy DetectorThe QE195LP-S-MB from Gentec-EO is a pyroelectric laser energy detector specifically made to measure lasers with extra wide beams in applications such as advanced materials research and processing,...Photonics.com 8/24/2022Ethylene Oxide Monitoring SystemThe Ambient Air Monitoring System for Ethylene Oxide (EtO) has been announced by Picarro Inc., providing a continuous, automated solution for community monitoring stations and industrial fencelines....Photonics Spectra March 2023 IssueOptical Inspection SystemThe Photon Optical Inspection System from LMI Technologies Inc. provides fast, high-precision scanning of manufactured materials.
