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 Spectra October 2022 IssueLaser Power MeterThe LabMax Touch Pro laser power meter from Coherent Inc. makes data acquisition and analysis for nW continuous wave lasers up to multi-kW, pulsed industrial lasers easy to access through an...BioPhotonics Mar/Apr 2023 IssuePhotodiode PhotodetectorsExtended 2.6-µm Cutoff InGaAs Photodiode Photodetectors from Marktech Optoelectronics Inc. provide high sensitivity, high speed, and low noise for nondispersive spectrometers, pyrometers, and...Photonics Spectra September 2022 IssueLight-Dependent Resistor PhotocellsCadmium Sulfide (CdS) Light-Dependent Resistors (LDRs) from Advanced Photonix Inc. are designed for visible light measurement from 400 to 700 nm.
