Request InfoBentham Instruments Ltd.Bentham Instruments Ltd. has introduced a large-sample measurement station that employs long-focal- length optics. The company says the device's measurement compartment is as large as some complete spectrophotometers; it can accommodate a 36 3 22 3 30-cm sample. Remov-able light-tight covers and a fixed optical rail allow for quick and easy loading of integrating spheres, goniometers and custom-built sample mounts. The standard wavelength range is 300 to 1100 nm.See full productRelated content from Photonics MediaPRODUCTSPhotonics 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.
