Request InfoBentham Instruments Ltd.Bentham Instruments Ltd. has developed a cooled housing for 28-mm side-window photomultiplier tubes (PMT). Designed for integration into light-measurement systems that require minimal dark current or temperature-dependent gain variations, the DH-00-Te has a minimum internal temperature of -25 °C with stability better than ±0.1 °C. Dark current is reduced by a factor of 100 for a multialkali PMT. For ease of mounting to other units, the housing has a separate plate that can be drilled and attached. Rigid, lighttight coupling is provided with minimal separation between the source...See full productRelated content from Photonics MediaWEBINARSPhotonics.com 1/18/2018Fiberguide RARe Motheye Fiber: Random Anti-Reflective (RARe) Nanostructures on Optical Fibers as Replacement for AR CoatingsAnti-reflective (AR) coatings are now entering their second century and have remained virtually unchanged throughout their life.
