Request InfoFOCtek Photonics Inc.With Foctek Photonics Inc.’s penta prisms, users can deviate an incident beam to 90° without inverting or reversing. Made of BK7 Grade A optical glass, the components have a ±0.2 mm dimension tolerance. They feature reflectivity of >90% per face at 400 to 700 nm and better than 60-40 scratch-and-dig surface quality. Users may order the prisms uncoated or with antireflection coating on the input and output sides. The components are commonly used for plumbing levels, surveying, aligning, rangefinding and optical tooling.See full productRelated content from Photonics MediaPRODUCTSPromoted Content March 2024 IssuePrecision Polished SubstratesOhara is a world-class manufacturer of high-quality double-side lapped and polished substrates suitable for use at 248 nm.
