Request InfoSummers OpticalSummers Optical has introduced a military-specification lens coating hardness kit. It contains a brass instrument for testing severe abrasion resistance and an aluminum instrument for testing moderate abrasion resistance. The former contains a 2 1/2-lb spring and the latter, a 1 1/4-lb spring. The inserts provided with the instruments are manufactured and certified to the MIL-E-12397 standard, and the calibration of the springs is NIST-traceable. Lens coatings can be tested in accordance with MIL-C-00675, MIL-M-13508 and MIL-F-48616.See full productRelated content from Photonics MediaPRODUCTSPhotonics Showcase March 2024 IssueHigh-Quality Optical CoatingsEvaporated Coatings Inc. is a professional and experienced resource for your Thin-Film Optical Coating requirements.
