DSI: Rugged Optical Coatings and Testing per MIL Specs
Rugged optical coatings.
Santa Rosa, CA — Deposition Sciences, Inc. (DSI), manufacturer of durable thin film optical coatings, offers extensive test and measurement capabilities for a wide array of highly specialized optical coatings for military and aerospace applications. DSI's Special Products Group (SPG) participates at all levels of product development, from engineering, to prototyping, to full-scale production, based on customer specifications.

The company's quality testing capabilities include measurement of in-house produced materials as well as independent verification of external coated samples for vendor/supplier surveillance, process analysis, and qualification testing.

SPG's spectral measurement capabilities include testing spectral ranges from 0.190 to 50µ. Cryogenic measurements can be characterized from ambient to <10° Kelvin. Polarized measurements are also available, if needed, and hemispherical transmittance and reflectance tests measure from 0.190 to 2.5µ.

Environmental testing is performed to MIL-C-48497 and MIL-F-48616 standards. The company can perform tests for humidity, salt, fog, abrasion, temperature cycle, adhesion, solubility and cleanability. Physical test and measurements available include flatness/reflected wavefront error, surface quality characterization (e.g. scratch/dig, scatter, etc.), surface resistivity, and dimensional verification.
