Product Details Supplier Info More products

Durable thin film optical coating manufacturer Deposition Sciences (DSI) offers test and measurement capabilities for an array of specialised optical coatings for military and aerospace applications.

The company’s special products group (SPG) participates at all levels of product development, from engineering and prototyping to full-scale production, based on customer specifications.

DSI’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 microns to 50 microns.

Reflectance and transmittance tests range from near-normal to 45deg and cryogenic measurement can be characterised from ambient to

Polarised measurements (SandP) are also available if needed, and hemispherical transmittance and reflectance tests measure from 0.190 microns to 2.5 microns.

Environmental testing is performed to MIL-C-48497 and MIL-F-48616 standards.

DSI’s SPG 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 characterisation (for example, scratch/dig, scatter, and so on), surface resistivity, and dimensional verification.
