Environmental Testing

CVI Laser Optics is a valued supplier of critical optical components able to withstand the rigors of the most severe environments in defense and industrial applications. All tests, where applicable, are carried out per MIL specifications and on a representative witness, piece coated in the same batch.

Static Humidity Test

A standard test typically performed over 24 hours in 98% relative humidity at 49°C. This can be varied for customer specific requests. For hard carbon coatings and STAR coatings, this test would be performed for 7 and 10 days, respectively.

Cycling Humidity Test

This test is performed only by specific request from a customer. Typically performed at 98% relative humidity between 35°C and 65°C. This test can be performed at other temperatures and relative humidity by request.

Salt Solution Test

A standard test typically performed over 24 hours. By customer request, this can be extended up to 7 days.

Salt Spray (Fog) Test

This test is typically performed over 24 hours at 47°C. By customer request, this can be extended up to 90 days.

Temperature Test

A standard test which cycles between hot and cold temperatures, typically between -62°C and + 71°C for 5 hours each. The temperature and duration can be varied to the customer's specific requirements. We also have the capability to perform thermal shock tests upon request.

Abrasion Test

A standard test varying from moderate abrasion with cheesecloth to severe abrasion with an eraser at a known pressure. Other abrasion tests that can be carried out include sand abrasion and windscreen wiper abrasion.

Adhesion Test

A standard test performed using adhesive tape to a known specification

Solubility & Cleanability Test

This test is performed only by specific request from a customer. Typical chemicals used would be acetone, IPA, or AG101.

Chemical Degradation Test

This test is performed only by specific request from a customer. A coated witness sample would be subjected to chemical attack using customer specified chemicals.

Shock & Vibration Test

This testing is used to simulate the worst care handling and shipping environments of mounted components and complex optical systems to the limits of lifetime exposure. This testing protocol assures products delivered are robust.
