Adhesive Films for Laser Eye Protection.

摘要

Three plastic films were produced each of which offer protection against several different lasers. The films all have optical densities over 4.5 at the wavelengths 0.3-0.4, 0.84 and 1.06 micrometers, and over 3 at 6.9-11 micrometers. All three films have luminous transmittances of 48%-52%. The 10-mil thick films were prepared with and without a pressure sensitive adhesive backing. Those films with adhesive backing will adhere to both glass and plastic substrates. However, the optical properties of the adhesive backed films are inferior to those of the films without adhesive. Over 50 organic compounds were synthesized and/or evaluated as possible absorbers for the near infrared spectral region. Several of these compound types show promise for application to laser eye protection. Syntheses and properties are discussed.
