Vacuum deposited inconel on glass or fused silica with the transmission steps and resolution patterns on the same surface. Substrate sizes from 2.0 X 2.0 inches to 7.0 X 7.0 inches.

Row A resolution patterns have opaque backgrounds, while the line transmission varies progressively.

Row B resolution pattern lines are opaque, while the background transmission varies progressively. Line widths from 10 to 500 Ip/mm by the 10th root of 10. Finest detail is 1 micron.

Inconel is a family of austenite nickel-chromium-based superalloys.

Inconel alloys are oxidation and corrosion resistant materials well suited for service in extreme environments subjected to pressure and heat. When heated, Inconel forms a thick, stable, passivating oxide layer protecting the surface from further attack. Inconel retains strength over a wide temperature range, attractive for high temperature applications where aluminum and steel would succumb to creep as a result of thermally induced crystal vacancies. Inconel’s high temperature strength is developed by solid solution strengthening or precipitation hardening, depending on the alloy.
