The following original and replica gratings, ruled on aluminized, kanigen-coated copper sub-strates are available for use as end reflectors for tuning molecular lasers. With addition of gold(Au) overcoating, the surface reflectivity of these gratings can be increased by a few percent.

CONCAVE MASTER GRATINGS

To order concave master gratings, specify ruled area, size, radius, blaze region, and groove spacing. For available groove spacings and blazes, see table VIII. Concave master gratings are available on standard 5 M or 10 M radii, but we will quote prices for other radii on request.
