Custom Optics, Filters, and Precision Glass Machining and Coating

4"x 4"  cylindrical lenses. These Plano- concave and plano-convex lenses are high power with an f/1 focal ratio.

4 mm dia. bandpass filters and a small prism. These narrow bandpass filters each have a different, high-precision passband and deeply attenuate unwanted wavelengths. They can withstand temperatures to 100 degrees C.

3" dia. Concave mirrors with precision holes and gold coating.  These mirrors are used to make an optical cavity for Infrared light.

Aluminum-coated mirror with thru-hole that has counter-bore. This hole makes a 45 degree angle with the surface. The diameter of the hole changes in the middle of the substrate. The aluminum-coated surface is facing down.

Precision prism, approximately 4 mm size.

Cylindrical lens with high aspect ratio of length and width.

Large size, narrow bandpass filter, 12 x 12 inches (300 x 300 mm). Due to the narrow bandwidth of this filter, it was fabricated as a mosaic of four elements 150 x 150 mm each and mounted in a custom- machined aluminum frame.

Three mirrors with gold coating. All the mirrors, including the rectangular one, have a high-precision, concave, spherical curvature.

Equilateral prisms

3-inch cube beamsplitter.

Housing and contents for liquid CuSO₄  filter.  This combination of
glass UV optical filters forms a hermetically sealed cavity that
holds a volume of blue liquid CuSO₄.  This unique assembly provides a UV filter that has high transmission in the ultraviolet and good
blocking of unwanted visible and near infrared light. Photo inset shows magnified image of nylon set-screw that seals hole used to fill cavity. When filter is filled, set-screw would be hidden inside filter housing. A jar of CuSO₄ is in the background.
