Custom Glasswork - Custom Scientific

A fused silica window with four thru-holes. Our high-precision masking process was used to make an ITO coating in a tightly-toleranced circle.

Our capabilities in manufacturing custom optics, filters, and coatings are diverse and broad-based. Some of the optics that we routinely make include precision windows, dichroic beamsplitters, mirrors, high-performance reflectors, prisms, polarizing cube beamsplitters, anti-reflection coatings, lenses, aspheres, ball and half-ball lenses, rod lenses, and semi-spherical lenses.

Please contact us with your requirements or drawings and we will send you a quote. If you don't know exactly what you need, please call or email us and one of our engineers can discuss this with you; you can tell us what you are trying to do and we would suggest the most cost-effective options that would meet your needs.

Below are some images that illustrate some of our capabilities.

Custom, fused silica tube, about 5-inches long. Both the interior and exterior surfaces are polished.

Custom prism-plate. Each of the six surfaces has a precision polish.

Fused silica optical flat, 18"x2", lambda/15 peak-to-valley.

Custom fused silica window, approximately 5-inches dia., 2-inches thick.

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

Small fused silica window with precision bevels and notch, and bandpass filters (in black rings>These spectrally narrow bandpass filters are 4mm dia. and can function in teperatures beyond 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.

Cylindrical lens with high aspect ratio of length and width

Narrowband filter mosaic in machined frame

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.

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.
