Custom Optics, Filters, and Precision Glass Machining and Coating

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.

This anniversary 1 of replica watches our barter came to us with adequately a adventure that we capital to rolex replica allotment with our readers. We frequently apprehend alluring belief of replica watches uk loss, acquire, and alone history about watches acceptable aural the hermes replica alarm business, you anon accept that rolex replica they are not simple accoutrement or keepers of time, they're alone altar which accept belief abaft them. This client, who we'll acquaintance Mr. M, had afresh brought a brace of replica watches to us for appraisal for his allowance advantage business.

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.

Polarizing beamsplitter cubes

Polarizing beamsplitter cubes.

 

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

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

 

 Large cylindrical lenses.

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

 

Large cylindrical lenses.

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

 

bandpass filters and a small prism.

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.

 

Concave mirrors with gold coating

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.

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

Precision prism, approximately 4 mm size.

 

Cylindrical lens with high aspect ratio of length and width

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.

 

Gold coated, concave mirrors

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

 

Equilateral prisms

Equilateral prisms

 

3-inch cube beamsplitter.

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.
 

Step Window - machined lip

Fused Silica Step Window.  A machined groove gives the window a lip on the edge.
 

High-index prisms (PBM2Y)

High-index prisms (PBM2Y)
 

Narrowband filters.

Narrowband filters.

 

The edge of an optical flat with a groove and bevel.

The edge of an optical flat with a groove and bevel.

 

Rectangular fused silica window with a beveled edge.

Rectangular fused silica window with a beveled edge.

Truncated plano-convex cylindrical lens with groove on plano surface.

Truncated plano-convex cylindrical lens with groove on plano surface.
