Imaging Components

Cosmo Optics has the capability to fabricate a variety of precision optical components including spherical, cylindrical, prisms, plano and more. The materials we work with are varied to be used from UV to the Far IR wavelength bands. Our outer dimensions range from 1.5mm to 1524mm.

Spherical Lenses

A lens is an optical device which transmits and refracts light, converging or diverging a beam of light. A simple lens consists of a single optical element. A doublet or triplet lens is an array of simple lenses (elements) with a common axis; the use of multiple elements allows more optical aberrations to be corrected than is possible with a single element.

Cosmo Optics has a tool and test plate list of over 2,000 radii Click here for Test Plates and Tooling. Our Master Opticians are skilled to make precision lenses from most optical grade materials such as UV Fused Silica and CaF2.

Doublets and triplets are a specialty of ours. Our team of opticians are also highly skilled at centering and cementing multiple spherical lenses together. Doublets and even triplets are perfectly aligned to your specifications. We have the capability to hold tight tolerances for demanding applications for telescopes as well as critical R&D projects.

Plano-Flats

Plano optical components are extremely flat and parallel. These components can be used as windows, wedges or mirrors for a wide variety of applications. Our expert craftsmanship yields incredibly precise plano components. Through our quality measurement system, we can measure and certify flat components up to 12” in diameter at 1/10 wave.

Cylindrical Lenses

A cylindrical lens is a lens which focuses light which passes through on to a line instead of on to a point, as a spherical lens would. The curved face or faces of a cylindrical lens are sections of a cylinder, and focus the image passing through it onto a line parallel to the intersection of the surface of the lens and a plane tangent to it. The lens compresses the image in the direction perpendicular to this line, and leaves it unaltered in the direction parallel to it (in the tangent plane).

Cosmo Optics manufactures plano-convex or plano-concave at various dimensions and sizes. We have made cylindrical lenses greater than 30” in the past.

Prisms

A prism is a transparent optical element with flat, polished surfaces that refract light. At least two of the flat surfaces must have an angle between them. The exact angles between the surfaces depend on the application. Some types of optical prism are not in fact in the shape of geometric prisms. Prisms can be made from any material that is transparent to the wavelengths for which they are designed.

Prisms of all geometric shapes are within our capabilities. We manufacture right angle, dover, penta, penta-roof and more. We can chamfer edges or provide polished ends. Typically, we manufacture large prisms over 4” in length. Feel free to contact us about your prism specifications.
