Selection overview
Choose optical components by the task they perform
Choose an optical family from the task it performs, then specify wavelength, material, geometry, interface and acceptance criteria. A component name is a starting point; a complete imaging assembly also requires detector or viewing-system information.
| Optical task | Product route | Useful RFQ inputs |
|---|---|---|
| Transmit light through a protective interface | Optical windows | Wavelength, substrate, clear aperture, thickness, flatness, wedge and coating |
| Reflect or redirect a beam | Optical mirrors / Optical prisms | Beam path, angle of incidence, wavelength, polarization, angular or surface tolerances |
| Focus or collimate in two axes | Spherical lenses / Aspheric lenses | Focal length, aperture, conjugates, wavelength, geometry and aberration requirements |
| Shape a beam in one axis | Cylindrical lenses | Powered axis, focal length, aperture, orientation and alignment datums |
| Control transmission or reflection at a surface | Optical coatings | Substrate, wavelength band, incidence angle, polarization and target spectral curve |
| Form a visible or VIS–NIR image; support direct viewing | Objectives and eyepieces | Detector or display, field of view, image circle or eye relief, focus and interface |
| Form an MWIR or LWIR thermal image | Infrared lens assemblies | Band, detector, pixel pitch, F/#, field of view, focus architecture and environment |
Individual element or complete lens assembly?
An individual lens, window, mirror or prism is specified as a component in your optical system. A complete objective must be reviewed together with its detector, spectral response, field of view and mechanical interface. An eyepiece instead requires viewing or display inputs such as eye relief, exit pupil and diopter adjustment.
For a build-to-print inquiry, send the revision-controlled drawing and identify critical inspection items. For a requirement-led inquiry, describe the application and measurable targets so that design responsibility and the proposed supply scope can be agreed.
