Optical Mirror
Sunday Optics is a professional optical mirror manufacturer providing custom optical mirrors for laser systems, imaging equipment, spectroscopy, machine vision, medical instruments and OEM optical assemblies. As part of our broader precision optical components range, these mirrors can be customized according to the required wavelength, angle of incidence, polarization, substrate, dimensions, surface quality and reflective coating.
Our precision optical mirrors are available in dielectric, metal-coated, spherical and center-hole configurations. Sunday Optics combines optical processing, polishing, coating, inspection and assembly capabilities to support sample development and repeat production.
Sunday Optics supplies multiple types of precision optical mirrors for laser, imaging, spectroscopy and OEM optical systems. Compare the coating, optical function and required customization parameters below to select the appropriate custom optical mirror.
| Mirror Type | Structure and Optical Performance |
|---|---|
| Dielectric Mirrors | Multilayer dielectric coatings provide high reflectivity over a specified wavelength or wavelength range. Laser-line and broadband coating designs are available. |
| Metal-Coated Mirrors | First-surface optical mirrors with aluminum, silver or gold coatings provide broadband reflection across selected UV, visible, NIR or IR ranges. Protective overcoats can improve durability. |
| Mirrors with Holes | Custom optical mirrors with a center hole provide a clear path for coaxial illumination, beam delivery or mechanical integration. Hole dimensions and edge treatment can be manufactured according to drawings. |
| Spherical Mirrors | Concave or convex reflective surfaces are used to converge, diverge or redirect light. Geometry and coating can be customized for the required optical performance. |
The following values represent current standard or typical manufacturing capabilities. Final specifications should be confirmed according to the mirror material, geometry, clear aperture and coating design.
