Did you know that optical mirrors are used in many scientific, industrial, and medical applications, from telescopes and microscopes to laser systems and metrology? Mirrors can be used to reflect, focus, or shape light in many different ways, and they come in a wide range of sizes, shapes, and coatings to suit different applications. There are many types of mirrors available, including concave mirrors, convex mirrors, plane mirrors, and specialty mirrors like laser mirrors and dichroic mirrors. At FindLight.net, we connect you directly with trusted suppliers and manufacturers who offer a wide range of high-quality mirrors, including custom and off-the-shelf options to meet your specific requirements. Our comprehensive search and filtering options make it easy to find the perfect mirror for your project, whether you need a custom mirror for a specific application or a standard mirror for a common application.

Spherical Reflection Mirrors, Off-Axis Parabolic Mirrors, Plano Mirrors With High Reflection Coating

Optical Mirrors are designed to reflect light for a variety of applications, including beam steering, interferometry, imaging, or illumination. Optical Mirrors are used in a wide range of industries, such as life sciences, astronomy, metrology, semiconductor, or solar.

Hyperion Optics offers a range of laser, flat, metal substrate, focusing, or specialty Optical Mirrors in a multitude of reflective coating options, including Protected Aluminum, Enhanced Aluminum, Protected Silver, Protected Gold, or Dielectric. Choosing the proper reflective coating option ensures high reflectivity of the needed wavelength or wavelength range. Optical Mirrors designed for laser applications are optimized for the given laser wavelength. Additionally, Optical Mirrors designed for lasers feature damage thresholds that are suitable for the designated laser. Metal substrate Optical Mirrors are ideal for applications requiring a constant coefficient of thermal expansion between the Optical Mirror and the mount. Optical Mirrors with a concave surface are ideal for light focusing applications.

Optical mirrors have a smooth, highly-polished, plane or curved surface for reflecting light. Usually, the reflecting surface is a thin coating of silver, or aluminum on glass. Product specifications for optical mirrors include diameter, radius of curvature, thickness focal length, and surface quality. The diameter or height of an optical mirror is measured straight on. If the optical mirror&#;s curvature was extrapolated into a sphere, then the radius of that sphere is the radius of curvature for the mirror. There are two thickness measurements for optical mirrors: center thickness and edge thickness. Units of measure include inches, feet, and yards; nanometers, centimeters, and millimeters, and miles and kilometers. With optical mirrors, focal length is the distance from the mirror at which light converges. Surface quality describes digs and scratches. A dig is a defect on a polished optical surface that is nearly equal in terms of length and width. A scratch is a defect whose length is many times its width.

Optical mirrors are made from many different materials, each of which influences the mirror&#;s reflectivity characteristics. Choices for materials include borosilicate glass, copper, fused silica, nickel, and optic crown glass. Borosilicate glass is also known as BK7 and boro-crown glass. Copper is used in high-power applications because of its high thermal conductivity. Fused silica has a very low coefficient of thermal expansion and is suitable for use with moderately-powered lasers or changing environmental conditions. Ultraviolet (UV) grade optical mirrors are also commonly available. Nickel is used in applications which require resistance to both thermal and physical damage. Proprietary materials for optical mirrors include Pyrex (Corning Inc.) and Zerodur (Schott Glaswerke).

Optical mirrors are sometimes coated to enhance their reflectivity. Choices include bare, enhanced, and protected aluminum; silver, bare gold and protected gold; and coatings made from rhodium and dielectric materials. Enhanced aluminum coatings are used to improve reflectance in the visible and ultraviolet regions. Protected aluminum coatings provide abrasion resistance while protecting the surface of the aluminum, an excellent reflector in the upper UV, visible and near-infrared (IR) regions. Optical mirrors with bare gold and protected gold coatings are used in the near-IR to far-IR regions. Silver coatings provide better reflectance than aluminum; however, silver&#;s tendency to oxidize and tarnish requires thorough sealing from the atmosphere. Rhodium coatings have a reflectivity of approximately 80% of the visible spectrum.
