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

Optical Mirrors are engineered to efficiently reflect light for a wide array of applications including beam steering, interferometry, imaging, and illumination. Their usage spans across numerous industries like life sciences, astronomy, metrology, semiconductor production, and solar energy.

Hyperion Optics provides a diverse collection of optical mirrors, such as laser mirrors, flat mirrors, metal substrate mirrors, focusing mirrors, along with specialized types. These come with several reflective coating choices, including Protected Aluminum, Enhanced Aluminum, Protected Silver, Protected Gold, and Dielectric coatings. Selecting the right reflective coating is vital to ensure optimal high reflectivity for specific wavelengths or wavelength ranges. Optical Mirrors designated for laser applications are finely tuned for particular laser wavelengths and are designed to withstand corresponding intensity levels. Metal substrate mirrors are favored for conditions requiring consistent coefficients of thermal expansion between the mirror and its mounting apparatus. Furthermore, concave optical mirrors are ideal for lighting focusing applications.

Optical mirrors typically consist of a smooth, highly-polished surface that may be flat or curved to maximize light reflection. The reflective surface is generally a thin layer of silver or aluminum applied to glass. Key specifications for optical mirrors include diameter, radius of curvature, thickness, focal length, and surface quality. The diameter is measured in a straight line across the mirror. If conceptualizing the mirror's curvature as part of a sphere, the radius of curvature is derived from that imagined sphere. There are two measurements for optical mirror thickness: center thickness and edge thickness, using units such as inches, feet, yards, nanometers, centimeters, and millimeters. In optics, the focal length signifies the distance where light converges after reflection. Surface quality encompasses any defects such as digs or scratches, where a dig displays roughly equal dimensions for length and width, while a scratch is elongated compared to its width.

Various materials constitute optical mirrors, each contributing uniquely to reflectivity characteristics. Material choices include borosilicate glass, copper, fused silica, nickel, and optic crown glass. Borosilicate glass, also recognized as BK7 or boro-crown, is common. Copper shines in high-power contexts due to excellent thermal conductivity. For its part, fused silica has an incredibly low thermal expansion coefficient, making it suitable for use with moderately-powered lasers or in environments with fluctuating temperatures. Ultraviolet (UV) grade optical mirrors are frequently available. Nickel offers resilience against both thermal and physical challenges. Proprietary materials like Pyrex (by Corning Inc.) and Zerodur (by Schott Glaswerke) also feature prominently in optical mirror production.

Optical mirrors often undergo coatings to enhance their reflective properties. Common coatings include bare, enhanced, and protected aluminum; silver; bare gold; and protected gold, as well as coatings from rhodium and dielectric materials. Enhanced aluminum coatings improve reflectance in both visible and ultraviolet ranges. Protected aluminum coatings cater to abrasion resistance while safeguarding the aluminum base, known for high reflectivity across upper UV, visible, and near-infrared regions. Bare and protected gold coatings are utilized mainly in near-IR to far-IR applications, while silver coatings outperform aluminum but require substantial protection from the atmosphere to prevent oxidation. Rhodium coatings reflect approximately 80% across the visible spectrum.
