Aluminum Rectangular Plano Mirrors
LINOS® Aluminum Rectangular Plano Mirrors are versatile optical components designed for high-performance reflection across a wide range of applications, enabling users to achieve precise, efficient optical results. These standard mirrors are available for the visible to infrared or the ultraviolet spectral ranges, delivering high reflection across broad spectral and angle-of-incidence ranges for reliable performance in diverse settings. VIS–IR mirrors feature a protective SiO₂ overcoating, while UV mirrors are protected with an MgF₂ overcoating, ensuring long-lasting durability and resistance to environmental influences, giving users peace of mind. Manufactured from low-expansion substrates, they maintain thermal stability and surface flatness, minimizing distortion and supporting consistent accuracy under varying conditions.
Custom substrates or coatings are available for specialized requirements in larger quantities upon request. These aluminum plano mirrors offer reliability, versatility, and precision, making them suitable for laboratory research, industrial optics, spectroscopy, and laser systems that require consistent, high-performance reflection.
