This reflective coating offers high reflectivity (Ravg \u0026gt; 96%) within the wavelength range of 800 nm to 20 μm, making it suitable for beam collimation, focusing, and imaging without introducing chromatic aberration. Metal coatings are prone to oxidation, discoloration, or peeling in high-humidity environments. The SiO₂ protective layer isolates the metal coating from direct contact with air, preventing oxidation and preserving optical performance. Currently, LBTEK offers gold-coated concave mirrors in a 1-inch diameter with a center thickness of 6.0 mm, available in seven focal lengths ranging from -25 mm to -500 mm. In addition to standard products, LBTEK also provides customization services for size, focal length, and operating wavelength.

These mirrors are available in a one-inch size with seven focal lengths ranging from -25 mm to -500 mm and can be used with mirror mounts. Although the metal-coated concave mirrors are protected with a coating, it is recommended to use and store them in low-humidity, room-temperature environments. When handling the mirrors, wear protective products such as latex gloves or finger cots to prevent contamination of the optical surface by oils and residues from fingers.\u003c\/p\u003e","brand":"WaveQuanta","offers":[{"title":"Default Title","offer_id":47515585151130,"sku":"CM10-F250-AU","price":114.51,"currency_code":"SGD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6156\/3546\/files\/1-1_E9_87_91_E5_B1_9E_E8_86_9C_E5_87_B9_E9_9D_A2_E5_8F_8D_E5_B0_84_E9_95_9C_EF_BC_8C_E6_97_A0_E5_AD_94-FlGpbHDqbha5cNYy6R9vpTQbFdLA_56ed3606-63bb-493b-a2c7-bcf8e30e5040.jpg?v=1772636578","url":"https:\/\/waveqvanta.com\/products\/metal-coated-concave-mirror-gold-coating-800-nm-20-0-%ce%bcm-cm10-f250-au","provider":"WaveQuanta","version":"1.0","type":"link"}
