This is a high-quality dielectric mirror from Altechna, designed for broadband applications in the 400-700nm range. The mirror, identified as 1-OS-1-0254-6-[2A45], features a circular geometry with a diameter of 25.4mm and a thickness of 6mm, making it suitable for a wide range of optical systems.
The mirror is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and high damage threshold. The coating on the front surface is an ALT 400-700 AOI 45, specifically designed to provide high reflectivity across the broadband spectrum of 400-700nm. This coating is applied at an angle of incidence of 45 degrees, ensuring optimal performance in most optical systems.
The mirror's shape is that of a thin lens, which can be beneficial in certain applications where thin, lightweight optical elements are required. The mirror is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website at https://www.altechna.com/products/hr-broadband-mirrors/.
