This is a Protected Gold 50A 90° Off-Axis Mirror, sourced from the renowned optical vendor, Edmund Optics. The mirror, with a diameter of 12.7mm and an effective focal length of 25.4mm, is designed for use in the 700-10000nm wavelength range, making it suitable for a wide range of applications, particularly in infrared spectroscopy and imaging.
The mirror's off-axis angle is 90°, and it features a parabolic shape with a radius of curvature of 25.4mm. This design ensures excellent optical performance, with minimal spherical aberration and distortion. The mirror's protective gold coating on the front surface further enhances its durability and resistance to environmental factors, ensuring long-lasting performance.
The mirror is made from N-BK7 Schott glass, a material known for its excellent optical properties and high damage threshold. This makes the mirror suitable for high-power applications. The mirror's geometry, including its diameter, effective focal length, and off-axis angle, are all precisely controlled to ensure accurate and consistent performance.
