37-245 25.4mm Dia.x 127mm EFL; Protected Gold 50A 90° Off-Axis Mirror Protected Gold 700-10000nm

This is a Protected Gold 50A 90° Off-Axis Mirror, sourced from the renowned optical vendor, Edmund Optics. The mirror boasts a diameter of 25.4mm and an effective focal length (EFL) of 127mm, making it suitable for a wide range of optical applications.

The mirror is designed with an off-axis angle of 90°, which is a crucial factor in many optical systems. The off-axis angle is the angle between the optical axis of the system and the direction of the light ray after it has been reflected by the mirror. This particular mirror's 90° off-axis angle provides versatility and flexibility in designing and implementing optical systems.

The mirror is made from N-BK7 Schott, a high-quality optical glass known for its excellent optical properties. The coating on the front surface of the mirror is Edmund Optics' proprietary protected gold 700-10000nm coating, which enhances the mirror's reflectivity in the specified wavelength range. This coating ensures high-quality performance and durability, making the mirror a reliable choice for various applications.
