35-581 76.2mm Dia. x 272.2mm EFL; 30° Protected Gold 100A; Off-Axis Parabolic Mirror Protected Gold 700-10000nm

The 35-581 is a high-quality Off-Axis Parabolic Mirror, sourced from the renowned optical vendor, Edmund Optics. This mirror, with a diameter of 76.2mm, is designed for use in a wide range of optical systems, particularly those requiring precise off-axis reflectivity and minimal aberration.

The mirror's geometry is carefully crafted, with a PFL (Pupil to Focal Length) distance of 254mm and an Effective Focal Length (EFL) of 272.23mm. This configuration ensures a well-focused beam at the desired location, enhancing the overall performance of your optical system. The off-axis angle of 30° provides the necessary angular deviation, allowing for efficient light collection and reflection without vignetting.

The mirror is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and high damage threshold. This material ensures high transmission across a broad spectrum, making the mirror suitable for various applications.

The mirror's surface is coated with Edmund Optics' Protected Gold 700-10000nm coating, which provides high reflectivity (98%) in the 700-10000nm wavelength range. This coating is designed to withstand harsh environmental conditions, ensuring longevity and reliability in your optical system.
