The 35-553 is a high-quality Off-Axis Parabolic Mirror, sourced from the renowned optical vendor, Edmund Optics. This mirror, with a diameter of 50.8mm, is designed for use in the infrared spectrum, specifically at a wavelength of 588nm.
The mirror's geometry is intricately designed, with a PFL (Parabolic Focal Length) of 76.2mm and an Effective Focal Length (EFL) of 89.28mm. The off-axis angle of this mirror is 45°, making it suitable for applications that require off-axis reflectivity. The mirror's a-value is 27.39, and it has a radius of curvature of 152.4mm.
The mirror is made from N-BK7 Schott, a high-grade optical glass known for its excellent transmission properties and low auto-fluorescence. This material makes the mirror ideal for use in applications that require high precision and clarity.
The mirror's surface is coated with Edmund Optics' proprietary Protected Gold coating, specifically designed for the 700-10000nm wavelength range. This coating ensures high reflectivity and durability, making the mirror resistant to environmental factors and ensuring a long service life.
