36-599 50.8 mm Dia. x 190.6mm EFL; 90° Protected Silver 100A; Off-Axis Parabolic Mirror Protected Silver 450-10000nm

The 36-599 is a high-quality Off-Axis Parabolic Mirror, sourced from the renowned optical vendor, Edmund Optics. This mirror, with a diameter of 50.8 mm, is designed for use in a wide range of applications, particularly where off-axis performance is critical.

The mirror's geometry is defined by a 95.3 mm pupil diameter (PFL) and an effective focal length (EFL) of 190.6 mm, which results in an off-axis angle of 90°. The off-axis design allows for a wider field of view and reduced spherical aberration compared to traditional parabolic mirrors.

The mirror is made from N-BK7 Schott glass, a popular choice for its high homogeneity, low auto-fluorescence, and excellent transmission in the visible and near-infrared regions. The mirror's surface is coated with a protected silver coating, identified as 'edm dprotsil3001000', which provides high reflectivity across the 450-10000 nm spectral range. This coating is also designed to withstand environmental challenges, ensuring longevity and reliability in various operating conditions.
