36-589 25.4 mm Dia. x 101.6mm EFL; 90° Protected Silver 100A; Off-Axis Parabolic Mirror Protected Silver 450-10000nm

The 36-589 is a high-quality Off-Axis Parabolic Mirror, sourced from the renowned optical vendor, Edmund Optics. This mirror, with a diameter of 25.4 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 50.8 mm PFL (Pupil Focal Length), 101.6 mm EFL (Effective Focal Length), and a 90° off-axis angle. The off-axis design allows for superior performance compared to traditional parabolic mirrors, particularly in applications where the optical axis is not aligned with the mechanical axis.

The mirror is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and durability. The front surface of the mirror is coated with Edmund Optics' DPROTSIL3001000 coating, a protected silver coating designed to provide high reflectivity across the 450-10000 nm wavelength range. This broadband coating ensures optimal performance in a wide range of applications, from near-infrared to ultraviolet.

The mirror's shape, Off-Axis Parabolic, is a variant of the traditional parabolic shape, designed to provide superior performance when the optical axis is not aligned with the mechanical axis. This makes it ideal for use in applications such as beam shaping, off-axis collimation, and off-axis imaging.
