34-520 25.4 mm Dia. x 177.8mm EFL; 90° Protected Aluminum 100A; Off-Axis Parabolic Mirror Protected Aluminum

This off-axis parabolic mirror, sourced from Edmund Optics, boasts a diameter of 25.4 mm and a protected aluminum coating, making it an ideal choice for various optical applications. The mirror's 88.9 mm PFL (peak-to-peak flat-to-flat) distance and 177.8 mm EFL (effective focal length) contribute to its exceptional optical performance.

The mirror's off-axis angle is 90°, and it has an a value of 31.75 mm, which is the distance from the mirror's optical axis to its edge. The radius of curvature is 177.8 mm, further enhancing its optical capabilities. The mirror is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence.

The mirror's coating, edm dprotal300200000, is applied to the front surface, providing superior protection and enhancing its durability. This mirror is designed for use at a wavelength of 588 nm, making it suitable for applications that require precise optical performance at this wavelength.
