35-491 25.4mm Dia. x 54.4mm EFL; 30° Protected Gold 100A; Off-Axis Parabolic Mirror Protected Gold 700-10000nm

This off-axis parabolic mirror, sourced from Edmund Optics, boasts a diameter of 25.4mm and a PFL (Parabolic Focal Length) of 50.8mm. The Effective Focal Length (EFL) is 54.45mm, making it suitable for a variety of optical applications. The off-axis angle is 30°, and the a value is 13.16mm, while the radius of curvature is 101.6mm.

The mirror is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. The coating on the front surface is Edmund Optics' Protected Gold 700-10000nm, which provides high reflectivity across the 700-10000nm wavelength range and excellent environmental stability.

This mirror is designed for use in the near-infrared region of the spectrum, making it ideal for applications such as thermal imaging, spectroscopy, and beam shaping. Its off-axis design allows for a wider field of view than traditional parabolic mirrors, making it a versatile choice for many optical systems.
