37-261 12.7mm Dia. x 76.2mm EFL; Protected Aluminum 50A 90° Off-Axis Mirror

This off-axis parabolic mirror, sourced from Edmund Optics, boasts a diameter of 12.7mm and an effective focal length of 76.2mm. It is designed with a protected aluminum coating (edm dprotal300200000) on the front surface, ensuring durability and resistance to environmental factors. The mirror's off-axis angle is 90°, making it suitable for a wide range of applications.

The mirror's geometry is defined by a parabolic shape with a radius of curvature of 76.2mm and an aperture of 19.05mm. The clear aperture (pfl) is 38.1mm, providing a generous area for light transmission. The mirror is made from N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion, making it ideal for applications that require high-quality imaging.

The mirror is designed to operate at a wavelength of 588nm, making it suitable for use in a variety of applications, including spectroscopy, interferometry, and beam shaping. The mirror's off-axis design allows for efficient light collection and minimal aberration, making it a reliable choice for precision optical systems.
