14OAP-3-76.2-45-GM 76.2 mm Dia. Aluminum 45° Off-Axis Parabolic Mirror; EFL=89.28mm Protected Gold

This is a 14OAP-3-76.2-45-GM Off-Axis Parabolic Mirror, a high-quality optical component sourced from Standa. The mirror has a base shape of a circle, with a diameter of 76.2 mm and a parabolic surface that deviates from the optical axis by 45°. This specific model is designed for use at a wavelength of 588 nm.

The mirror's geometry includes a clear aperture (pfl) of 76.2 mm and an effective focal length (EFL) of 89.28 mm. The off-axis angle (alpha) is 0.7853981633974483 radians or approximately 45°. This mirror is made of n-bk7 Schott glass, a popular choice for its high refractive index and low dispersion.

The mirror's surface is coated with protected gold, denoted as "sta prot gold". This coating is known for its high reflectivity in the visible and near-infrared regions of the spectrum, making it suitable for a wide range of applications. The coating is also protected, which enhances its durability and resistance to environmental factors.
