This is a 14OAP-4-101.6-45-GM Off-Axis Parabolic Mirror from Standa, a renowned vendor in the field of optical elements. The mirror has a base shape of a circle with a diameter of 101.6 mm, making it suitable for a wide range of optical applications. The off-axis angle (alpha) is 0.7853981633974483 radians or 45 degrees, providing excellent off-axis performance.
The mirror's effective focal length (EFL) is 119.03 mm, which is the distance from the mirror's principal point to the focus of the mirror. This EFL value is crucial in determining the mirror's performance in a specific optical system.
The mirror is made of n-bk7 schott, a high-quality optical glass known for its excellent optical properties. The front surface of the mirror is coated with sta prot gold, a protected gold coating that provides high reflectivity across a wide range of wavelengths, particularly in the visible spectrum.
