14OAP-1-25.4-30-GM 25.4 mm Dia. Aluminum 30° Off-Axis Parabolic Mirror; EFL=27.22mm Protected Gold

This is a 14OAP-1-25.4-30-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 25.4 mm and a parabolic surface. The off-axis angle is 30°, making it suitable for a wide range of applications where conventional parabolic mirrors may not be optimal.

The mirror's effective focal length (EFL) is 27.22mm, which is the distance from the mirror's surface to the point where light rays converge. This EFL value is crucial in determining the mirror's performance in a specific optical system.

The mirror is made from n-bk7 Schott, a popular optical glass known for its excellent optical properties and durability. The front surface of the mirror is coated with protected gold, identified as 'sta prot gold' in the coating parameter. This coating enhances the mirror's reflectivity in the visible light spectrum, particularly at the wavelength of 588 nm.

The mirror's geometry, including its diameter, parabolic focal length, and off-axis angle, make it a versatile component in various optical systems. Its protected gold coating ensures high reflectivity and durability, making it an ideal choice for applications that require a robust and high-performing off-axis parabolic mirror.
