14OAP-2-127-30-GM 50.8 mm Dia. Aluminum 30° Off-Axis Parabolic Mirror; EFL=136.12mm Protected Gold

This is a 14OAP-2-127-30-GM Off-Axis Parabolic Mirror, a high-quality optical component sourced from Standa. The mirror has a diameter of 50.8 mm and a focal length of 136.12 mm, making it suitable for a wide range of optical applications.

The mirror's off-axis design, with an alpha value of 0.5235987755982988 (approximately 30°), allows for superior optical performance in off-axis applications, reducing spherical and coma aberrations compared to traditional spherical mirrors.

The mirror is made from N-BK7 Schott glass, a widely used material in optical systems due to its excellent optical properties and high damage threshold. The front surface of the mirror is coated with Sta Prot Gold, a protected gold coating that provides high reflectivity in the visible spectrum, specifically at 588 nm.

This mirror is available for purchase directly from Standa, and the provided weblink (http://www.standaphotonics.com/off-axis-mirrors/off-axis-parabolic-mirrors.php) provides more information about this product, including its availability and pricing.
