14OAP-1-127-45-AL 25.4 mm Dia. Aluminum 45° Off-Axis Parabolic Mirror; EFL=148.79mm Protected Aluminum

This is a 14OAP-1-127-45-AL 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, making it suitable for a wide range of optical applications.

The mirror's geometry is specifically designed with a focal length (pfl) of 127 mm and an effective focal length (efl) of 148.79 mm. This configuration allows for precise focusing and collection of light, which is crucial in many optical systems. The off-axis design, with an alpha angle of 0.7853981633974483 radians (or 45 degrees), provides a clear aperture without the central obstruction typically found in on-axis systems, enhancing its performance in off-axis applications.

The mirror is made from n-bk7 Schott glass, a material known for its excellent optical properties and high damage threshold. It is coated with protected aluminum (sta prot al) on the front surface, providing high reflectivity across a wide range of wavelengths, specifically at 588 nm. This coating also ensures durability and resistance to environmental factors, making it suitable for use in various conditions.
