This is a 25.4mm diameter Off-Axis Parabolic Mirror, sourced from the renowned optical vendor, Edmund Optics. The mirror has a 63.5mm PFL (Position From Lens) and an effective focal length (EFL) of 127mm, making it suitable for a wide range of optical applications.
The mirror features a 90° off-axis angle, which is crucial for applications requiring off-axis reflectance. The off-axis angle is measured from the optical axis, and in this case, it is 90°, meaning the mirror reflects light at a right angle to the incoming beam.
The mirror is made from N-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. This material is widely used in various optical systems due to its superior optical properties.
The mirror is coated with Edmund Optics' Protected Gold 700-10000nm coating on the front surface. This coating provides high reflectance (R > 95%) in the 700-10000nm wavelength range, making it ideal for near-infrared (NIR) and short-wave infrared (SWIR) applications. The 'protected' nature of the coating ensures durability and resistance to environmental factors, enhancing the mirror's longevity and reliability.
