This is a 14OAP-2-127-30-AL Off-Axis Parabolic Mirror from Standa, a renowned vendor in the optical industry. The mirror has a diameter of 50.8 mm and a focal length of 127 mm, resulting in an effective focal length (EFL) of 136.12 mm. The off-axis angle (alpha) is 0.5236 radians or approximately 30°.
The mirror is made of n-bk7 schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. The coating on the front surface is protected aluminum (sta prot al), which provides high reflectivity and durability.
This mirror is designed for use in a wide range of optical systems, including beam shaping, focusing, and collimation applications. Its off-axis design allows for superior optical performance in systems where space constraints or other factors prevent the use of a traditional on-axis parabolic mirror.
The mirror is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website at http://www.standaphotonics.com/off-axis-mirrors/off-axis-parabolic-mirrors.php.
