14OAP-3-127-45-AL 76.2 mm Dia. Aluminum 45° Off-Axis Parabolic Mirror; EFL=148.79mm Protected Aluminum

This is a 14OAP-3-127-45-AL Off-Axis Parabolic Mirror from Standa, a renowned vendor in the optical industry. The mirror has a diameter of 76.2 mm and a pitch factor of 127, making it suitable for a wide range of optical applications. The effective focal length (EFL) of this mirror is 148.79mm, which is a crucial factor in determining the mirror's performance in a system.

The mirror is made of n-bk7 schott, a high-quality optical glass known for its excellent transmission properties and low auto-fluorescence. The front surface of the mirror is coated with sta prot al, a protected aluminum coating that provides high reflectivity and durability. This coating is particularly useful in applications where the mirror is exposed to harsh environmental conditions.

The mirror's off-axis design allows for superior optical performance in systems where a conventional parabolic mirror would introduce aberrations. The alpha angle of this mirror is 0.7853981633974483, which is equivalent to 45°, providing a wide field of view and reducing the need for complex optical alignments.

According to the vendor's website, this item is currently in stock, ensuring quick delivery times. The website also provides further technical specifications and application examples, making it a valuable resource for anyone considering this mirror for their optical system.
