This is a Plano-Concave lens, a type of spherical lens, sourced from Qioptiq Photonics. The lens has a base shape of a circle and a diameter of 25.4 mm. The center thickness of the lens is 1.5 mm. The effective focal length (EFL) of this lens is -50 mm, making it a negative or diverging lens.
The lens is made of N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. The wavelength for this lens is 588 nm.
The lens is coated with qio bbar arb2nirnbk7 on both the front and back surfaces. This coating is designed to enhance the lens's performance in specific wavelength ranges, providing benefits such as reduced reflection and improved transmission.
The lens is unmounted, meaning it does not come with any housing or mounting hardware. This allows for flexibility in integrating the lens into various optical systems.
