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 10 mm. The center thickness of the lens is 1.5 mm. The effective focal length (EFL) of the lens is -16 mm, indicating that it is a 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, in this case, 725-1050nm.
Please note that the lens is unmounted, meaning it does not come with any housing or mounting mechanism. This allows for flexibility in integrating the lens into your system, but you will need to provide your own mounting solution.
The lens is currently in stock and available for purchase. For more information, please refer to the vendor's website linked below.
