G314317322 22.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-150mm 450-700nm
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 22.4 mm. The center thickness of the lens is 1.5 mm. The effective focal length (EFL) of this lens is -150 mm, indicating that it is a diverging lens. The lens is designed to work optimally with light in the wavelength range of 450-700 nm.
The lens is made of N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. The lens is unmounted, providing flexibility for users to mount it according to their specific requirements.
The lens is coated with Qio Bbar Arb2visnbk7 on both the front and back surfaces. This coating is designed to enhance the lens's performance in the visible spectrum.
The lens's geometry is defined by its inner and outer radii. In this case, the inner radius is 0, and the outer radius is also 0, indicating that the lens is a simple Plano-Concave design.
