G314325322 25.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-1000mm 450-700nm
This is a G314325322 Plano-Concave Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens, which has a base shape of a circle, is designed for use in the 450-700nm wavelength range, making it suitable for a wide range of optical applications.
The lens has a diameter of 25.4mm and a center thickness of 1.5mm. The effective focal length (EFL) of this lens is -1000mm, indicating that it is a diverging lens. The radius of curvature (R1) is -523.3mm, and both the inner and outer radii are 0mm, suggesting a simple, straightforward design.
The lens is made from N-BK7, a popular optical glass known for its excellent optical properties. This material is often used in high-precision optical systems due to its low dispersion and high Abbe number.
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, reducing reflections and improving transmission.
