G314301400 22.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-40mm
The G314301400 is a Plano-Concave lens with a 22.4 mm diameter, sourced from Qioptiq Photonics. This lens is made of N-BK7, a popular material in the optical industry due to its excellent optical properties. The lens features a center thickness of 1.5 mm and an effective focal length (EFL) of -40 mm, making it suitable for applications requiring negative focal lengths.
The lens's geometry includes a radius of curvature (R1) of -20.833 mm, with both inner and outer radii being zero, indicating a plano surface on one side and a concave surface on the other. This specific lens is designed for a wavelength of 588 nm.
The G314301400 lens is coated with Qio Silver RAGV 45 on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, making it ideal for various applications.
Please note that the lens's shape is spherical, a common characteristic in optical lenses. This shape ensures that the lens surface is a segment of a sphere, which is beneficial for imaging and other optical applications.
