G313217329 22.4 mm Dia. N-BK7 Double-Concave Lens; EFL=-150mm 1064nm
This is a G313217329 double-concave lens, featuring a 22.4 mm diameter and a center thickness of 1.5 mm. The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility. The lens has a negative focal length (EFL) of -150mm, making it suitable for use in various applications that require image inversion or reduction.
The lens's concave-concave base shape is symmetrical, with radii of curvature R1 and R2 at -156.22 mm and 156.22 mm, respectively. This shape contributes to the lens's negative focal length and its ability to converge light. The lens's inner and outer radii are both 0, indicating that the lens has a uniform curvature throughout.
The lens is designed for use with a wavelength of 588 nm and comes with a Qio HP Nbar ARHS-YAG coating on both the front and back surfaces. This coating reduces reflection and enhances transmission, making the lens more efficient in transmitting light.
