This is a Plano-Concave lens with a 6 mm diameter, sourced from Qioptiq Photonics. The lens is made of N-BK7 glass, a popular material in the optical industry due to its excellent optical properties and versatility. The lens has a center thickness of 1 mm and an effective focal length (EFL) of -10 mm, making it suitable for applications that require a concave lens.
The lens's inner radius is 0 mm, and the outer radius is also 0 mm, indicating a symmetrical curvature. The curvature of the lens is defined by a radius of curvature (R) of -5.012 mm for the concave surface.
The lens is designed to operate at a wavelength of 588 nm, but it can also be used at other wavelengths, making it a versatile component in various optical systems. The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces, providing anti-reflection properties and ensuring high transmission efficiency.
