G063347322 22.4 mm Dia. UVFS Mounted Double-Concave Lens; EFL=-50mm 450-700nm

This is a G063347322 model double-concave lens, featuring a 22.4 mm diameter and a center thickness of 1.5 mm. The lens is mounted on UVFS (Ultra-Violet Fused Silica) material, which is known for its excellent transparency in the ultraviolet, visible, and near-infrared regions of the spectrum.

The lens has an effective focal length (EFL) of -50mm, making it a negative or diverging lens. This type of lens is often used to spread out or diverge light rays, making it suitable for various applications such as beam expansion or collimation.

The lens is designed to work within the wavelength range of 450-700nm, which covers the visible light spectrum. This makes it ideal for use in applications where light in the visible range needs to be manipulated, such as in imaging systems or optical instruments.

The lens features a symmetric concave-concave geometry, with radii of curvature of -50.481mm for both the front and back surfaces. This geometry contributes to the lens's diverging properties. The lens does not have any inner or outer radii, indicating a simple, two-surface design.

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 by reducing reflection and increasing transmission, thereby improving the overall efficiency and quality of the optical system in which it is used.
