LUK-25.0-117.4-UV 25 mm Dia. UVFS Image Grade Plano-Concave Lens; EFL=-250mm Uncoated

The LUK-25.0-117.4-UV is a high-quality, spherical plano-concave lens, offered by CVI Laser Optics. This lens, with a diameter of 25 mm, is designed for use in UVFS (Ultra Violet Fused Silica) applications, specifically at a wavelength of 404.7 nm.

The lens's geometry is characterized by its center thickness of 6 mm and an effective focal length (EFL) of -250 mm. The concave surface of the lens has a radius of curvature of -117.4 mm. The lens's inner and outer radii are both 0, indicating a uniform curvature across the lens's surface.

The lens is made from UVFS material, identified by the catalog number 1965. This material is known for its excellent transmittance in the UV region, making it ideal for UV applications. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors.

The lens's weblink status is valid and it is currently in stock, according to the vendor's website. The detailed specifications of the lens can be found in the provided weblink. This lens is a great choice for users looking for a high-quality, UVFS plano-concave lens for their optical systems.
