LC4918 12.7 mm Dia. UVFS Plano-Concave Lens; EFL=-200mm Uncoated
The LC4918 is a plano-concave lens with a diameter of 12.7 mm, sourced from Thorlabs. This lens is designed for use with a wavelength of 588 nm and is uncoated. The lens features a significant negative focal length (EFL) of -200 mm, making it suitable for applications that require strong negative refraction.
The lens's geometry is characterized by its base shape, which is circular, and its thickness at the center, which is 4 mm. The inner and outer radii are both zero, indicating a uniform curvature across the lens. The lens material is UVFS, identified as "UVFS mal- 1965" in the item data.
Please note that the lens does not have any coating, which may affect its performance in certain applications. However, its uncoated status could also make it more versatile, as it can be used in a wider range of environments without the risk of coating damage.
