HO-PVL50-04 50mm Dia. N-BK7 Plano-Concave Lens; EFL=-200mm Uncoated

This HO-PVL50-04 optical lens, sourced from Holmarc Opto-Mechatronics, is a 50mm diameter Plano-Concave Spherical Lens with a center thickness of 2.5mm. The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties. The effective focal length (EFL) of this lens is -200mm, indicating that it is a diverging lens, which spreads out light rays.

The lens's geometry is defined by its inner radius of 0mm and outer radius of 0mm, with a concave surface radius of -104.323mm. This specific curvature is designed to provide a particular optical effect when light passes through the lens. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors.

This lens is suitable for applications that require light divergence, such as in imaging systems, beam expanders, or other optical instruments. However, due to its uncoated nature, it may not perform optimally in high-intensity light applications or environments with high humidity or temperature fluctuations.
