HO-PVL50-02 50mm Dia. N-BK7 Plano-Concave Lens; EFL=-100mm Uncoated
This HO-PVL50-02 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 and wide transparency range.
The lens's effective focal length (EFL) is -100mm, indicating that it is a diverging lens, which spreads out light rays. The radius of curvature (R1) is -52.162mm, and the inner and outer radii are 0mm, suggesting a symmetrical concave shape.
The lens is uncoated, meaning it does not have any anti-reflective or other surface treatments. This may result in higher reflective losses and a reduced transmission compared to coated lenses. However, uncoated lenses are often more cost-effective and suitable for applications where such losses are acceptable or can be mitigated.
Please note that the lens's performance is wavelength-dependent, and the provided data is for a wavelength of 587.6nm. Always consult the vendor or refer to the lens's technical specifications for accurate and comprehensive information.
