HO-PVL25-20 25mm Dia. N-BK7 Plano-Concave Lens; EFL=-500mm Uncoated
This is a Plano-Concave Spherical Lens, sourced from Holmarc Opto-Mechatronics, a renowned vendor in the optical industry. The lens has a base shape of a circle and a diameter of 25mm, making it suitable for a wide range of optical applications. The lens's thickness at the center is 2.5mm, and it has an Effective Focal Length (EFL) of -500mm, indicating that it is a diverging lens.
The lens is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties, including high transparency and low auto-fluorescence. This material is widely used in various optical systems due to its superior performance.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating that it is a simple plano-concave lens without any additional curvature on the edges. The wavelength for this lens is 587.6nm, which is in the visible light spectrum.
Notably, this lens does not have any coating, which means it is uncoated. While uncoated lenses can be used in some applications, they may be more susceptible to surface reflections and could benefit from anti-reflective coatings to improve their performance.
