HO-PVL25-08C 25mm Dia. N-BK7 Plano-Concave Lens; EFL=-200mm Single Layer MgF2
This HO-PVL25-08C optical lens, sourced from Holmarc Opto-Mechatronics, is a 25mm diameter Plano-Concave Spherical Lens with a single layer MgF2 coating. The lens is designed for use with a wavelength of 587.6nm, making it suitable for a wide range of optical applications.
The lens features a concave shape with an inner radius of 0mm and an outer radius of 0mm. The center thickness of the lens is 2.5mm, and it has an effective focal length (EFL) of -200mm. This negative focal length indicates that the lens will diverge light, making it ideal for use in applications such as beam expanders or as a field lens in imaging systems.
The lens is made from N-BK7 Schott glass, a popular choice for its high homogeneity, low auto-fluorescence, and excellent transmission properties in the visible and near-infrared spectral ranges. The lens is coated with a single layer of MgF2 on both the front and back surfaces, which provides excellent anti-reflection properties, reducing surface reflections to less than 1%.
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website or contact 3DOptix directly.
