This HO-PVL25-3.2C 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 at a wavelength of 587.6nm.
The lens's geometry is characterized by its 25mm diameter, 2.5mm thickness at the center, and an effective focal length (EFL) of -80mm. The concave surface of the lens has a radius of curvature (R1) of -41.729mm, while the plano surface has an infinite radius. The lens does not have any inner or outer radius.
The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and wide transparency range. The lens is coated with a single layer of MgF2 on both the front and back surfaces, which provides superior anti-reflection properties. The coating is designed to operate at 0 degrees angle of incidence (AOI).
The lens is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website at https://www.holmarc.com/plano_concave_lenses.php.
