This is the HO-PVL50-20 50mm Dia. N-BK7 Plano-Concave Lens, a high-quality optical component sourced from Holmarc Opto-Mechatronics. The lens, which is uncoated, has a base shape of a circle and is designed for use in spherical optical systems.
The lens has a diameter of 50mm and a center thickness of 2.5mm. It is designed with a concave surface, featuring an inner radius of 0mm and an outer radius of 0mm, and a radius of curvature (R1) of -521.616mm. This design gives the lens an effective focal length (EFL) of -1000mm, making it suitable for use in systems requiring strong negative magnification.
The lens is made from N-BK7, a popular optical glass from Schott. This material is known for its excellent optical properties, including a high Abbe number and low dispersion, making it ideal for use in a wide range of optical applications.
The lens is designed to operate at a wavelength of 587.6nm. It does not come with any coating, which means it is in its most basic form, ready to be integrated into an optical system or coated according to specific application requirements.
