HO-PVL25-1.6 25mm Dia. N-BK7 Plano-Concave Lens; EFL=-40mm Uncoated
This is a Plano-Concave Lens from Holmarc Opto-Mechatronics, a leading manufacturer of optical components. The lens, identified as HO-PVL25-1.6, has a diameter of 25mm and a center thickness of 2.5mm. It is designed with a concave surface, featuring a radius of curvature (R1) of -20.865mm, and a plano surface. The effective focal length (EFL) of this lens is -40mm, making it suitable for applications that require a diverging lens.
The lens is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties. This material, also known as Schott glass, has a refractive index of approximately 1.5168 at the wavelength of 587.6nm, which is the reference wavelength used in the manufacture of this lens.
Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their performance by reducing reflection, increasing transmission, or providing other desirable optical properties. However, this lens is designed to operate without a coating, which may be suitable for certain applications.
