LPK-25.0-51.9-C 25 mm Dia. N-BK7 Image Grade Plano-Concave Lens; EFL=-100mm Uncoated

The LPK-25.0-51.9-C is a high-quality Plano-Concave Spherical Lens, offered by CVI Laser Optics. This lens, with a diameter of 25 mm, is designed for use in imaging systems and is crafted from N-BK7 Schott glass, a material renowned for its excellent optical properties.

The lens features a concave shape with a radius of curvature of -51.9 mm, resulting in a negative focal length of -100 mm. This makes it suitable for use in various applications where a diverging lens is required. The lens has a center thickness of 2 mm, providing a balance between optical performance and mechanical robustness.

The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. This might make it more susceptible to environmental factors such as dust and moisture, but it also means that it does not introduce any additional chromatic aberrations or other coating-related issues.

The lens is intended for use at a wavelength of 546.1 nm, which is in the green part of the visible spectrum. This makes it suitable for use in a wide range of applications, including microscopy, beam shaping, and laser systems.

The lens is in stock and available for immediate purchase. More detailed information about this lens, including its full specifications, can be found in the linked datasheet.
