PLCC-25.4/103.0C 25.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-200mm Uncoated

This is a Plano-Concave Lens from Laser Components, a renowned vendor in the optical industry. The lens, which is uncoated, has a diameter of 25.4 mm and a center thickness of 2.3 mm. The effective focal length (EFL) of this lens is -200mm, making it a negative or diverging lens.

The lens is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties. The curvature of the lens is defined by a radius (R1) of -103mm, indicating a concave shape. The lens does not have an outer radius, and the inner radius is 0, suggesting it is a simple, single-element lens.

This lens is designed to operate at a wavelength of 633nm, making it suitable for a range of applications in the visible light spectrum. The lens is spherical in shape, a common geometry in optical systems due to its ease of manufacturing and versatility.

The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors. This may make it more susceptible to damage or degradation, but it can also make it more cost-effective and suitable for certain applications.
