L-PCC104 47 mm Dia. Plano-Concave Lens; EFL=-50mm Uncoated

The L-PCC104 is a 47 mm diameter Plano-Concave lens, part of the extensive catalog offered by Ross Optical. This lens is designed for use in optical systems where a negative focal length is required. The base shape of the lens is circular, ensuring symmetry and ease of integration into various optical arrangements.

The lens's geometry is characterized by its diameter of 47 mm and a center thickness of 2 mm. The effective focal length (EFL) is -50 mm, indicating its concave nature. The radius of curvature (R1) is -25.84 mm, further emphasizing its negative focal length. The lens's inner and outer radii are both zero, suggesting a uniform thickness across the lens.

The lens is made from n-BK7 Schott, a popular optical material known for its high refractive index and low dispersion. This makes it suitable for a wide range of applications, particularly where high image quality and low chromatic aberration are essential. The lens is designed to operate at a wavelength of 587.6 nm.

Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflection, increasing transmission, or providing other benefits, an uncoated lens can be advantageous in certain applications. For instance, it can offer a more cost-effective solution or be more suitable for use in specific wavelength ranges.
