L-PCC114 50 mm Dia. Plano-Concave Lens; EFL=-500mm Uncoated

The L-PCC114 is a 50 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 uniformity in light transmission.

The lens geometry is characterized by its diameter, thickness center, effective focal length (EFL), and radii of curvature. The diameter measures 50 mm, and the thickness at the center is 2.5 mm. The EFL is -500 mm, indicating that it is a diverging lens, causing light rays to spread out after passing through it. The radii of curvature are R1=-258.4 mm and R2=0 mm, which are the radii of the curved surfaces of the lens. The inner radius is 0 mm, and the outer radius is also 0 mm, indicating that the lens has a flat outer surface.

The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. The wavelength for which the lens is designed is 587.6 nm. The lens shape is spherical, which is the most common type of lens due to its ease of manufacturing and good optical performance.

The lens does not come with any coating, as indicated in the item data. Coatings are often applied to lenses to improve their optical performance by reducing reflections, increasing transmission, or providing other benefits. However, this lens is uncoated, which may be suitable for certain applications where such coatings are not necessary or desirable.
