L-PCX143 15.5 mm Dia. Plano-Convex Lens; EFL=49.8mm Uncoated

The L-PCX143 is a Plano-Convex lens with a diameter of 15.5 mm, making it suitable for applications requiring compact optical components. This lens is manufactured by Ross Optical, a reputable vendor known for its high-quality optical elements.

The lens features an effective focal length (EFL) of 49.8 mm, which is a critical parameter in lens selection. The EFL determines the distance between the lens and the image sensor or the object being imaged, influencing the overall system's design and performance.

The lens's geometry includes a thickness of 1.8 mm at the edge and 3 mm at the center. This design provides a balance between optical performance and mechanical robustness. The lens's base shape is circular, contributing to its compact form factor.

The L-PCX143 is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. This material is particularly suitable for applications in the visible spectrum, as indicated by the wavelength of 587.6 nm.

Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their performance by reducing reflections, increasing transmission, or providing other desirable optical properties. However, an uncoated lens can be advantageous in certain applications where specific coating properties are not required, or cost considerations are a priority.
