HO-PXL50-03 50mm Dia. N-BK7 Plano-Convex Lens; EFL=150mm Uncoated

This is the HO-PXL50-03 50mm Dia. N-BK7 Plano-Convex Lens, a high-quality optical component sourced from Holmarc Opto-Mechatronics. The lens, designed for general use, has a diameter of 50mm and a thickness at the edge of 3mm. It boasts an effective focal length (EFL) of 150mm, making it suitable for a wide range of optical applications.

The lens is made of N-BK7, a popular borosilicate glass known for its excellent optical properties. This material is often used in high-precision optical systems due to its low coefficient of thermal expansion and high homogeneity. The lens's geometry is spherical, with a radius of curvature (R1) of 78.242mm for the convex surface. The inner and outer radii are both zero, indicating a plano-convex design.

The wavelength for this lens is 587.6nm, which falls within the visible light spectrum. This makes it suitable for applications that involve visible light, such as imaging systems, beam shaping, and laser applications.

Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflections, increasing transmission, or providing other benefits, an uncoated lens can be advantageous in certain situations. For instance, uncoated lenses can be more cost-effective and are often used in applications where the elimination of internal reflections is not critical.
