L-BCX201 42 mm Dia. Double-Convex Lens; EFL=100mm Uncoated

The L-BCX201 is a spherical lens with a base shape of circular and a double-convex design, sourced from the reputable vendor Ross Optical. This lens is characterized by its 42 mm diameter, making it suitable for a wide range of optical applications. The lens has a center thickness of 6.3 mm and an edge thickness of 2 mm, providing a robust structure while maintaining a sleek profile.

The effective focal length (EFL) of this lens is 100 mm, a feature that contributes to its versatility in various optical systems. The first radius of curvature (R1) is 102.28 mm, and the second radius of curvature (R2) is -102.28 mm, indicating its double-convex geometry. The lens does not have an inner or outer radius, suggesting a uniform curvature throughout.

The L-BCX201 lens is made of n-BK7 Schott material, a high-quality optical glass known for its excellent transmission properties and low auto-fluorescence. This material is ideal for applications that require high precision and clarity. The lens is designed to work with a wavelength of 587.6 nm, making it suitable for applications in the visible light spectrum.

Notably, this lens is uncoated, meaning it does not have any anti-reflective or other surface coatings. While this may result in a higher reflectance at the air-glass interface, it also means the lens is less susceptible to damage from environmental factors or handling.
