L-BCX273 100 mm Dia. Double-Convex Lens; EFL=175mm Uncoated

The L-BCX273 is a 100 mm diameter double-convex lens, supplied by Ross Optical. This lens boasts an effective focal length (EFL) of 175mm, making it suitable for a wide range of optical applications. The lens is uncoated, offering users the flexibility to apply their preferred coating based on their specific requirements.

The lens's geometry is characterized by its circular base shape, with a thickness at the edge of 3.9mm and a center thickness of 18.2mm. The radii of curvature for the first and second surfaces are 177.72mm and -177.72mm respectively, indicating a strongly converging lens. The lens does not have an inner or outer radius, suggesting a uniform curvature across the entire surface.

The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It is designed to work optimally with light of wavelength 587.6nm. The lens's spherical shape allows for efficient light gathering and focusing, making it ideal for imaging and other applications where high light transmission and focus are required.

Please note that the lens is uncoated, which means it may be more susceptible to environmental factors such as dust, moisture, and scratches. However, this also provides the user with the opportunity to customize the lens with a coating that best suits their needs, whether it's for anti-reflection, scratch resistance, or other purposes.
