L-BCX257 75 mm Dia. Double-Convex Lens; EFL=200mm Uncoated

The L-BCX257 is a 75 mm diameter double-convex lens with an effective focal length (EFL) of 200mm, making it suitable for a wide range of optical applications. This lens is sourced from Ross Optical, a reputable vendor known for their high-quality optical elements.

The lens is spherical in shape, with a base shape of a circle. It features two convex surfaces, denoted as R1 and R2, with radii of 205.04mm and -205.04mm respectively. This curvature allows for a high degree of light bending, making the lens ideal for use in imaging systems, beam shaping, and other applications where light needs to be focused or diverged.

The lens has a thickness of 2.9mm at the edge and 9.8mm at the center. This thickness, combined with the lens's material, contributes to its overall optical performance. The material ID for this lens is n-bk7 schott, a high-quality optical glass known for its excellent optical properties and durability.

The lens is designed to operate at a wavelength of 587.6nm. This wavelength falls within the visible light spectrum, making the lens suitable for use in applications involving visible light.

Notably, this lens is uncoated. While coatings can enhance the performance of optical elements by reducing reflections, increasing transmission, or providing other benefits, an uncoated lens can be advantageous in certain applications. For instance, uncoated lenses can be more cost-effective and are less susceptible to damage from environmental factors.
