L-BCC025 50.8 mm Dia. Double-Concave Lens; EFL=-75mm Uncoated

The L-BCC025 is a 50.8 mm diameter Double-Concave Spherical Lens, featuring an Effective Focal Length (EFL) of -75mm, making it suitable for applications requiring strong negative magnification. Sourced from Ross Optical, this lens is uncoated, offering versatility in various light transmission environments.

The lens's geometry includes a 9.35mm edge thickness and a 2.5mm center thickness, ensuring robustness and precision. Its base shape is circular, providing consistent optical performance across the entire aperture. The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion, contributing to superior image quality.

The L-BCC025 is designed to operate at a wavelength of 587.6nm, aligning with the visible light spectrum's central wavelength. This makes it suitable for applications in fields like photography, cinematography, and other industries utilizing visible light.

Please note that this lens is uncoated, meaning it does not have any additional layers to enhance light transmission or protect the surface from environmental factors. This may result in reduced light transmission and increased susceptibility to damage, but it also provides flexibility in implementing custom coatings based on specific application requirements.
