L-BCC108 50 mm Dia. Double-Concave Lens; EFL=-100mm Uncoated

The L-BCC108 is a 50 mm diameter Double-Concave Spherical Lens, offering a negative focal length (EFL) of -100mm. This lens is sourced from Ross Optical, a reputable vendor in the optical industry. The lens is uncoated, providing a basic optical surface that does not include any additional layers for reflection or transmission control.

The lens features a base shape of a circle and is designed with two concave surfaces. The first surface has a radius of curvature (R1) of -104.6887515, while the second surface has a radius of curvature (R2) of 104.6887515. The center thickness of the lens measures 2mm, while the edge thickness is 7.9mm, providing a robust structure for various applications.

The lens material is n-BK7 Schott, a high-quality optical glass known for its excellent transmission properties and low auto-fluorescence. The material is suitable for use in the visible spectrum, specifically designed for a wavelength of 587.6nm.

This lens is an ideal choice for applications requiring a negative focal length and a high-quality optical material. Its double-concave design and uncoated surface make it suitable for use in various setups, such as beam expansion, image reduction, or correcting aberrations in optical systems.
