L-BCC114 50 mm Dia. Double-Concave Lens; EFL=-400mm Uncoated

The L-BCC114 is a 50 mm diameter Double-Concave Spherical Lens, sourced from the renowned optical vendor, Ross Optical. This lens is designed for use in systems where a negative focal length is required. The lens's base shape is circular, ensuring consistent performance across its entire surface.

The lens's geometry is characterized by its double-concave structure, with an inner radius of 0 mm and an outer radius of 0 mm. The center thickness of the lens is 2.5 mm, while the edge thickness is 4.1 mm, providing robustness and durability. The effective focal length (EFL) of this lens is -400 mm, making it suitable for applications that require a strong converging or diverging effect.

The L-BCC114 lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This material ensures high transmission in the visible spectrum, making it ideal for a wide range of applications. The lens is uncoated, offering bare glass performance. However, users can request custom coatings to enhance the lens's performance in specific applications.

This lens is designed to work with a wavelength of 587.6 nm, typically used in monochromatic light sources. It's important to note that the lens's performance can vary with different wavelengths, so users should consider this when selecting a lens for their application.
