BICC-25.4-154.9-UV 25.4 mm Dia. UVFS Laser Grade Concave-Concave Lens; EFL=-150mm Uncoated

This is the BICC-25.4-154.9-UV, a laser grade concave-concave spherical lens, sourced from CVI Laser Optics. The lens has a diameter of 25.4 mm and a center thickness of 3.2 mm. The lens's design features two concave surfaces with radii of curvature of -154.9 mm and 154.9 mm, respectively. The effective focal length (EFL) of this lens is -150 mm, making it a negative lens.

The lens is made of UVFS material with the Mal-1965 index. This material is particularly suitable for use in ultraviolet applications due to its high transmittance in this region. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, the lens's surface quality is still maintained at a high level, ensuring optimal performance in its intended application.

The lens is designed to operate at a wavelength of 587.6 nm. This wavelength falls within the visible light spectrum, specifically in the yellow-green region. This makes the lens suitable for applications that require precise manipulation of light in the visible spectrum, such as in laser systems, spectroscopy, and imaging systems.
