L-BCC069 30 mm Dia. Double-Concave Lens; EFL=-150mm Uncoated
The L-BCC069 is a 30 mm diameter double-concave lens with a significant eccentricity, featuring an effective focal length (EFL) of -150mm. This lens is sourced from Ross Optical, a reputable vendor known for its high-quality optical elements.
The lens is designed with a base shape of a circle, and its geometry is characterized by a thickness of 3.4mm at the edge and 2mm at the center. The radii of curvature for the first and second surfaces are -155.6170715mm and 155.6170715mm, respectively. The lens does not have an inner or outer radius, indicating a uniform curvature across its surface.
The L-BCC069 is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This lens is specifically designed for use with a wavelength of 587.6nm. The lens's shape is spherical, and it does not come with any coating, which may affect its performance in certain applications.
This lens is a great choice for applications that require a strong negative lens with a high degree of curvature. However, its uncoated surface may make it less suitable for applications where high transmission or resistance to environmental factors is required.
