L-BCC073 30 mm Dia. Double-Concave Lens; EFL=-100mm Uncoated
The L-BCC073 is a 30 mm diameter Double-Concave Spherical Lens, featuring a negative focal length (EFL) of -100mm. This lens is sourced from Ross Optical, a reputable vendor known for their high-quality optical elements.
The lens's base shape is circular, with a thickness of 4.1mm at the edge and 2mm at the center. The inner and outer radii are both zero, indicating a symmetrical curvature. The radii of curvature for the first and second surfaces are -104.0538132mm and 104.0538132mm respectively, suggesting a strongly converging lens.
This lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The wavelength for this lens is 587.6nm, which is within the visible light spectrum.
Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their optical performance by reducing reflection, increasing transmission, or protecting the lens surface. However, this lens has been left uncoated, which may be desirable for certain applications where specific coating properties are not required.
