L-BCC063 25.4 mm Dia. Double-Concave Lens; EFL=-25mm Uncoated

The L-BCC063 is a 25.4 mm diameter Double-Concave Spherical Lens, sourced from the renowned optical component vendor, Ross Optical. This lens boasts an effective focal length (EFL) of -25mm, making it suitable for applications that require strong negative dispersion.

The lens's geometry is characterized by its base shape, which is circular, and its thickness at the edge, which measures 7.73mm. The center thickness is significantly less at 2.5mm, contributing to its double-concave design. The inner and outer radii are both 0, indicating a symmetrical curvature.

The L-BCC063 is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This makes it an ideal choice for applications that require high optical performance and precision. The lens is designed to work with a wavelength of 587.6nm, which is within the visible light spectrum.

Notably, this lens does not come with any coating, as indicated in the item data. Coatings are often applied to lenses to enhance their performance by reducing reflection, increasing transmission, or providing protection against environmental factors. However, the uncoated nature of this lens could be advantageous in certain applications where specific coating properties are not required.
