BICV001 6 mm Dia. x -15 mm FL; Uncoated; Double-Concave Lens

The BICV001 is a high-precision double-concave lens, sourced from the reputable vendor WTS Photonics. This lens boasts a 6 mm diameter and a center thickness of 1.5 mm, with an edge thickness of 2.1 mm, providing a robust and compact design. The lens features a base shape of a circle, making it suitable for a wide range of applications.

The lens's geometry is characterized by its double-concave structure, with radii of curvature R1 and R2 at -15.2 mm and 15.2 mm, respectively. This design results in a back focal length (BFL) of 14.3 mm and an effective focal length (EFL) of -15 mm, making it ideal for applications requiring strong negative dispersion.

The lens is crafted from the renowned material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including high transparency and low dispersion. This material is particularly suitable for applications in the visible spectrum, as demonstrated by the lens's specified wavelength of 546.1 nm.

Notably, this lens is uncoated, offering users the flexibility to apply their preferred coating based on their specific application requirements. However, users should be aware that uncoated lenses may be more susceptible to surface reflections and scratching.
