L-BCC046 22.4 mm Dia. Double-Concave Lens; EFL=-40mm Uncoated
The L-BCC046 is a 22.4 mm diameter Double-Concave Spherical Lens, sourced from the renowned optical vendor, Ross Optical. This lens, designed for use in spherical applications, boasts a base shape of circular geometry, contributing to its versatility in various optical systems.
The lens's geometry is characterized by its significant thickness at the edge, measuring 4.9 mm, and a reduced thickness at the center, measuring 2 mm. This design, coupled with its double-concave shape, results in an effective focal length (EFL) of -40 mm, making it suitable for applications requiring strong negative dispersion.
The L-BCC046 is fabricated from the high-quality material, N-BK7 Schott, a borosilicate glass known for its excellent optical properties and durability. The lens is designed to operate at a wavelength of 587.6 nm, making it suitable for use in a wide range of optical systems.
Notably, this lens is uncoated, offering users the flexibility to apply their preferred coating based on their specific application requirements. However, it's essential to consider that uncoated lenses may be more susceptible to surface reflections and scattering, which could impact the overall performance of the optical system.
