L-BCC068 25.4 mm Dia. Double-Concave Lens; EFL=-200mm Uncoated
The L-BCC068 is a 25.4 mm diameter Double-Concave Spherical Lens, sourced from the renowned optical component vendor, Ross Optical. This lens is designed for use in systems where a negative focal length is required, with an Effective Focal Length (EFL) of -200mm.
The lens is fabricated from N-BK7 Schott glass, a popular choice due to its excellent optical properties and broad transmission range. The lens's geometry features a double-concave design, with a center thickness of 2.5mm and an edge thickness of 3.13mm. This design results in a high degree of curvature, which is beneficial for applications requiring strong dispersion or refraction.
The lens's base shape is circular, making it suitable for use in a wide range of optical systems. Notably, the lens does not have any coating, which may make it suitable for applications where anti-reflective properties are not required or desired.
The lens's design wavelength is 587.6nm, which is within the visible light spectrum. This makes the lens suitable for use in systems where visual observation or imaging is required.
