L-BCX022 20 mm Dia. Double-Convex Lens; EFL=31mm Uncoated
The L-BCX022 is a 20 mm diameter double-convex lens, boasting an effective focal length (EFL) of 31mm, sourced from the esteemed optical vendor, Ross Optical. This lens is a spherical type, specifically designed with a convex-convex base shape, ensuring a high level of optical precision.
The lens's geometry is meticulously crafted, with a 2mm edge thickness and a 5.3mm center thickness, providing a robust and durable structure. The radii of curvature are R1 = 31.11mm and R2 = -31.11mm, indicating a symmetrical design that contributes to minimal optical aberrations. The inner and outer radii are both zero, suggesting a uniform curvature throughout the lens.
The L-BCX022 is fabricated from the renowned N-BK7 Schott material, a borosilicate glass known for its excellent optical properties, including high transmittance and low dispersion. This material is ideal for applications that require high-quality imaging and minimal distortion.
The lens is designed for use with a wavelength of 587.6nm, making it suitable for a wide range of optical systems, including microscopy, beam shaping, and imaging applications. The lens is uncoated, offering a cost-effective solution for applications where anti-reflective coatings are not required.
