32-936 20.0mm Dia. x 70.0mm FL; Uncoated; Plano-Convex Lens
The 32-936 is a 20.0mm diameter, 70.0mm focal length Plano-Convex lens, sourced from the renowned optical components vendor, Edmund Optics. This lens, designed for general-purpose use, is uncoated, offering users a cost-effective solution for various applications.
The lens's geometry features a 1.59mm edge thickness and a 3mm center thickness, with a 36.18mm radius of curvature on the convex side. The lens's effective focal length (EFL) is 70mm, and the back focal length (BFL) measures 68.03mm. The lens's design is circular, with no inner or outer radius specified, indicating a uniform curvature throughout.
The lens is crafted from the high-quality N-BK7 glass from Schott, a material known for its excellent optical properties, including a high Abbe number and low dispersion. The lens is optimized for a wavelength of 587.6nm, making it suitable for applications in the yellow-green part of the visible light spectrum.
Despite being uncoated, this lens can still deliver high-quality optical performance, making it a versatile choice for various applications. However, users should note that uncoated lenses may be more susceptible to surface reflections and may not perform as well in harsh environmental conditions compared to coated lenses.
