32-705 15mm Dia. x 30mm FL Uncoated; Double-Convex Lens
The 32-705 is a high-quality spherical lens, boasting a double-convex design and a 15mm diameter. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for immediate purchase. The lens's base shape is circular, and it features an effective focal length (EFL) of 30mm, making it suitable for a wide range of optical applications.
The lens's geometry is meticulously crafted, with an edge thickness of 2.13mm and a center thickness of 4mm. The back focal length (BFL) is 28.82mm, and the radii of curvature for the first and second surfaces are 30.5mm and -30.5mm, respectively. The lens is made from the esteemed N-BK7 glass from Schott, ensuring excellent optical performance.
The lens is designed to operate at a wavelength of 587.6nm, and it is offered without any coating. This uncoated design can be beneficial in certain applications where a specific coating is not required or desired. However, users should be aware that uncoated lenses may have higher reflectivity and lower transmission compared to coated lenses.
