The 35-995 is a high-quality achromatic doublet lens, boasting a 9 mm diameter and a focal length of 36 mm, specifically designed for UV-VIS applications within the 345-700 nm range. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available directly from their website.
The lens is constructed from two types of Schott glass: N-FK5 for the first element and F2HT for the second. This combination helps to minimize chromatic aberration, ensuring sharp and clear images. The lens features a standard UV-VIS coating on both the front and back surfaces, further enhancing its performance and durability.
The geometry of the lens is meticulously designed, with an inner radius of 0 mm, an outer radius of 0 mm, and a thickness at the edge of 3.79 mm. The first radius of curvature (r1) is 19.2 mm, while the second (r2) is -16.29 mm, and the third (r3) is -57.12 mm. The center thickness is 3 mm, with a reduced thickness of 1.5 mm at the center a.
This lens is a multiplet, meaning it is composed of multiple elements, and its base shape is circular. It is available in stock and ready for immediate use in your optical system.
