33-921 75 mm Dia. N-BAF10/N-SF57 Achromatic Doublet; EFL=100mm VIS 0° 425-675nm

The 33-921 is a high-quality achromatic doublet lens, boasting a 75 mm diameter and an effective focal length (EFL) of 100 mm, specifically designed for the visible light spectrum ranging from 425 to 675 nm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is available for purchase through their official website.

The lens is constructed from two types of Schott glass, N-BAF10 and N-SF57, which are carefully selected to minimize chromatic aberration, a common issue in lens systems. The front and back surfaces of the lens are coated with the EDM VIS-0 standard curve coating, enhancing its light transmission capabilities and overall performance.

The lens geometry is meticulously designed, with an inner radius of 0 mm, an outer radius of 0 mm, and a central thickness of 26 mm. The edge thickness measures 24.66 mm, while the central thickness of the first element (r1) is 66.67 mm and that of the second element (r2) is -66.67 mm. The third radius (r3) is -343.59 mm.

This lens is a multiplet, meaning it is composed of multiple elements, and it has a base shape that is circular. The lens is currently in stock and available for immediate purchase, making it an ideal choice for users in need of a reliable and high-performing optical component.
