49-936 6.25 mm Dia. N-BAF10/N-SF57 Achromatic Doublet; EFL=7.5mm VIS 0° 425-675nm
The 49-936 is a high-quality achromatic doublet lens, boasting a 6.25 mm diameter and an effective focal length (EFL) of 7.5 mm. This lens is designed for use within the visible light spectrum, specifically between 425 and 675 nm.
The lens is composed of two types of glass, N-BAF10 and N-SF57, both from the reputable Schott brand. This combination helps to correct chromatic aberration, a common issue in optics where different wavelengths of light are focused at different points.
The lens features a standard coating on both the front and back surfaces, specifically the EDM VIS-0 STD CURVE coating. This coating enhances the lens's performance by reducing surface reflections and improving transmission.
The geometry of the lens is carefully designed with a center thickness of 5 mm and an edge thickness of 4.61 mm. The lens also features three radii of curvature: r1 at 5.6 mm, r2 at -3.71 mm, and r3 at -11.34 mm. These parameters contribute to the lens's overall optical performance.
The lens is available from Edmund Optics, a leading supplier of optical components. According to the vendor's information, the lens is currently in stock, ensuring quick delivery for your optical projects.
