The 49-765 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is specifically designed for use in the 400-700nm wavelength range, making it suitable for a wide range of optical applications.
The lens features a 25.4mm diameter and an effective focal length (EFL) of 38.1mm, providing a compact yet powerful optical solution. The doublet design is composed of two elements, N-BAF10 and N-SF6, both from Schott, ensuring superior optical performance.
The lens surfaces are coated with Edmund Optics' standard MgF2 coating, which is applied to both the front and back surfaces. This coating enhances the lens's light transmission capabilities and provides excellent protection against environmental factors.
The geometry of the lens is meticulously designed, with a center thickness of 10.5mm and edge thickness of 9.44mm. The lens also features three radii (r1, r2, and r3) that contribute to its excellent optical performance. The lens is circular in shape, providing a wide field of view and making it compatible with various optical systems.
