49-395 50 mm Dia. N-BAK4/N-SF10 Achromatic Doublet; EFL=350mm VIS-NIR 400-1000nm

The 49-395 is a high-quality achromatic doublet lens, boasting a 50 mm diameter and a focal length of 350 mm, specifically designed for the visual and near-infrared spectrum (VIS-NIR) range of 400-1000 nm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is a multiplet type, ensuring superior image quality and minimal chromatic aberration.

The lens is crafted from two types of Schott glass, N-BAK4 and N-SF10, which are known for their excellent optical properties. The front and back surfaces of the lens are coated with the advanced EDM VISNIR0SP2002000 coating, providing enhanced durability and improved light transmission across the specified wavelength range.

The geometry of the lens is meticulously designed, with an edge thickness of 10.07 mm and a center thickness of 8 mm. The lens also features a central thickness 'a' of 4 mm, providing additional design flexibility. The inner and outer radii are 0, indicating a circular shape.

This lens is an ideal choice for applications that require high-resolution imaging in the VIS-NIR spectrum, such as scientific research, machine vision, and biomedical imaging. With its robust construction, advanced coatings, and superior optical performance, the 49-395 is a reliable and versatile addition to any optical system.
