49-371-INK 30 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=50mm VIS-NIR 400-1000nm

The 49-371-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 30 mm, is designed for use in the visible (VIS) and near-infrared (NIR) spectrum, specifically catering to the wavelength range of 400-1000nm.

The lens features a focal length (EFL) of 50mm, making it suitable for a wide range of optical applications. The achromatic design of the lens ensures that it effectively minimizes chromatic aberration, a common issue in lens systems where different wavelengths of light are focused at different points.

The lens is composed of two types of glass, N-BAF10 and N-SF10, both from Schott, a leading manufacturer of high-quality optical glass. This combination of materials ensures excellent optical performance.

The lens is coated with EDm VIS-NIR 0SP2002000, a proprietary coating from Edmund Optics that enhances the lens's performance in the VIS-NIR spectrum. This coating reduces surface reflections, thereby increasing transmission and improving overall image quality.

The lens has a thickness of 9.25mm at the edge and 11mm at the center, with an inner radius of 0mm and an outer radius of 0mm. The center thickness 'a' is 2.2mm. The lens's geometry is designed to provide superior optical performance while maintaining a compact form factor.
