49-340 18 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=30mm VIS-NIR 400-1000nm
The 49-340 is a high-quality achromatic doublet lens, boasting an 18 mm diameter and a focal length of 30 mm. This lens is designed for use in the visible to near-infrared spectrum, covering a wavelength range of 400-1000 nm.
The lens is composed of two elements: N-BAF10 and N-SF10, both from Schott, a renowned manufacturer of optical glass. These materials are known for their excellent optical properties, making them ideal for a wide range of applications.
The lens features a front and back coating of EDm VIS-NIR 0SP200-2000, a broadband anti-reflection coating that enhances transmission and reduces surface reflections. This coating is specifically designed for use in the visible to near-infrared spectrum, making it a perfect match for the lens's intended use.
The lens has a center thickness of 6.91 mm and an edge thickness of 6.55 mm. The inner and outer radii are 0 mm, indicating a simple, straightforward design. The lens's shape is circular, and it is classified as a multiplet due to its composition of multiple elements.
This lens is available from Edmund Optics, a leading supplier of optical components. According to the vendor's website, it is currently in stock, making it a readily available option for those in need of a high-quality achromatic doublet lens for use in the visible to near-infrared spectrum.
