49-334 15 mm Dia. S-BAH11/N-SF10 Achromatic Doublet; EFL=25mm VIS-NIR 400-1000nm

The 49-334 is a high-quality achromatic doublet lens, designed and manufactured by Edmund Optics. This lens, with a diameter of 15 mm and a focal length of 25 mm, is specifically engineered for use in the visible to near-infrared spectrum, spanning from 400 to 1000 nm.

The lens is composed of two elements: S-BAH11 from Ohara and N-SF10 from Schott. These materials are carefully selected for their optical properties, contributing to the lens's overall performance. The lens features a sophisticated geometry, with radii of curvature of 17.97 mm, -11.2 mm, and -85.31 mm, and a central thickness of 6.27 mm. The edge thickness is 6.06 mm, while the thickness at the first air-glass interface is 1.76 mm.

The lens is coated with Edmund Optics' VIS-NIR coating (edm visnir0sp2002000) on both the front and back surfaces. This coating enhances the lens's transmission and reduces reflection, thereby improving its light-gathering capability and overall performance in the specified wavelength range.

The 49-334 is currently in stock and available for immediate purchase through the Edmund Optics website. With its superior optical properties and robust construction, this lens is an excellent choice for a wide range of applications in the fields of imaging, metrology, and spectroscopy.
