The 49-795 is a high-quality achromatic doublet lens, boasting a 25.4 mm diameter and an effective focal length (EFL) of 88.9mm. This lens is specifically designed for use in the visible to near-infrared spectrum, covering the wavelength range of 400-1000nm.
The lens is composed of two elements, made from N-BAK1 and N-SF8 Schott glass. These materials are renowned for their excellent optical properties, contributing to the lens's high performance. The lens features a robust design, with a thickness of 8.07mm at the edge and 6mm at the center. The inner and outer radii are 0mm, indicating a symmetrical design.
The 49-795 lens comes with a broadband anti-reflection coating, specifically the EDM VIS-NIR 0SP2002000 coating. This coating is applied to both the front and back surfaces of the lens, reducing surface reflections and improving light transmission.
The lens is sourced from Edmund Optics, a leading manufacturer of optical components. According to the vendor's information, the lens is currently in stock and available for immediate purchase.
