33-925-INK 75 mm Dia. N-BAK1/N-SF8 Achromatic Doublet; EFL=150mm VIS-NIR 400-1000nm

The 33-925-INK is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 75 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 boasts an effective focal length (EFL) of 150mm, making it suitable for a wide range of optical applications. The achromatic design of this doublet lens ensures that chromatic aberration, the common issue of different colors of light focusing at different points, is minimized. This is achieved through the use of two different types of glass, N-BAK1 and N-SF8, each with unique refractive indices and dispersions.

The lens features a front and back coating of EDm VIS-NIR 0SP200-2000, a proprietary coating from Edmund Optics that enhances the lens's performance in the VIS-NIR spectrum. The lens has a center thickness of 23.2mm and an edge thickness of 36.01mm, providing robustness and durability.

The 33-925-INK is currently in stock and available for immediate purchase through the Edmund Optics website. With its superior design and high-quality construction, this lens is an excellent choice for any application requiring a high-performance, achromatic doublet lens in the VIS-NIR spectrum.
