83-338 2 mm Dia. N-PSK53A/N-LASF9 Achromatic Doublet; EFL=9mm MgF2 400-700nm
The 83-338 is a high-quality achromatic doublet lens from Edmund Optics, designed with a 2 mm diameter and a focal length of 9mm. This lens is a multiplet, meaning it is composed of multiple optical elements to achieve superior performance.
The lens is constructed from two types of Schott glass, N-PSK53A and N-LASF9, which are renowned for their optical properties. The N-PSK53A is used for the first element, while the N-LASF9 is used for the second. This combination helps to minimize chromatic aberration, a common issue in optical systems where different wavelengths of light are focused at different points.
The lens features a standard MgF2 coating on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, particularly in the 400-700nm range. The center thickness of the lens is 1mm, while the edge thickness is 1.88mm. The lens has a clear aperture, with both the inner and outer radii being 0.
The 83-338 is available from Edmund Optics and is currently in stock. It is a versatile lens that can be used in a wide range of applications, making it a valuable addition to any optical system.
