83-981 2 mm Dia. N-PSK53A/N-LASF9 Achromatic Doublet; EFL=12mm VIS-NIR 400-1000nm
The 83-981 is a high-quality achromatic doublet lens, designed and manufactured by Edmund Optics. This lens, with a 2 mm diameter, is specifically engineered for use in the visible (VIS) and near-infrared (NIR) spectrum, spanning from 400 to 1000nm.
The lens features an effective focal length (EFL) of 12mm, making it suitable for a wide range of optical applications. The achromatic design ensures that the lens effectively compensates for chromatic aberration, a common issue in lens systems where different wavelengths of light are focused at different points.
The lens is composed of two elements: N-PSK53A and N-LASF9, both from Schott, a renowned manufacturer of optical glass. This combination ensures high optical performance and durability.
The lens is coated with Edmund Optics' VIS-NIR coating (edm visnir0sp2002000), which is applied to both the front and back surfaces. This coating enhances the lens's transmission in the VIS-NIR range, reducing reflection and improving overall light transmission.
The lens has a center thickness of 1mm and an edge thickness of 1.91mm, providing a robust and stable platform for optical systems. The lens's geometry, including its inner and outer radii, is optimized for its specific application, ensuring high-quality imaging and light transmission.
