84-330 6.25 mm Dia. N-FK5/F2HT Achromatic Doublet; EFL=25mm UV-VIS 345-700nm

The 84-330 is a high-quality Achromatic Doublet lens, boasting a 6.25 mm diameter and an effective focal length (EFL) of 25mm. This lens is specifically designed for use within the UV-VIS spectrum, spanning from 345 to 700nm, making it an ideal choice for applications requiring precise optical performance within this range.

The lens is composed of two elements: N-FK5 from Schott and F2HT from Schott. Both elements are coated with Edmund Optics' standard UV-VIS coating, ensuring optimal transmission and protection against environmental factors. The first element has a radius of curvature (R1) of 13.57, while the second element has an R2 of -13.57 and an R3 of -43.89. The lens has a thickness of 2.52mm at the edge and 2mm at the center, with an additional 1mm thickness at the center a.

This lens is a multiplet, meaning it is composed of multiple elements to correct optical aberrations and improve image quality. The base shape is circular, ensuring uniformity and consistency in optical performance. The lens's geometry is designed to provide excellent performance in a compact and efficient package.
