High Magnification Lens with Exceptional Performance

VEO_JK DIAMOND 2.5X / F2.6 is a high magnification lens that performs best at a magnification of 2.5x and an aperture of F/2.6. Chromatic aberration is minimal and best performance is maintained even when the spatial frequency reaches as high as 72 LP/mm on the image plane (180 LP/mm on the object plane). When used with VT Series (M95), a resolution of 2.0 ㎛ per pixel is achieved.

Minimal Variance of MTF Over Entire Field of View

VEO JK Series achieves over 30% contrast at 72 LP/mm frequency on the image plane. With remarkably low variance of modulation transfer function (MTF) over the entire field of view (FoV), amounting to 7%, these lenses demonstrate uniform and stable performance.

*Depending on the VERI-PANEL and the optical component for illumination used in testing, results may show slight variations.
