3.33X / F1.9

Industrial Lens Optimized for 16k VT Series (M95)


Optimized for 16k & 23k VT Series (M95) and High Resolution Area Scan Cameras

Precisely designed for Vieworks cameras, VEO JK Series achieves best image quality when used with Vieworks TDI line scan cameras VT Series (M95) and high resolution area scan cameras. These non-coaxial lenses guarantee superior image quality.


High Magnification Lens with Exceptional Performance

VEO_JK DIAMOND 3.33X / F1.9 is a high magnification lens that performs best at a magnification of 3.33x and an aperture of F/1.9. 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 (250 LP/mm on the object plane). When used with VT Series (M95), a resolution of 1.5 ㎛ per pixel is achieved.

  • *Image 1200% enlarged
  • *Transmitted light illumination used
  • *Vieworks VERI-PANEL used

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.
