mscopetypes

It is possible to choose best objective lens for measurement object from wide variation of lens lineup such as normal type, NIR type, high resolution type, long W.D. type, etc.

For visible spectral range, M-Plan Apo series objective lenses are recommended, which has a super working distance design.

For NIR spectral range, M-Plan Apo NIR objective lenses are recommended, which has excellent wavelength transmittance in near-infrared spectral range and has chromatic aberration correction in the 480-1800nm region.

You can also select M-Plan Apo HR objective lenses, a high-resolution objective lens with excellent optical resolution and numerical aperture.

  • Pixel Resolution：calculated value by (View)/(Number of effective pixels), means length equivalent to 1pixel of image sensor.
  • In case of using 2x intermediate lens option (for NFP measurement optics M-Scope type S), these values are calculated as equivalent to using double of objective lens magnification.
