Nissho Light Section Measuring Microscopes


Nissho.gif (3931 bytes)


Nissho Light Section Measuring Microscopes detect depths and heights with a non-contact optical method.  They detect the unevenness of surfaces without touching them using light rays, and are ideally suited for measurements in the range of 5 microns to 50 millimeters. 


bullet Micron Depth & Height Measuring Scope - HL Type (KY-90)
  • Projection slit light, reference slit light, and incident light are changed from tungsten lamp to durable halogen light source to ensure optimum illumination on the object surface for fatigue-free, precise measuring work.
  • The viewfield of object measuring surface covered by halogen light is widened and precision measuring work is possible by non-technical people without any special training.
  • Projection slit, vertical illumination and standard slit illumination are changed to the combination of halogen lamp and fiber optic guide.
  • The improvement in illumination and area create a fatigue-free measuring environment.
  • A large specimen table for large-size objects can be installed.

bullet High Micron Scope, Type 2 (HM-90-II-TV 2)
  • The High Micron Scope (Type 2), 0.1 m reading, produces a large increase in resolution using the light section method.  An industry-leading lateral expansion ratio of 4.5X (previous industry standard 1.4X) is achieved.
  • Exceptionally suitable for non-contact measurement of fine concave-convex surfaces.
  • An anti-vibration device ensures repeatability of reading and measuring operations and is provided as a standard specification.

bullet Micron XYZ Measuring Scope with Large Sliding Base (3DM-90)
  • The Micron XYZ Measuring Scope is a 3-dimensional measuring microscope for a wide range of applications.  It provides non-contact measurement of micro depth and height, employing the light section principle.  Also vertical and longitudinal measurement and microscopic observation can be performed.
  • Useful for quality control of large LCD plates.   Precise micro measurement work is possible for X, Y, and Z axes on the "MB2" type large sliding base.  Non-contact 3-dimensional measurement can be performed without difficulty by even a non-experienced operator using the TV monitor and XYZ axes electronic readout system.
  • It offers a large specimen table for large-sized measuring objects.

  • Accurate measurement performed by coinciding X, Y and Z axes with the measuring position on the built-in reference line.
  • Measured value is displayed digitally and units of 1 micron to millimeter can be used.
  • Observation of the measured surface can be performed on a video monitor.
  • Coincidence of measurement and observation makes it easy to operate and the operation extremely effective.
  • Various Z axes can be measured by numerous kinds of optical slits.
  • Non-contact precision optical measuring microscopes for micro linear dimension which provide easy and precise measurement based on "double focusing" system.
