KPR-2000

The sales of KPR-2000 is discontinued in June, 2015.

Features

Minute sample size (3 dia. x 1t mm) can be measured
  • Just load a sample and press the Start button. Automatic measurement starts at the preset conditions by the personal computer that displays the measured data at once.
  • Automatic photoelectric detection and computerized control achieve high accuracy and repeatability.
  • Measurement at three wavelengths in just one minute.
  • The Energy distribution graph is useful to estimate the existence of double refraction.
  • The use of a refractive liquid between the sample and the V-block prism makes it possible to measure the sample with frosted surface if the two faces are machined to 90-degree.
  • Easy operation by the mouth to select measuring parameter.
  • Up to ten wavelengths can be added, allowing the operator to select the required wavelength easily.(Note.1)

Note1:Some wavelength combinations may be unavailable.

Applications

Refractive index measurements for transparent liquids and transparent samples such as new materials and glass. Birefringence presumption.

Operation Screens

The Windows-based graphical control software offers easy understanding of operations. Exporting data to commercial spreadsheet software is ideal for various reporting.

Extensive Options
