Multiple wavelength digital refractometer for dispersion measurements.
The digital, fully automatic spectral refractometer ATR-L consists of an electronic unit separated from the stainless steel measuring unit. Dispersion measurement at 7 wavelengths over the full visible range. A sample volume of 0,3 ml is sufficient for measuring. The refractometer is equipped with a Peltier thermostat (no external water bath/thermostat necessary).
The digital multiple wavelength refractometer of SCHMIDT + HAENSCH is based on CCD-sensor detection of the critical angle of total reflection. This is done sequentially for all LEDs (colours) and displayed as refractive indices according to these wavelengths. SCHMIDT + HAENSCH has the necessary data basis for calibration of such an instrument through research work performed at its premises in Berlin.
- High-precision refractometer
