  • Used to determine the type and degree of color perception in a color perception examination.
  • The abnormal quotient is digitally displayed with a single touch.
  • Both LEDs and interference filters are used for producing the color-mixture field (red and green) and monochromatic field (yellow). The wavelengths of the three colors, therefore, do not fluctuate even when moving the adjustment knob.
  • Due to the use of an LED light source, there is no increase in temperature.
  • Increases the reliability of color-mixture and monochromatic control due to the electric control of LED brightness without a complicated slit mechanism.
  • Color-mixture and monochromatic values are shown on the easy-to-read digital display, resulting in reduced reading errors.
  • *The Anomaloscope is a precision optical device. Errors in the measurement results may occur due the natural degradation of the optical system. Whether used or not, inspection and calibration are recommended once a year.
