置。A plurality of light beams are extracted from a light source that emits a continuous spectrum, and these light beams are passed through interference filters placed on each optical axis to become monochromatic light with a predetermined wavelength.
By transmitting these monochromatic lights through variable entrance slits and optical systems arranged on their respective axes, and changing the width of the entrance slits, each monochromatic light can be produced as monochromatic light with variable brightness or a mixed ratio. A color blindness testing device characterized in that variable mixed color light is handled adjacently within the same field of view, and color matching is performed by observing the hue of each converged color light.
