The present invention provides a color meter using a color difference meter module having a collimator lens and a condensing lens. The color meter includes: a case in which a light receiving space is prepared; a light entering lens module which includes multiple lenses arranged serially from one side of the case to the inside of the case, is placed on an area where light from a measurement target enters, and delivers the light to the inside; and a color difference meter module. The color difference meter module includes: a color filter which is installed in the light receiving space, receives light passing through the light entering lens module, and passes light of a certain wavelength only; a photodiode which receives the light passing through the color filter and converts the received light into an electrical signal; a collimator lens which is placed on a light path between the light entering lens module and the color filter, passes the light passing through the light entering lens module in parallel and delivers the light to the color filter; and a condensing lens which condenses the light passing through the color filter between the color filter and the photodiode and delivers the condensed light to the photodiode. |
