A colorimeter used to adjust position using a reference light.

Abstract

The design of the aberration measuring device includes: a body in which a predefined area of ​​light is created and a receiving space connected to the opening is created; a light-receiving lens module is created at one end of the body to receive the measured light emitted from the measurement target; The measuring module is positioned behind the lens module that receives light in the receiving space to convert the light transferred from the lens module into an electrical signal, by bouncing and measuring color; and a light-emitting module to emit a reference light within the body and transmit the reference light to the measured target through a light-receiving lens module, where the reference light is displayed on the measured target at a position corresponding to the center of the opacity of the light-receiving lens module.
