Abstract:
A microscopic image apparatus for converting infrared light into visible light, comprising:a sample stage for accommodating a sample; an infrared source outputting first infrared light to the sample, the first infrared light penetrating the sample to create second infrared light having infrared absorption spectrum information of the sample; an object lens for converting infrared light into visible light having an optical crystal and an infrared object lens, wherein the infrared object lens receives the second infrared light having infrared absorption spectrum information of the sample and converts the second infrared light into parallel infrared light to enter the optical crystal; a visible light source outputting narrow band visible light to the optical crystal, wherein, in the optical crystal, the narrow band visible light and the second infrared light having infrared absorption spectrum information of the sample are coupled into sum-frequency light having a visible sum-frequency image; a visible light imaging lens projecting the visible sum-frequency image on a predetermined position; and a visible light image capturing device disposed on the position to receive the visible sum-frequency image.
