In order to acquire clear images capable of diagnosing cracked tooth by light transmission, the optical properties of LED light source were examined. Based on the results, the prototype which basically consisted of LED light source, bandpass filter and commercial compact camera module was designed and manufactured. The wavelength and optical power of the LED in the prototype were 850 nm and 7 mW/Sr, respectively. In evaluation of the prototype using microscope, the observation of the crack with width of above $17{\mu}m$ was possible. In addition, image analysis to obtain shape information on the observed tooth cracks was carried out.
