- the filter unit 400 is for selectively transmitting only light sources of a specific area, has a cylindrical shape with a predetermined length, and has a second concave-convex portion 411 on the outer surface to prevent slipping when gripped by hand.
- a frame 410 and an optical filter 420 that selectively transmits only a light source having a wavelength of 405 to 410 nm are mounted on the filter frame 410 .
- the wavelength range of the light irradiated by the above-mentioned lamp 220 is rather widely distributed, that is, when the visible light of 400 ⁇ 700nm or the short wavelength corresponding to 400 ⁇ 450nm, the red color that is expressed during dental caries by blue or green It is difficult to accurately determine the existence of Of course, if a lamp that irradiates only a 405-410 nm wavelength range is used, it is easy to check the red color, but a lamp that irradiates only a specific wavelength range must be separately manufactured or purchased, and such a lamp is inevitably expensive.
- the filter unit 400 equipped with an optical filter 420 that selectively transmits only a light source of a wavelength of 405 to 410 nm, which is a specific wavelength range in which red fluorescence is clearly expressed is mounted on the lamp frame 210, irradiation Even if the wavelength band of the device is somewhat wide, it is possible to accurately check whether or not there is dental caries, thereby reducing manufacturing costs.
- the same effect can be expected even when light passing through only a specific wavelength band is transmitted to the visual cells.
- the first body 110 and the second body 120 are extended long so as to be comfortable to hold by hand, and then the connection terminal 320 is connected to the mobile phone while the filter unit 400 is mounted on the lamp frame 210. do.
- Light is irradiated by adjusting the light emitting member 200 toward the tooth, and at this time, it is visually confirmed whether there is a part where red fluorescence is expressed.
- the filter unit 400 is separated from the lamp frame 210, after bringing the filter unit 400 close to the eyes, it is checked whether red fluorescence is expressed through the filter unit 400.
- first flange 122 first uneven portion
- first fastener 214 second fastener
