Working principle： Fluorescence is a kind of natural light emitting phenomenon. When using a beam of light substance, this substance can emit light with longer wavelength light and irradiation, the emitted light disappears. This is the longer wavelengths of light can emit fluorescence. The fluorescence substance known as fluorescent substances. Drop shot: the excitation light excitation principle with blue light (B light, a wavelength of 490nm) as an example, the light emitted from the DC lamp, the infrared filter and excitation filter, get the wavelength is about 490nm of the excitation light, the color spectroscope reflected into the objective, nature color spectroscope with reflection selectivity in a certain spectral region. Its characteristic is: can a certain wave length than totally reflects the light, the light of a certain wavelength longer than all through. According to this characteristic can be designed with the required excitation light color to adapt the spectroscope, making it the reflection wavelength below 490nm light. And let the light through the wavelength is greater than 490nm, this wavelength is about 490nm excitation light through color spectroscope, more than 490nm light through color spectroscope is removed, the excitation of the 490nm light through the lens assembly following fluorescence irradiates the fluorescent specimens On the specimens of the excited fluorescence wavelength is greater than 490nm (effective fluorescence wavelength is 525nm) by fluorescence imaging and color lens together, through the spectroscope (including a small amount of 490nm doping following excitation light is reflected back to the light source and not through) and filters (as all the light wavelength is less than 525nm), enter the observation and photography in the pure fluorescence beam.
