Abstract
The utility model relates to a quick adjusting spectrometer experimental apparatus. The apparatus consists of a spectrometer telescope, a laser diode light source, an light emitting diode light source, a viewing screen and a reflector, wherein the laser diode light source or the light emitting diode light source is connected with the spectrometer telescope; the viewing screen sleeves on the spectrometer telescope; and the reflector is parallel to the viewing screen, perpendicular to the spectrometer telescope, and is disposed at the front end of the object lens of the telescope. In an experiment, the laser diode serves as the light source, a user observes with eyes at the side of a cross-hair reticle of the viewing screen. The light path trip of an apparatus composed as such is that the light emitted by the laser diode is refracted through a small right angle trapezoid prism at the upper end of the light source, and then is refracted and irradiated by the object lens of the spectrometer telescope and to the reflector, and the reflector reflects the light to the position where the cross-hair reticle of the viewing screen is positioned. By this time, the user can directly view relative phenomena and perform adjustment for specific purposes. Once the adjustment meets the requirement, the light emitting diode serves as the light source, and the user can view and adjust through the spectrometer telescope, and only little fine adjustment is needed. As a result, the adjustment is quick and efficient. The quick adjusting spectrometer experimental apparatus is suitable for relative experiments of spectrometers for institutions of higher learning in science of engineering.
