Optical moving platform detecting instrument

The utility model provides an optical movable platform detecting instrument, which is composed of a seat frame, an upright type sliding rail frame, a C-shaped suspension arm frame, optical detecting lenses and a bearing frame. The C-shaped suspension arm frame is in a structure with an opening; the optical detecting lenses are erected on the upper and the lower ends of the opening of the C-shaped suspension arm frame; the corresponding optical detecting lenses are focalized mutually and accurately. With the displacement between the upright type sliding rail frame and a sliding stopper of the seat frame, the C-shaped suspension arm frame can be positioned within the area range of a detected object and can perform a function of detecting completely in a type of X, Y axial direction displacement. The utility model has the advantages of high stability, large reduction of the volume of the detecting instrument, and capability of accurately and quickly detecting RGB, impedance, planeness, dimensional precision, etc. of optical glass, and the utility model can be used for detecting the hi-tech optical glass.
