Specifically, the step glass includes a rectangular first glass 14 and a rectangular second glass 15, where the first glass 14 is overlapped on the second glass 15, i.e. the top surface of the second glass 15 contacts with the bottom surface of the first glass 14, the length of the first glass 14 is smaller than that of the second glass 15, and the width of the first glass 14 is also smaller than that of the second glass 15, so that the bottom surface of the second glass 15 is the bottom surface 12 of the step glass, the top surface of the first glass 14 is the top surface 11 of the step glass, and the top surface of the second glass 15 that is not covered by the first glass 14 forms a step surface 13.

The inventor explores a plurality of technical schemes of putting the micro lens array into the detector through a plurality of researches and experiments, but as the detection surface of the detector is provided with the protective glass 1, the interior of the protective glass is provided with the signal wire 6 and the two-dimensional imaging device, the signal wire 6 occupies a certain space height, and the focal length of the micro lens is usually smaller due to the limitation of the size, so that the problems of supporting and touching the signal wire of the micro lens array are also solved when the photosensitive surface 4 of the detector is accurately coupled at the focal length of the micro lens array 3. Finally, the inventor proposes a solution in this embodiment by repeatedly designing and testing, designing the protection glass as a step glass, and engraving the microlens array on the step glass, so that the problem of supporting the microlens array, the problem of touching the signal line and the problem of coupling the microlens array with the photosensitive surface can be solved simultaneously when the protection glass is mounted on the detector, and an effect of 1+1 being greater than 2 is produced.
