Embodiment 1
[0028] Embodiment 1: see figure 1 , figure 2 , an X-ray collimator device, comprising a base 6, characterized in that: a fixedly connected slit body 1 is set on the base 6, and a straight slit 2 is set in the slit body 1.
[0029] The above-mentioned slit 2 is a rectangular slit.
[0030] The above-mentioned slit main body 1 is interlacedly fastened by the inner fastening surface 10 and the outer fastening surface 11 of the overall L-shaped upper fastener 1-1 and the lower fastener 1-2 along the direction of the optical path, and is positioned at both ends. The pin 4 and the positioning screw 5 are fixedly formed, and its shape is a cuboid; the slit 2 is between the inner surface 9 of the upper fastener 1-1 and the lower fastener 1-2 and the inner fastening surface 10 gap between.
[0031] The center line of the slit 2 is located at the center of the slit body 1 .
[0032] A boss 3 is provided at one end of the above-mentioned slit main body 1, and the boss 3 is composed ...
Embodiment 2
[0034] Example 2: see image 3 , Figure 4The structure difference between this embodiment and embodiment 1 is that: the inner fastening surface 10 and the outer fastening surface 11 of the upper fastener 1-1 and the lower fastener 1-2 are along the The concave-convex stepped surface with mutually matched optical path directions has two concave-convex fastening surfaces.
[0035] Other structures are the same as in Embodiment 1.
Embodiment 3
[0036] Embodiment 3: see Fig. 5, Figure 6 , the structure difference between this embodiment and embodiment 1 is: the slit 2 is a cylindrical circular hole slit; the slit body 1 is composed of an integral rectangular upper fastener 1-1 and a lower fastener 1-2 is buckled along the direction of the light path, and is fixed by positioning pins 4 and positioning screws 5 at both ends, and its shape is a cuboid; the slit 2 is composed of the upper fastener 1-1 and the The lower fastener 1-2 is formed by fastening the corresponding semicircular arc surface on the fastening surface. The fastening surface of the upper fastener 1-1 and the lower fastener 1-2 is a concave-convex stepped surface that cooperates with each other along the optical path direction, the number of the concave-convex fastening surface is one, and the concave-convex stepped surface The height is greater than the radius of the circular hole slit, and an opening is arranged on the convex step surface above the s...
