Part is made up of diaphragm 4, optical filter 5, spacer ring 6 and trim ring 7.Diaphragm 4 is fixed on the through hole 16 of pipe box main body 3, can control
The size of window, diaphragm opening size may be configured as 4mm*9.5mm, can at optical system image planes control visual field.Described
Optical filter 5 embeds in the groove that diaphragm 4 is provided with, and is used for controlling incident illumination wave band, ends unwanted wave band.At the present embodiment
In, optical filter is barium fluoride crystal, can end the DUV of below 130nm, coordinates photomultiplier tube blind type photoelectricity cloudy
Pole, dedicated probe VUV wave band, the bore of optical filter is designed as Φ 16mm, and its thickness is 0.5mm, thus is easily broken.
Described spacer ring 6 is covered in the outer surface edge of optical filter 5, and extrudes spacer ring 6 by trim ring 7, and whole optical filter box is solid
On the through hole 16 of pipe box main body 3.The material of spacer ring is politef, less than the hardness of metal, it is to avoid itself and optical filter
Firmly meet place.After using spacer ring 6 and trim ring 7 to fix, suitable regulating load size, it is ensured that optical filter 5 can bear bigger
Vibration.
Described vibration damping interlayer includes rectangular teeth damping body 10 and boss vibration-damping sheet 8, for providing soft for pipe box and overcoat
Property connect.Rectangular teeth damping body 10 is rectangular recess, is conducive to location, it is to avoid tilt and rotate.Described pipe box is nested in
In groove；Described boss vibration-damping sheet 8 is covered on the port of groove, as it is shown on figure 3, in boss vibration-damping sheet 8 and pipe box main body
Contact surface on be evenly distributed with four boss 20, it is to avoid optical filter box contacts with boss vibration-damping sheet 8, improves boss simultaneously
The elasticity of vibration-damping sheet 8.This boss vibration-damping sheet 8 offers the through hole 16 relative with photomultiplier transit window of tube.
As shown in Figure 4, the outer surface of described rectangular teeth damping body is evenly distributed with some rectangular teeths 19.Rectangle damping body
Rectangular teeth 19 can be that vibration damping interlayer deformation provides space, and changes rectangle by the width and aspect ratio changing rectangular teeth 19
