Shape is coincide, and the height shown on height adjuster on adjustment frame at this time is recorded, and then appropriate hoisting depth is to adjust angle to stay
Space out.Then the angle that eyeglass is adjusted with adjustment frame, makes laser export laser.Laser is in the shape of hysteroscope to be glued at this time
State (as shown in Figure 2)；The viscose glues such as epoxy glue or ultraviolet glue are finally coated in the gap between eyeglass and microscope base and reduce hysteroscope height
To the position recorded just now.Determine that laser output is normal again；
Step 2: it will be seen that light laser (as shown in 8 in Fig. 2) is integrally attached to laser after being fixed in matched tooling
On device optical axis at 1~2m of distance, the instruction luminous energy for launching it is in angular illumination to cavity mirror face of near vertical；It finds
The instruction light of hysteroscope reflection simultaneously projects it on screen (as shown in 7 in Fig. 2), and screen is fixed on optical platform and is recorded
Light spot position；For having the spherical mirror of certain curvature, visible laser, alignment cavity can be substituted with tunable telescope
Its internal light source is opened after mirror and adjusts its focal length and clearly returns to picture until being observed that, reads and the position for recording picture is carved
Then degree waits viscose glue solidification to mark its normal to be directed toward；
Step 3: viscose glue, which is fully cured, generally will appear small deformation afterwards hysteroscope is caused slight rotation occur, at this time
It copes with and is bonded the position of front and back reflected light than hysteroscope to learn direction and the degree of deflection；
Step 4: detuning by hysteroscope shown in Fig. 2 is for increasing because of the elevation angle, and the position of reflection light point is higher than label at this time
