Description
Technical field
The invention belongs to optical element measuring technology, it is related to a kind of servo-actuated speculum resolution test device and test system
Background technology
Under normal conditions, it is the loading that will be tested servo-actuated speculum 3 and be placed on optical bench to be servo-actuated speculum resolution measurement
On platform, the image from two meters of 4 intrinsic resolution plates of parallel light tube is observed using 1 meter of preset lens 5.Because being servo-actuated speculum 3 in loading
Placement location is not fixed on platform, the position for constantly adjusting servo-actuated speculum 3 is needed, to find resolution ratio in preset lens
Picture, it is therefore desirable to which two people's cooperations could carry out a people and are imaged by preposition sem observation, and another people need to not stop to adjust on objective table
The position of servo-actuated speculum, working efficiency is not high, and easily injuring part.Under normal circumstances, a servo-actuated speculum point is completed
The measurement of resolution needs to work in double harness 30 minutes.
Invention content
Technical problems to be solved
In order to avoid the shortcomings of the prior art, a kind of servo-actuated speculum resolution test device of present invention proposition and survey
Test system, while substantially reducing the working time so that in entire test process in addition to initial workpiece, can be completed by a people, to carry
The working efficiency of high tester.
Technical solution
A kind of test device of servo-actuated speculum resolution ratio, it is characterised in that including fixed block 2, two-dimentional debugger 1 and adjust
Whole knob；The two-dimentional debugger 1 of cylinder fixes fixed block 2 by multiple adjustment knobs, and the center of fixed block 2 sets that there are one circles
Hole, the side above circular hole set that there are one lean on block；The circular hole and measured piece major axis size are mating.
The test system of a kind of test device using the servo-actuated speculum resolution ratio, it is characterised in that filled including test
It sets, parallel light tube 4 and preset lens 5；Parallel light tube 4 and preset lens 5 are respectively placed in the two-dimentional debugger 1 of test device by block
The both sides of opposite face, and the optical axis coincidence of optical axis and the tested servo-actuated speculum 3 being placed on 1 circular hole of two-dimentional debugger.
Advantageous effect
A kind of servo-actuated speculum resolution test device proposed by the present invention and test system, including two-dimentional debugger and solid
Determine block.Two-dimentional debugger is placed on the objective table of optical bench, the adjusting knob by adjusting two-dimentional debugger to fix
Block keeps relative level, then fixes servo-actuated speculum to be measured with the present apparatus, parallel light tube and preset lens are respectively placed in survey
The two-dimentional debugger that trial assembly is set finely tunes the light that two-dimentional debugger so that parallel light tube is sent out, warp by the both sides of the opposite face of block
It crosses and enters preset lens after being reflected with index glass.The present apparatus so that servo-actuated speculum need not be adjusted in entire test process repeatedly
Position, you can the picture of parallel light tube is quickly found out in preset lens, to which the measurement of servo-actuated speculum resolution ratio be rapidly completed.This
Invention is not only applicable in the measurement of servo-actuated speculum, it may also be used for normal optical part and similar optical element measure, in optics
There is important application prospect in part testing field.
Present invention has the advantage that：The first, this method is simple and reliable, is easily achieved, and is measured except initial workpiece is servo-actuated speculum
When, needs to adjust outer, and follow-up measure is not required to adjust, and can substantially reduce the working time (average 5 minutes i.e. 1 measurable)；The second,
Using the device, speculum measurement process is entirely servo-actuated in addition to initial workpiece, can be completed by one man operation, working efficiency obviously carries
It is high；Third is not easy injuring part surface by the servo-actuated speculum of present apparatus test；4th, this method has a wide range of application, and not only fits
Measurement for being servo-actuated speculum, it may also be used for normal optical part and similar optical element measure；

Specific implementation mode
In conjunction with embodiment, attached drawing, the invention will be further described：
Operation principle：The image in different resolution generated by parallel light tube 4, after being servo-actuated the reflection of speculum, before entering
Set mirror 5, the measurement that observer completes to be servo-actuated speculum resolution ratio by the image in different resolution observed on preset lens 5.
The test device of servo-actuated speculum resolution ratio, two-dimentional debugger and fixed block composition, the circular hole of fixed block with it is tested
Part major axis size is mating, being disposed vertically by the sustainable measured piece of block above circular hole.The present apparatus is placed on two-dimentional tune when use
In test stand, debugger is placed on the objective table of optical bench, the adjusting knob by adjusting two-dimentional debugger makes fixed block
