Wherein, said one group of attenuator is at least two.
Wherein, speculum guarantees light intensity decreasing, and CCD is not overflowed, simultaneously again can be proportional with overall light intensity, can reflect overall picture.
Wherein, filter, color difference eliminating.
Wherein, attenuator is when weakening light intensity and can assurance itself be unlikely to be damaged by high light.
Wherein, optically focused spare is contracted to whole hot spot can on CCD, can show size.
Wherein, CCD can capture hot spot fully under existence conditions.
Because all corresponding picture of the every bit of wick, this is superimposed after look like to be exaggerated, and our energy distribution curve through the back image of superposeing and the position of wick be corresponding one by one adjusts assembling.
Its method for using may further comprise the steps:
(1) light at first through speculum, has weakened most of light intensity, and the control speculum makes through the light intensity behind the speculum and is no more than 4% of gross energy;
(2) this part reverberation that passes through then is through filter, color difference eliminating;
(3) continue across two attenuators through the light beam behind the filter, weaken light intensity;
The light intensity of (4) passing then behind the attenuator is passed optically focused spare, and being contracted to whole hot spot optically focused can complete demonstration on CCD;
(5) at last through the energy distribution curve of CCD clear display light spot figure on screen, regulate adjustment focal length button, two curves are reached unanimity.
Wherein, the wavelength of the said light of step 1 is any monochromatic light of 400-800.
Wherein, the said optically focused spare of step 4 is the F50 Fresnel lens.
Wherein, the spot diameter 50-100mm that obtains of the said optically focused spare optically focused of step 4.
Beneficial effect: a kind of electrode alignment device and method for using thereof disclosed by the invention with parabolic reflector discharge lamp, simple in structure, can increase substantially the lamp holder assembly precision.
