Background technology
When stage lamp is made, not only need the design lamps shell, main is light source part.Light source and lens must be in a horizontal line, form a primary optical axis, and therefore the light fixture of especially a plurality of lens will need accurately know the focal length of each lens by the combination of lenses of a plurality of different focal.
Usually, measure lens focus when making light fixture, original metering system is to measure by hand, generally be that the design engineer holds curvature table focal length measurement, three fulcrums on the curvature table are aimed at the lens sphere read numerical value on the dial plate, record data after, converse focal length.The subject matter that this kind metering system exists, the one, if gauger's hand has shake, will bring error to measurement data, the 2nd, this mode can only be surveyed spherical lens, can't measure non-spherical lens.Because the radius-of-curvature of lens has error, the optical glass material density difference of lens, so refractive index is inequality, especially the radius-of-curvature of major diameter lens and focal length are difficult to measure accurately.
Summary of the invention
The objective of the invention is to solve the measurement that the hand dipping focal length of lens exists easily produces error, is difficult to guarantee to measure problem accurately, a kind of device of measuring the focal length of lens with laser beam is provided, this device is refracted to laser pickoff with generating laser irradiation lens, the focal length of lens is detected, easy to operate, measure accurately, cost is low, simple and practical, satisfied design engineer's needs.
The present invention is achieved through the following technical solutions its above-mentioned purpose:
A kind of lens laser focus-measuring device comprises guide rail and the slide that is installed on the guide rail, and described slide comprises first slide, second slide and the 3rd slide, and a side of each slide is equipped with fixing button respectively, and it is also fastening that each slide can be slided on guide rail; Be equiped with L type support on described the 3rd slide, the generating laser assembly be housed, in this generating laser assembly laser instrument is housed in the upper end of L type support; Be equiped with lens carrier on described second slide, lens are housed above lens carrier; Be equiped with L type support on described first slide, the laser pickoff assembly be housed, in this laser pickoff assembly laser pickoff is housed in the upper end of L type support.
Can be equipped with in the described generating laser assembly 5 laser instruments and with 5 corresponding switches of laser instrument, and be provided with and connect lead and built-in power supply.
Lens laser focus-measuring device provided by the present invention, comprise the generating laser assembly of energy emission of lasering beam and the laser pickoff assembly of receiving beam, lens subassembly is installed in the middle of generating laser assembly and the laser pickoff assembly, and generating laser assembly, laser pickoff assembly and lens subassembly are installed in simultaneously on the guide rail and can slide.In the generating laser assembly a plurality of laser instruments can be housed, a plurality of laser instruments send directional light, through lens refractions, focus on 1 F2 of primary optical axis after the refraction, second focus of Here it is lens, and the focus of employed lens often refers to second focus on the stage lamp.Parallel mobile laser pickoff, the photodiode in laser pickoff arrives the focal position, and receiver promptly sends signal, and pilot lamp is bright.
The present invention can install 5 laser instruments and 5 and the corresponding switch of laser instrument on the generating laser assembly of emission of lasering beam.Laser instrument in the middle of only opening, promptly sending beam of laser is primary optical axis.If open four laser instruments except that primary optical axis, can send directional light; To laser pickoff, laser pickoff sends signal through lens focus, and pilot lamp is bright.If pilot lamp does not work, be lens front and back position discomfort, mobile lens will be realized above-mentioned effect gently, finishes one-shot measurement.
The invention has the beneficial effects as follows:
1. easy to operate simple, measure accurate and visual, cost is low.
2. the calculating in the design processes simplified reduces error, improves work efficiency.
3. sphere, non-spherical lens all can accurately be measured, and diameter is all applicable by φ 50mm～φ 320mm.
