Description
Technical field
The utility model relates to the optical measurement field, relates to a kind of colorimeter optical system especially.
Background technology
In the color measuring field, colorimeter optical system is a kind of instrument commonly used.Current, most of color measurement instruments use tungsten lamp or xenon lamp as measurement light source.Yet, use the color measurement instrument of tungsten lamp to have shortcoming bulky, that be inconvenient to carry; There is the deficiency of power driving circuit complexity, poor stability in the color measuring apparatus of use xenon lamp.
The patent No. is CN201322648Y, the Chinese patent of " precise colorimeter integral ball formula optical system " by name, adopted led light source, and adopted the optical system with auxiliary optical path, but the auxiliary optical path light inlet causes the light in the integrating sphere to enter auxiliary optical path easily too near integrating sphere, sensor to auxiliary optical path causes interference, weakens auxiliary optical path to the stablizing effect of total system.
In addition, existing color difference meter not fast, simply, measurement and positioning mode accurately, user or by mechanical observation window visual fix, or use the electro-photographic head location of finding a view, and the use complex steps, the running time is long, poor accuracy, the staff slight jitter also can make the measuring position depart from and more inaccurate, and machinery or the electronic installation complexity of location, easily produces fault.
Therefore, need a kind of quick, simple to operate, accurate stable measurement color difference meter of data of measuring.
The utility model content
The technical matters that the utility model solves is to provide a kind of color difference meter system, the problem of loaded down with trivial details, the measurement data poor stability in location when solving colorimeter optical system and measuring the small size color.
For addressing the above problem, the utility model provides a kind of colorimeter optical system, comprise light source, light path, catoptron, integrator, measurement mouth, main induction device, auxiliary induction device, wherein, arrange one in the bottom of described integrator and measure mouth, described integrator connects described catoptron, light path is arranged between described light source and the catoptron, described integrator is provided with the main induction device, described auxiliary induction device is over against the direction setting of led light source, described measurement mouth is taper, is used for the location testee.
Above-mentioned colorimeter optical system, wherein, a described measurement mouthful employing taper positions.
Above-mentioned colorimeter optical system, wherein, the main induction device is arranged on the side of described integrator.
Adopt the technical solution of the utility model, used aiding sensors to constitute auxiliary optical path, structure is more simple, more is of value to measuring stability, has reduced the optical device in the light path, has reduced cost.Used and measured a mouthful location, improved the accuracy of measurement and positioning; Replace mechanically operated observation window and electro-photographic head, easy to operate, real-time location, fault are few; And the user is directly visual when measuring, judge fast and accurately and measure the mouth center that whether aims at the mark, simplified other with quasi-instrument to bit manipulation, shortened bit time, improved contraposition efficient.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present utility model, constitutes a part of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not constitute improper restriction of the present utility model.In the accompanying drawings:
