Abstract
The utility model discloses a color photometer based on a uniform light tube uniform light source. The color photometer based on the uniform light tube uniform light source comprises a reference optical receiver, an optical receiver, a light source, a uniform light tube, a lens piece, a lens and an integrating sphere, wherein the optical receiver is arranged on one side of the light source. The uniform light tube is arranged on one side of the light source. The lens is arranged at a light emitting end of the uniform light tube. The lens is arranged on one side of the lens piece. The integrating sphere is arranged on one side of the lens. In measurement, a to-be-measured object is closely applied to the light emitting end of the integrating sphere. The optical receiver is arranged on a side of the optical receiver. The beneficial effects of the color photometer based on the uniform light tube uniform light source are that the structure is simple and reliable; the production technology is simple; optical losses of the light source due to uniform light tube are small; homogenizing is uniform; and the accuracy and stability of color measurement can be raised.
Description
Technical field
The utility model relates to a kind of colour photometer, particularly relates to the colour photometer of even light pipe homogenize light source.
Background technology
Have in the market the colour photometer of frosted glass homogenize light source, but frosted glass homogenize light source is larger to the loss ratio of light, general loss is greater than 60%, and homogenize effect is undesirable.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of colour photometer based on even light pipe homogenize light source.
The technical scheme solving the problems of the technologies described above is: based on the colour photometer of even light pipe homogenize light source, comprise reference light receiver, optical receiver, light source, even light pipe, eyeglass, lens, integrating sphere; It is characterized in that: described colour photometer is provided with optical receiver, light source one side arranges even light pipe.Even light pipe one side of described colour photometer arranges lens.Described colour photometer light source one side is provided with reference light receiver, and light source one side is provided with eyeglass.Even light pipe comprises light inlet and bright dipping end, and eyeglass is arranged on bright dipping end one side of even light pipe, and lens are arranged on a side of eyeglass, described scheme light source one side is provided with integrating sphere, integrating sphere has light inlet and bright dipping end, and measured object is positioned at the bright dipping end of integrating sphere, and optical receiver is arranged on integrating sphere side.Optical receiver is by forming containing the sensor of three kinds of color R, G, B.
The beneficial effects of the utility model are: simple and reliable for structure, production technology is simple, and even light pipe is little to the light loss of light source, and homogenize is even, can improve like this accuracy and the stability of color measuring.
Accompanying drawing explanation
Fig. 1 is the structural drawing of the colour photometer based on even light pipe homogenize light source.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As shown in Figure 1, colour photometer based on even light pipe homogenize light source comprises reference light receiver 1 and optical receiver 6, light source 2, even light pipe 3, eyeglass 4, lens 5, integrating sphere 7, described even light pipe 3 comprises light inlet 31 and bright dipping end 32, and described integrating sphere 7 comprises light inlet 71 and bright dipping end 72.Wherein, reference light receiver 1 is arranged on light source 2 one sides, even light pipe 3 is arranged on light source 2 one sides, eyeglass 4 is arranged on bright dipping end 32 1 sides of even light pipe, lens 5 are arranged on a side of eyeglass, integrating sphere 7 is arranged on a side of lens 5, and measured object is close to the bright dipping end 72 of integrating sphere when measuring, and optical receiver 6 is arranged on integrating sphere 7 sides.
As shown in Figure 1, the light that light source 2 sends injects the light inlet 31 of even light pipe, the source light of different angles even light pipe 3 interior after complicated multiple reflections in 32 outgoing of even light pipe bright dipping end.The conduct after eyeglass 4 reflections of emergent ray part light is received by optical receiver 1 with reference to light.And another part emergent ray is through eyeglass 4 transmissions, pass through again lens 5 focused transmission, light enters and connects bulb separation 7 from the light inlet 71 of integrating sphere, then penetrates from the bright dipping end 72 of integrating sphere, and the emergent ray of line focus impinges upon on the measured object of integrating sphere bright dipping end 72.Described emergent ray reflects to form reflected light through measured object, and described reflected light carries the colouring information of measured object.Described reflected light enters integrating sphere by integrating sphere bright dipping end 72, and after more than 7 diffuse reflection of integrating sphere, by optical receiver 6, is received.Optical receiver 6 is by forming containing the sensor of three kinds of color R, G, B.Reference light receiver 1 is change color and the optical power stability for monitoring light source 2.The all colours light signal of two optical receivers is sent into corresponding flush bonding processor and is carried out computing after oversampling circuit amplification, A/D conversion, thereby obtains the color parameter of tested article.
The beneficial effects of the utility model are: simple and reliable for structure, production technology is simple, and even light pipe is little to the light loss of light source, and homogenize is even, can improve like this accuracy and the stability of color measuring.
