Embodiment approach 1
[0070] Next, an embodiment will be described below. figure 1 It is a diagram showing the configuration (optical system for measurement) inside the measurement probe 40 according to the first embodiment of the present invention. The measurement probe 40 serves as the above-mentioned Figure 19 (a) The color luminance meter shown, Figure 19 The measurement probe 4 of the colorimeter shown in (b) is used. As an example of the measurement method, with the above Figure 17 Similarly, the color luminance meter is configured to include a measuring probe 40 arranged to face the display screen 3 of the liquid crystal display 2 to measure light from the display screen 3 , and a measuring device main body 5 to obtain color luminance based on the output of the measuring probe 40 . . In addition, as another example of the measurement method, a colorimeter is configured to include a measurement light irradiation unit that irradiates measurement light to the object to be measured, a me...
Embodiment approach 2
[0094] Figure 13 It is a figure which shows the internal structure (optical system for a measurement) of the measuring probe 41 which concerns on 2nd Embodiment of this invention. The measurement probe 41 with the above figure 1 The shown measuring probe 40 is similar, and corresponding parts are denoted by the same reference numerals, and description thereof will be omitted. That is, this measuring probe 41 is equipped with: the objective lens optical system 11 that receives the light from the object to be measured; the single fiber C that is incident on the outgoing light emitted from the objective optical system 11; A branch optical system 12; a plurality of colorimetric optical systems 131, 141, 151 that are respectively arranged corresponding to each output end of the branch optical system 12 and detect each output light emitted from each output end. A biconvex lens 11a with positive optical magnification is used in the objective optical system 11, and a bundled optic...
Embodiment approach 3
[0098] Figure 14 It is a figure which shows the internal structure (optical system for a measurement) of the measuring probe 42 which concerns on the 3rd Embodiment of this invention. The measurement probe 42 with the above figure 1 The shown measuring probe 40 is similar, and corresponding parts are denoted by the same reference numerals, and description thereof will be omitted. ie, instead of figure 1 While the plurality of colorimetric optical systems 13 , 14 , and 15 in the measurement probe 40 of the first embodiment are shown, a plurality of colorimetric optical systems 132 , 142 , and 152 are used in the measurement probe 42 of the present embodiment. These colorimetric optical systems 132, 142, and 152 respectively include: single-line optical fibers 13C, 14C, and 15C to which incident light from the branch optical system 12, which is emitted from the other end side of the bundled optical fiber 12a in this embodiment; The optical lenses 13D, 14D, and 15D enter ou...
