Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the frock clamp structural representation of preferred embodiment of the present invention;
Fig. 2 is the frock clamp structural representation of another embodiment of the present invention.
Embodiment
Preferred embodiment of the present invention for the frock clamp structure of measuring light transmittance of optical filter as shown in Figure 1, it comprises the base 10 with recess, in the recess of base 10, be provided with light source 11, the opening part of base 10 arranges installing plate 20, installing plate 20 surroundings are connected on base 10 openings by screw is dismountable, and on installing plate 20, be provided with the first light hole 21, to appear light.On installing plate 20, be also provided with for optical filter 40 being fixed on to the compressing tablet 30 at the first light hole 21 places, on compressing tablet 30, be provided with the second light hole 31 of being convenient to optical filter 40 printing opacities, the light sending from light source 11 is like this through ejaculation the first light hole 21, optical filter 40 and the second light hole 31.On the ground apart from 1 meter of light source, one illuminometer (not shown) can be set, illumination that can 1 meter of, measuring distance light source dead ahead, then the same position light illumination when not adding optical filter 40 is compared, and the ratio of gained is the transmitance of this optical filter 40.
Adopt after the frock clamp of the present embodiment, can guarantee same optical filter 40 position consistency that different number of times are measured so that optical filter 40 is fixing more steady, make measurement result more accurate.
In a further embodiment, as shown in Figure 1, on installing plate 20 the first light hole 21 around and on compressing tablet 30 the second light hole 31 around respectively correspondence be provided with fixed orifice 50, compressing tablet 30 is by passing dismountable being connected on installing plate 20 of device for clamping of fixed orifice 50.Like this when needs are installed optical filter 40, can pull down device for clamping, screw for example, between installing plate 20 and compressing tablet 30, vacate gap, optical filter 40 can be put in, and cover the first light hole 21, the light that light source 11 sends is passed through optical filter 40 and the second light hole 31 from the first light hole 21.After measurement completes, also can easily compressing tablet 30 be removed, to take off optical filter 40.
Preferably, the first light hole 21 in above-described embodiment and the second light hole 31 are all arranged on the primary optical axis of light source 11.The light intensity shooting out through the first light hole 21, optical filter 40 and the second light hole 31 is like this strongest, and directivity is better, is more convenient to the position of State selective measurements illuminance, so that measure more accurate.
