Description of drawings
To combine accompanying drawing and embodiment that the present invention is described further below, in the 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
It is as shown in Figure 1 that being used to of preferred embodiment of the present invention measured the frock clamp structure of optical filter transmittance; 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 is provided with installing plate 20, is connected on base 10 openings through screw is dismountable around the installing plate 20; And installing plate 20 is provided with first light hole 21, to appear light.On installing plate 20, also be provided with the compressing tablet 30 that is used for optical filter 40 is fixed on first light hole, 21 places; Compressing tablet 30 is provided with second light hole 31 of being convenient to optical filter 40 printing opacities, and the light that sends from light source 11 like this passes first light hole 21, optical filter 40 and second light hole, 31 backs and penetrates.On ground one illuminometer (not shown) can be set apart from 1 meter of light source, illumination that can 1 meter, measuring distance light source dead ahead, the same position light illumination when not adding optical filter 40 is compared then, and the ratio of gained is the transmitance of this optical filter 40.
After adopting the frock clamp of present embodiment, can guarantee same optical filter 40 position consistency that different number of times are measured, make measurement result more accurate so that optical filter 40 is fixing more steady.
In a further embodiment; As shown in Figure 1; Around first light hole 21 on the installing plate 20 with compressing tablet 30 on second light hole 31 on every side respectively correspondence be provided with fixed orifice 50, compressing tablet 30 is connected on the installing plate 20 through the device for clamping that passes fixed orifice 50 is dismountable.Like this when needs are installed optical filter 40; Can pull down device for clamping; For example screw is vacated the gap between installing plate 20 and compressing tablet 30, makes optical filter 40 to put in; And covering first light hole 21, the light that makes light source 11 send passes through the optical filter 40 and second light hole 31 from first light hole 21.After measuring completion, also can easily compressing tablet 30 be removed, to take off optical filter 40.
Preferably, first light hole 21 in the foregoing description and second light hole 31 all are arranged on the primary optical axis of light source 11.The light intensity that shoots out through first light hole 21, optical filter 40 and second light hole 31 like this is the strongest, and directivity is better, is convenient to select the position of measuring light illumination more, so that measure more accurate.
