Detailed Description
The following describes the embodiments of the present utility model in further detail with reference to the accompanying drawings.
The utility model relates to a light filter testing device, which comprises a light source 4, an optical measuring instrument 1 and a base 3, wherein an optical measuring instrument bracket 2, a chuck 5 and a light filter bottom plate 6 arranged between the optical measuring instrument bracket and the chuck are arranged on the base, the light source 4 is fixed on the chuck 5, the optical measuring instrument 1 is fixed on the optical measuring instrument bracket 2, and a light filter clamp for fixing a light filter is arranged on the light filter bottom plate.
As shown in fig. 1, screw holes with matched positions are formed in the optical measuring instrument bracket 2, the chuck 5, the optical filter bottom plate 6 and the base 3, the optical measuring instrument bracket, the chuck and the optical filter bottom plate can be fixed on the base through bolts, and when in measurement, the optical filter to be measured is mounted on the optical filter clamp, so that light energy emitted by the light source passes through the optical filter 10 and irradiates the optical measuring instrument 1.
In the specific embodiment shown in fig. 1 and 2, the chuck 5 is provided with a through hole, the light source is a parallel light source, and the chuck comprises a light source panel and a sleeve provided with a lens group, and the sleeve is fixed in the through hole. The lens group is generally a convex lens or a convex lens group, so that light emitted by the light source panel is converted into parallel light after passing through the lens group and irradiates on the optical filter. The through hole can be composed of a semicircular groove and a semicircular cover plate rotationally connected with the semicircular groove, the semicircular cover plate is opened, the sleeve is placed in the semicircular groove, and the movable end of the semicircular cover plate is connected with the semicircular groove through a pin or a bolt, so that the light source is fixed.
In the embodiment shown in fig. 2, the filter holder includes a filter bracket 7 fixed to a filter base plate, and a first mask housing 8 and a second mask housing 9, both of which are hexahedral without a bottom surface and one side surface, and the filter bracket includes a pair of parallel upright brackets. The interval of the parallel vertical support is matched with the interval of the bottom surfaces of the two light shield shells, the optical filter to be measured is installed in a space formed by surrounding the two light shield shells, then the hexahedral assembly without the bottom, which is formed by the two light shield shells, is sleeved on the parallel vertical support, and the two light shield shells can be fixedly connected through bolts.
In the specific embodiment shown in fig. 1 and 2, a vertical plate is arranged on one side of the optical measuring instrument support, which is close to the chuck, a screw hole is formed in the vertical plate, a transverse jacking bolt 11 is arranged in the screw hole, the optical measuring instrument 1 is fixed on the optical measuring instrument support 2 through a bolt at the bottom, and the optical measuring instrument is fixed in the horizontal direction through rotating the transverse jacking bolt. In order to make the whole device more compact, a through hole is arranged below the optical filter bottom plate 6, and a transverse jacking bolt can pass through the through hole, so that the distance between the optical measuring instrument and the optical filter is reduced.
