Abstract

PURPOSE:To suppress the heating of an optical filter and to prevent thermal deterioration by providing the optical filter which rotates crossing an optical path with high light energy density in the optical path and cutting off unnecessary components. CONSTITUTION:When a xenon lamp with high brightness is used as a light source 7 for optical composition, light energy contains light components harmful to optical composition reaction such as ultraviolet rays and infrared rays and those should be cut off, but a fixed filter is unusable because of thermal deterioration. For this purpose, the discoid optical fiber 10 is arranged rotatably between a convergent lens system 8 and a photoconductor cable 5. Then, the filter 10 shifts in position successively to suppress the heating of the filter, preventing the thermal deterioration. Further, when the filter 10 is rotated at high speed, cooling effect is obtained by wind generated by the rotation to prolong the life of the filter.

This is a schematic overall configuration diagram showing an example (see Japanese Patent Application No. 56-11153), in which 1 is a housing that houses an artificial light source, and 2 is a person]
A cylindrical body of a lens system for converging light from two light sources, 3 a housing in which the focal point of the lens system is located, 4 a light conductor cable connector, 5 a light conductor cable, 6 a housing 3
This is a window provided in a part of the side wall of the lens system, through which the vicinity of the focal point of the lens system can be visually observed. Thus, the artificial light source device described in -I- focuses the light from the person-1 light source inside the housing 1 into the housing 2 through the lens system, and places the light-receiving end surface of the light guide cable 5 at the focal position. For accurate positioning, an artificial light source 7, a lens system 8 for focusing the light from the light source 7, and a light receiving cable for transmitting the light focused by the lens system 8; A fixing member that fixes the end side is integrally configured to determine the focal position of the lens system, and is aligned with the focal position so that the light receiving end surface of the light guide cable is perpendicular to the optical axis of the lens system. The guide cable is configured to be adjustable within a plane, so that the light-receiving end face of the guide cable can be accurately positioned at the focal position.

If a high brightness xenon lamp or the like is used as 7, the light energy emitted from the light source 7 will contain light components harmful to photosynthesis reactions such as ultraviolet rays and infrared rays, so these harmful light components should be cut. There is a need.

When the optical filter IO is rotated, the position where the optical filter 10 is used (that is, the position where high energy density light passes through the optical filter) changes sequentially, and the optical filter 10 is rotated.

理ん′できよう。The optical filter 10 is heated only at the area where the light energy hits, but the area where the optical energy hits changes as the optical filter 10 rotates. Since it is cooled when no light energy is applied to it, the optical filter 10 as a whole does not reach a high temperature. Moreover, optical filter 1
When the optical filter 10 is rotated at high speed, heat is removed by the wind generated as the optical filter 10 rotates, so that the temperature rise of the optical filter 10 can be suppressed more effectively. It is also possible to move the rotation axis 11 of the optical filter 10 in the direction of arrow A, that is, in the direction orthogonal to the rotation axis 11.
The range of use of the optical filter 10 can be further expanded, and the life of the optical filter 10 can therefore be further extended. In the following explanation, an example is shown in which an optical filter is provided in the optical path of light focused from an artificial light source, but the present invention is not limited to the above two embodiments, and the light energy density It can be easily understood that this can be applied to all optical paths with a high
