半径距離だけ塗布されない部分つまり基板１０が現われ
る部分が形成されている。FIG. 1 is a block diagram of a fluorescent pinhole plate. This fluorescent pinhole plate A has a substrate 10 coated with fluorescent paint 11, and this substrate 10 is supported by a frame 12. This fluorescent paint 11 emits visible light when irradiated with an ultraviolet beam. Further, a pinhole 13 having a diameter of 1 to 200 μm is formed in the center of the substrate 10 . A portion of the fluorescent paint 11 that is not coated by a predetermined radial distance from the edge of the pinhole 13, that is, a portion where the substrate 10 appears is formed.

て紫外線ビーム々（照射された位置が判別できる。With such a configuration, when the fluorescent paint 11 is irradiated with an ultraviolet beam, visible light fluorescence is generated in the irradiated portion. However, on the surface of the fluorescent pinhole plate A, the irradiated positions of the ultraviolet beams can be determined.
次にかかる螢光ピンホール板Ａを用いての点光源の作成

線ビームの光軸上には螢光板１５が配置されている。A condenser lens 3 and a fluorescent pinhole plate A are arranged on the optical axis of the ultraviolet beam 14. Furthermore, a fluorescent plate 15 is arranged on the optical axis of the ultraviolet beam that has passed through the pinhole 13 of the fluorescent pinhole plate A.

されている状態にある。With such a configuration, rough adjustment of the ultraviolet beam 14 is first performed. The ultraviolet beam 14 is focused by the condensing lens 3. At this time, if the fluorescent paint 11 is irradiated with the ultraviolet beam 14, visible light fluorescence is generated at this irradiation position. In this case, the irradiation position of the ultraviolet beam 14 on the fluorescent pinhole plate A is moved. This movement is performed such that the ultraviolet beam 14 is located on the exposed portion of the substrate 10. When the ultraviolet beam 14 is irradiated onto the substrate 10, no fluorescence is generated. Therefore, the ultraviolet beam 14 is in a state where the portion of the substrate 10 including the E-hole 13 is irradiated.
次に微調整が行われる。Fine adjustments are then made.

部分に可視光線の螢光が発生する。A fluorescent plate 15 is arranged. This fluorescent plate 15 is irradiated with the ultraviolet beam 14 that has passed through the pinhole 13, and visible light fluorescence is generated in the irradiated area.
この状態に紫外線ビーム１４はピンホール１３を含む基
板１０の部分での照射位置を微動させる。In this state, the ultraviolet beam 14 slightly moves the irradiation position of the portion of the substrate 10 that includes the pinhole 13.

螢光強度が最も高くなる。この結果、螢光ピンホール板
Ａにおいて紫外線ビーム１４の点光源が得られる。As a result, the focal point of the ultraviolet beam 14 is focused on the pinhole 1.
3, the fluorescence intensity of visible light on the fluorescent plate 15 becomes the highest. As a result, a point source of the ultraviolet beam 14 is obtained at the fluorescent pinhole plate A.

学系の調整が容易となる。In this way, in the above embodiment, the pinhole 13 is formed in the substrate 10 and the fluorescent paint 11 that emits visible light is applied around the pinhole 13, so that the irradiation position of the ultraviolet beam 14 can be determined. UV beam 14
can be easily passed through the pinhole 13 to obtain an ideal point light source. In this case, since a portion is formed around the pinhole 13 to which the fluorescent paint 11 is not applied, the ultraviolet beam 14 can be made to pass through the pinhole 13 through coarse adjustment and fine adjustment with certainty. Therefore, adjustment of the ultraviolet optical system becomes easy.

If you apply a paint that emits visible light not only by ultraviolet rays but also by light beams with wavelengths other than the visible light range, all wavelengths other than the caustic light range will pass through the pinhole 13 and become a point light source. Applicable to get.
