PURPOSE:To measure a feeble ultraviolet intensity at an arbitrary part in a view of an observing system by intensifying thoroughly an ultraviolet image and dividing said image to observing and measuring systems. CONSTITUTION:The ultraviolet image generated by a material 1 is formed on a photoelectric surface of an ultraviolet image intensifying device 3 by an objective lense 2, the amplified output image converted to visible rays is divided by a half mirror 9, and one is observed through ocular lense. The other light is formed an image on a photodetector 11 by a lense 10. The detector 11 receives the light of center part of the output image corresponding to the part shown by an index in view field, converts the light to an electrical signal, the signal is displayed on a display device 15 through an amplifier 12, an AD converter 13 and a sample holding circuit 14. |
