Title:
ULTRAVIOLET LIGHT SENSOR
Document Type and Number:
Japanese Patent JP2016081877
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an ultraviolet light sensor with improved sensibility without influencing on pseudo-discharge performance.SOLUTION: In a glass package 2 of an ultraviolet light sensor 1, a thickness of a top plate 22 facing an ultraviolet light source is made to be greater than or equal to 0.2 mm or less than or equal to 0.5 mm. Or, a ratio of the thickness of the top plate 22 and a diameter is made to be greater than or equal to 0.0157 and less than or equal to 0.0394. By making the thickness of the top plate 22 to be thin, ultraviolet light transmittance is heightened and the ultraviolet sensor is made to be highly sensitive.SELECTED DRAWING: Figure 1
