Title:
HOLDER FOR TEMPERATURE ADJUSTMENT OF INFRARED SENSOR
Document Type and Number:
Japanese Patent JP2022134360
Kind Code:
A
Abstract:
To provide a holder for temperature adjustment of an infrared sensor, that is capable of highly accurately and stably controlling the environmental temperature of an infrared sensor using temperature adjusting air.SOLUTION: Provided is a holder 10 which accommodates an infrared sensor 1 in order to adjust a temperature of the infrared sensor 1, in controlling an environmental temperature of the infrared sensor 1 using temperature adjusting air 200. The infrared sensor 1 comprises: a lens 2 for receiving infrared rays radiated from a temperature measuring object 100; and a lens-barrel 3 for supporting the lens 2. The holder is provided with a wall part 12 which forms a ventilation surface 13 of the temperature adjusting air 200 at a position above the lens-barrel 3, and has an opening that is larger than an outer shape of the lens-barrel 3 at the ventilation surface 13, and further, forms a space S leading the temperature adjusting air 200 to the periphery of the lens-barrel 3.SELECTED DRAWING: Figure 1
