PURPOSE:To execute a correct temperature measurement irrespective of the distance to a body whose temperature is to be detected, by forming a condensing mirror by curving a plate-like elastic base material having a reflecting surface of infrared rays. CONSTITUTION:An infrared-ray transmission plate 2 is attached to an opening part of the tip part of a pistol-shaped body case 1, and on its inside, a condensing device 4 for condensing infrared rays from a temperature detected body 3, which transmit through the infrared-ray transmission plate 2 and made incident is provided. In the rear of the condensing device 4, a measuring and controlling circuit 5 is provided, and to a position corresponding to the trigger part of piston of the body case 1, a measuring switch 6 for operating its measuring and controlling circuit 5, and a focus adjusting dial 7 are attached. Also, a battery 8 which is used as a power source, and an indicator 9 are provided on its lower part, and the upper reverse side, respectively. As for a condensing mirror 41 of the condensing device 4, that which has curved a plate material for reflecting infrared rays, and having elasticity is used. By changing the length of an arc of a part where its plate material is curved, the radius of curvature is varied, and the focal distance of the condensing device is varied. |
