Embodiment Construction

[0021] The best embodiment of the present invention is to adopt the parabolic condenser to focus and collimate the infrared light emitted by the infrared light source, and to realize the reflection and convergence of the infrared light by using a spherical reflector and a conical light collector. The surface of the spherical reflector is gold-plated to ensure The infrared detector receives sufficient light intensity. The waterproof, dustproof and breathable film can not only effectively avoid the impact of dust, moisture and other impurities on the optical components, but also ensure that the gas enters the air chamber smoothly to obtain a faster response speed.

[0022] The structure of this embodiment is as figure 1 As shown, it consists of an infrared light source 1, a condenser lens 2, a temperature detector 3, a conical light collector 4, a measuring filter 5, a reference filter 6, a dual-channel infrared detector 7, a mirror 8, and a mirror seat 9. A bracket 10, a filte...
