Description
One, technical field
The utility model provides a kind of light cup type infrared low-temperature measurement device, belongs to infrared rays survey device technique field.
Two, background technology
The optical system of existing infrared temperature measurement apparatus mainly contains two kinds of forms: transmission-type and reflective.Use the device of transmission-type very sensitive, but chromatic aberration correction is relatively more difficult to high temperature; To low-temperature measurement, the silicon and the germanium that are used for grinding eyeglass cost an arm and a leg, and be difficult for grinding, be difficult for the calibration debugging, so at this, major part is all selected for use reflective, and the photelectric receiver of common reflective devices and incident light are in reflective devices the same side, debug difficulty,, limited its range of application greatly so low-temperature measurement is the comparison difficulty for infrared rays survey.
Three, summary of the invention
The purpose of this utility model provides and a kind ofly can overcome above-mentioned defective, simple in structure, uses reflective principle, and realization can be surveyed the cup type infrared low-temperature measurement device of light of low temperature.
The purpose of this utility model is achieved like this: the cup type infrared low-temperature measurement device of a kind of light, comprise optical filter, infrared reflection film, the light cup, photelectric receiver, signal processing circuit, focal length adjustment device and housing, inboard at the light cup is coated with infrared reflection film, the big opening end of light cup is equipped with optical filter, the osculum end connects photelectric receiver, the photelectric receiver signal processing circuit places in the columniform shell, focal length adjustment device is focused by toroidal shell, described optical filter, infrared reflection film, the light cup, photelectric receiver, signal processing circuit, the focal length adjustment device unification is contained in the casing.The light cup that the cup type infrared low-temperature measurement device of light, its inside are coated with infrared reflection film converges at the infrared light of big opening end incident on the photelectric receiver of light cup osculum end, realizes photelectric receiver and the incident ray purpose in the both sides of light cup.

Five, embodiment
With reference to accompanying drawing, the cup type infrared low-temperature measurement device of the utility model light, it comprises optical filter (1) infrared reflection film (2), light cup (3), photelectric receiver (4), signal processing circuit (5), focal length adjustment device (6) and housing (7).Wherein the inboard of light cup (3) is coated with infrared reflection film (2), the big opening end of light cup (3) is equipped with optical filter (1), the osculum end connects photelectric receiver (4), photelectric receiver (4) signal processing circuit (5) places in the columniform shell, focal length adjustment device (6) is focused by toroidal shell, and described optical filter (1), infrared reflection film (2), light cup (3), photelectric receiver (4), signal processing circuit (5), focal length adjustment device (6) unification are contained in the casing (7).The cup type infrared low-temperature measurement device of light, the Infrared that measured target sends is by optical filter (1), inject the light cup (3) that posts infrared reflection film (2), Infrared is reflected and converges at photelectric receiver (4) and locate, and passes to signal processing circuit (5) by photelectric receiver (4) again.The light cup that its inside is coated with infrared reflection film converges at the infrared light of big opening end incident on the photelectric receiver of light cup osculum end, realizes photelectric receiver and the incident ray purpose in the both sides of light cup.Can receive all band infrared waves, help low-temperature measurement.
Claims (2)
1, the cup type infrared low-temperature measurement device of a kind of light, comprise optical filter (1), infrared reflection film (2), light cup (3), photelectric receiver (4), signal processing circuit (5), focal length adjustment device (6) and housing (7), it is characterized in that: the inboard of light cup (3) is coated with infrared reflection film (2), the big opening end of light cup (3) is equipped with optical filter (1), the osculum end connects photelectric receiver (4), photelectric receiver (4) signal processing circuit (5) places in the columniform shell, focal length adjustment device (6) is focused by toroidal shell, described optical filter (1), infrared reflection film (2), light cup (3), photelectric receiver (4), signal processing circuit (5), focal length adjustment device (6) is unified to be contained in the casing (7).
2, require the cup type infrared low-temperature measurement device of described light as right 1, it is characterized in that: the light cup (3) that inside is coated with infrared reflection film converges at the infrared light of light cup big opening end incident on the photelectric receiver of light cup osculum end.
