Description
Technical field: the utility model relates to the portable infrared measurement of temperature optical devices of a kind of optical devices of infrared thermometer, particularly a kind of big distance coefficient.
Background technology: the distance coefficient of existing portable infrared thermometer is not more than 200: 1 both at home and abroad, so-called distance coefficient is meant the infrared measurement of temperature instrument, in product temperature measurement error scope, instrument (is shown in Figure 1 L: D) with measured object to the ratio of the inscribed circle diameter of surveying instrument direction projection apart from the maximum distance of testee.Distance coefficient is the major parameter of instrument, and the distance coefficient of instrument is big inadequately, and instrument just can't be realized the temperature survey of remote little target object.Realize that the remote temperature measurement particularly needs when the electric system contact temperature.
Summary of the invention: the purpose of this utility model is the portable infrared measurement of temperature optical devices of a kind of big distance coefficient of design, to realize that remote little target object is carried out temperature survey.
The purpose of this utility model is such realization, the portable infrared measurement of temperature optical devices of big distance coefficient, and it adopts reflective principle, it is characterized in that: comprise the germanium window, the primary mirror that are positioned at primary optical axis, germanium window, primary mirror are one in front and one in back; Catoptron A, the catoptron C of primary optical axis coexist between germanium window, primary mirror, the catoptron B, the rifle that are positioned at the primary optical axis upside are taken aim at, and light path is introduced into and enters rifle behind the catoptron B and take aim at, and wherein catoptron C is a prism, the prism inclined-plane becomes 45 degree light hurdle sheet and detectors, be positioned at the inclined-plane under.
Above-mentioned primary mirror is a non-spherical reflector, and the primary mirror focal length is at 130 ± 10 millimeters.
0.15 ± 0.02 millimeter of the center bore of the preceding light hurdle of described detector sheet.
The infrared energy of target emanation is by germanium window during work, through imaging behind primary mirror and the catoptron C on detector infrared light sensitive area; Accurate for the infrared light imaging, can take aim at the visual light imaging system that forms the unit and carry out accurate optics and manually locate by taking aim to see through catoptron A, catoptron B, rifle by the visible optical window of germanium window.
When detector sensitive area centrally aligned target, the picture of target visible light also finally is imaged on the graduation center that rifle is taken aim at after catoptron A catoptron B penetrates.
The utility model is because primary mirror is a non-spherical reflector, and the primary mirror focal length is at 130 ± 10 millimeters.The center bore 0.15+0.02 millimeter of light hurdle sheet before the detector.Can make distance coefficient reach 500: 1, be far longer than existing portable infrared thermometer, can measure far little target.
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:
Description of drawings: Fig. 1 is a schematic diagram of describing distance coefficient;
Fig. 2 is the utility model example structure synoptic diagram.
Among the figure: 1, primary optical axis; 2, germanium window; 3, primary mirror; 4, catoptron A; 5, catoptron C; 6, catoptron B; 7, rifle is taken aim at; 8, light hurdle sheet; 9, detector; 10, germanium window; 11, the center bore of light hurdle sheet; 12, testee; 13, measuring body; 14, the inscribed circle of projection.
Embodiment: as shown in Figure 1, it is L from the maximum distance and the testee (12) of testee (12) to inscribed circle (14) diameter ratio of measuring body (13) direction projection that Fig. 1 has provided measuring body (13): D.L: D is big more, and measuring distance is far away more, and distance coefficient is the major parameter of instrument, and distance coefficient is big, and instrument is accurately measured the temperature of remote little target object.
As shown in Figure 2, germanium window (10), primary mirror (3) one in front and one in back coexist on the primary optical axis (1), and germanium window (2) receives infrared light, and primary mirror (3) is an imaging lens, and catoptron A (4), catoptron C (5) are arranged between germanium window (2), primary mirror (3); Have catoptron B (6), rifle at primary optical axis 1 upside are taken aim at (7), and infrared light has two light paths, and one is the visible light path that is used to aim at usefulness, and another is measuring infrared light path.What enter behind catoptron A4, catoptron B6 that rifle takes aim at (7) by visible germanium window (10) is the aiming light path, is held by operator support.Another is to enter detector (9) by catoptron C (5) inclined-plane behind light hurdle sheet (8) by germanium window (2) again after primary mirror (3) reflection.The signal of detector (9) is being shown by processing of circuit.
Catoptron C (5) is a prism, and light hurdle sheet (8) and detector (9) are arranged under the prism inclined-plane.Primary mirror (3) is a non-spherical reflector, and the primary mirror focal length is at 130 ± 10 millimeters.The center bore (11) of the light hurdle sheet that detector (9) is preceding is at 0.154 ± 0.02 millimeter.
