Embodiment

[0016] Example: Telescopes suitable for non-contact pyrometers such as figure 1 As shown, it includes an objective lens 1 and an eyepiece, an objective lens barrel 3 and an eyepiece barrel 4 connected to the objective lens 1 and the eyepiece respectively, and a reticle 5 arranged between the objective lens barrel 3 and the eyepiece barrel 4.

[0017] Wherein, the technical content added in the patent application for the present invention is: a relay lens barrel 6 is provided between the objective lens barrel 3 and the eyepiece barrel 4, and two The relay cemented lens 7 and the relay spacer 8 for separating and positioning the two relay cemented lenses 7 , the reticle 5 is arranged between the relay lens barrel 6 and the eyepiece barrel 4 . In order to facilitate alignment with a specific point, the reticle 5 is a cross (or dot) reticle. In order to plan installation and disassembly: the relay lens barrel 6 is threadedly connected with the objective lens barrel 3 and the ey...

Abstract

The invention relates to a telescope applicable to a non-contact type thermodetector. The telescope is characterized in that a relay lens cone is arranged between an objective lens cone and an eyepiece sleeve; an even number of relay balsaming lenses and relay isolating rings for isolating and positioning each relay balsaming lens are arranged between the relay lens cone and the objective lens cone; and a dividing plate is arranged between the relay lens cone and the objective lens cone. The telescope has the outstanding substantive characteristics that as the relay lens cone is additionally arranged between the dividing plate and the objective lens cone, and two relay balsaming lens and the relay isolating rings are additionally arranged inside the relay lens cone, the image resolution is improved and a tested object is reflected conveniently, truly and accurately through inverted images and erect images of the two relay balsaming lens; and in order to improve the applicability and expand the application range, to produce in scale conveniently, and to further reduce the production cost and improve the practicability, the lengths and the diameters of the relay lens cone, the objective lens cone and the eyepiece sleeve are provided.

Description

technical field [0001] The invention relates to a telescope suitable for a non-contact thermometer. Background technique [0002] The telescope used in the existing non-contact thermometer comprises an objective lens and an eyepiece, an objective lens barrel and an eyepiece barrel respectively connected to the objective lens and the eyepiece, a reticle arranged between the objective lens barrel and the eyepiece barrel . Since the non-contact thermometer has high requirements on the accuracy of the temperature measurement point, and the existing non-contact thermometer has poor imaging clarity and is difficult to accurately align with the measured object, which affects the temperature measurement effect. Contents of the invention [0003] The object of the present invention is to provide a kind of telescope that is applicable to non-contact temperature measuring instrument, set up relay lens barrel between reticle and objective lens barrel, and the even number relay ce...
