Embodiment Construction

[0026] The following is further described in detail through specific implementation methods:

[0027] figure 2 It is the imaging system of the traditional desktop microhardness tester, that is, the finite distance imaging system. The finite distance imaging system adopts the finite distance imaging objective lens 2, and the output of the objective lens 2 is converging light, and the converging image plane must meet the standard parameters. That is, the distance a from the finite-distance objective lens 2 to the reflector 7 and the distance b from the reflector 7 to the eyepiece 5 in the figure must satisfy a+b=160mm in order to obtain a normal imaging effect.

[0028] figure 1 It is a new type of Vickers microhardness tester infinity imaging system, which includes amplifying imaging device, independent hardness indenter, converter device, reflection device, infinity auxiliary optical system imaging device, and observation tube device along the optical path from bottom to top...

Abstract

The invention relates to the field of hardness testers, and particularly discloses a Vickers microhardness tester infinite imaging system which sequentially comprises an amplification imaging device, an independent hardness pressure head, a converter device, a reflection device, an infinite auxiliary optical system imaging device, an observation tube device and an imaging eyepiece from bottom to top along a light path, wherein the amplification imaging device is used for amplifying an image of a to-be-tested sample, the converter device is used for conversion between the amplification imaging device and the independent hardness pressure head, the reflection device is used for changing the direction of a light path amplified by the amplification imaging device, and the infinite auxiliary optical system imaging device is used for reversing a parallel transmission light path into an imaging light path. The observation tube device is used for dividing a light path into two parts which are respectively imaged in the imaging eyepiece, so that the problems that the installation sizes of the objective lens and the eyepiece are difficult to correct during assembly and the imaging quality and effect of the system are influenced due to the fact that the mechanical tube length size of a limited imaging system of a traditional table type microhardness tester is fixed and cannot be changed are solved.

Description

technical field [0001] The invention relates to the field of hardness testers, and specifically discloses an infinity imaging system of a Vickers microhardness tester and a binocular microhardness tester. Background technique [0002] The Vickers hardness tester is a high-tech product of opto-mechanical integration. The machine is novel in shape, has good reliability, operability and intuitiveness. It is a new type of Vickers and Knoop hardness testing instrument using precision mechanical technology and photoelectric technology. . [0003] The imaging system of the traditional desktop microhardness tester is a finite optical system. Due to the standard design parameters of the microscopic system, the size from the imaging objective lens to the eyepiece is fixed and cannot be changed, otherwise the imaging quality will deteriorate or the imaging will not be possible. Therefore, a binocular observation module with a long optical path cannot be used. [0004] The finite dist...
