Problems solved by technology

[0002] At present, there are many kinds of microscope objective lenses with complete functions, but their structures are all optical glass lenses glued with resin or mechanically fixed in the objective lens barrel, which are only suitable for working environments at room temperature, low temperature or below 100°C
If the temperature of the working environment is too high, there will be chromatic aberration, aberration, image shift and other problems, which will affect the observation; it will even melt the adhesive resin and damage the objective lens
In recent years, although there are high-temperature metallographic microscopes that can withstand 1500°C, they are expensive and have narrow application fields

Embodiment Construction

[0015] Such as figure 1 As shown, a high-temperature microscope objective lens according to the present invention includes a microscope objective lens 1, a spacer 2 and an additional cooling device 3, and an external thread 11 is provided on the lower outer edge of the microscope objective lens 1. The inner edge of the additional cooling device 3 is provided with an internal thread 31 that matches the external thread 11 on the outer edge of the microscope objective lens 1 below, and the surface of the additional cooling device 3 is provided with a cooling hole 32, and the additional cooling device 3 The metal fixing ring 33 that is provided with below is used for fixing the spacer 2 between the objective lens and the slide glass. The metal fixing ring 33 is made of aluminum, copper, steel and gold with good heat conduction and high temperature resistance. The translucent sheet spacer 2 satisfies the light transmittance coefficient required by the optics, and the material of t...

Abstract

The invention relates to a high-temperature microscope objective lens, which comprises a microscope objective lens, a spacer and an additional cooling device, and an outer thread is arranged on the lower outer edge of the microscope objective lens. Described additional cooling device comprises the internal screw thread that its inner edge is provided with and the external screw thread of microscope objective lens bottom to match, the cooling hole that the surface of described additional cooling device is provided with, the bottom of described additional cooling device is provided with Metal retaining ring. The invention solves the shortcoming that the traditional objective lens cannot work in a high temperature state, and at the same time broadens the application field of the high temperature objective lens. The product has simple structure, convenient assembly and relatively low price.

Description

technical field [0001] The present invention relates to a new type of microscope, specifically an observation instrument capable of working under high temperature conditions (0-500°C). Background technique [0002] At present, there are many kinds of microscope objective lenses with complete functions, but their structures are all optical glass lenses glued with resin or mechanically fixed in the objective lens barrel, which are only suitable for working environments at room temperature, low temperature or below 100°C. If the temperature of the working environment is too high, problems such as chromatic aberration, aberration, and image shift will appear, which will affect the observation; it will even melt the adhesive resin and damage the objective lens. In recent years, although there are high-temperature metallographic microscopes that can withstand 1500°C, they are expensive and have narrow application fields. Contents of the invention [0003] The purpose of the pre...
