Abstract
The invention relates to a high-temperature microscope objective lens, which comprises a microscope objective lens, a spacer and an additional heat radiating device. The outer edge of the lower part of microscope objective lens is provided with an outside thread. The additional heat radiating device comprises an internal thread which is arranged at the inner edge and matches with the outer thread at the outer edge of the lower part of the microscope objective lens. The surface of the additional heat radiating device is provided with heat radiating holes. A metal fixing ring is arranged below the additional heat radiating device. The high-temperature microscope objective lens settles a defect of incapability of operating in a high-temperature state in a traditional objective lens, and simultaneously widens an application field of the high-temperature objective lens. The high-temperature microscope objective lens has advantages of: simple product structure, convenient assembling and relatively low cost.
Description
Technical field
The present invention relates to a kind of Novel microscope, specifically one can the optical viewer of (0-500 DEG C) under the high temperature conditions.
Background technology
At present, micro objective of a great variety, multiple functional, but its structure is optical glass lens by resinoid bond or be mechanically anchored in lens barrel, is only applicable to the working environment of normal temperature, low temperature or less than 100 DEG C.Operating ambient temperature is too high, there will be aberration, aberration, resembles the problem such as to move and affect observation; Even can make binder resin melting and damage object lens.Though in recent years having can the high temperature metallographic microscope of resistance to 1500 DEG C, it is expensive, application is narrow.
Summary of the invention
The object of the invention is the defect overcoming prior art existence, provide a kind of micro objective that can work at high operating temperatures, structure is simple, handled easily, relative low price.
The technical scheme realizing the object of the invention is: a kind of heating microscope object lens, comprise micro objective, partition and heat abstractor, and described heat abstractor is arranged on micro objective lower end, and described partition is arranged between heat abstractor and micro objective.
Described heat abstractor is cyclic metal piece, below micro objective, outer rim is provided with external thread, the internal thread matched with the external thread of micro objective that described heat abstractor inwall is provided with, the louvre that described heat abstractor is provided with, the metal set collar that the below of described heat abstractor is provided with.
Described metal set collar material is aluminium, copper, steel, gold composition.
The material of partition is quartz, sapphire.
The operating temperature range of described heating microscope object lens is (0-500) DEG C.
The present invention has positive effect: 1, with traditional micro objective, these heating microscope object lens have employed the metal set collar in special heat-radiating hole, utilize metal set collar to possess heat conduction is good, heatproof is high characteristic, carry out the transmission of heat, under object lens environment at high temperature can be ensured, utilize louvre effectively to dispel the heat.
2, light transmission piece partition possesses the light-transmission coefficient meeting optical demands, heat insulation, high temperature resistant, the feature of good thermal shock stability.Make objective lens too highly can not occur aberration, aberration because of temperature, resemble and move.
3, structure is simple, cheap.
Accompanying drawing explanation
In order to make content of the present invention more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation, wherein
Fig. 1 is structural representation of the present invention.
Wherein: 1, object lens, 2, partition, 3, additive heat radiating device, 11, external thread, 31, internal thread, 32, louvre, 33, metal set collar.
Embodiment
As shown in Figure 1, a kind of heating microscope object lens of the present invention, it comprise micro objective 1, partition 2 and additive heat radiating device 3, below described micro objective 1, outer rim is provided with external thread 11.The inner edge of described additive heat radiating device 3 be provided with micro objective 1 below the internal thread 31 that matches of the external thread 11 of outer rim, the louvre 32 that the surface of described additive heat radiating device 3 is provided with, the metal set collar 33 that the below of described additive heat radiating device 3 is provided with, is used for partition 2 to be fixed between objective lens and microslide.Described metal set collar 33 material is aluminium, copper, steel, the gold composition that heat conduction is good, heatproof is high.Light transmission piece partition 2 meets the light-transmission coefficient of optical demands, and the material of light transmission piece partition 2 is heat insulation, high temperature resistant, the quartz of good thermal shock stability, sapphire.The operating temperature range of described heating microscope object lens is (0-500) DEG C.
Above-described specific embodiment; object of the present invention, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
