Abstract
The present invention relates to the improvement of a periscope. A lens body, a periscope barrel and a positioning accessory are all made of high temperature resistant ceramic materials. An objective lens set, a relay lens set, a compensating lens set and a light filter are all made of sapphire and silica glass. The front end is provided with an optical axis fine tuning sheet for adjusting the offset of a viewing field. The present invention has the characteristics of normal work assurance under the high temperature condition, good image quality, etc.
Description
The present invention relates to a kind of improvement of periscope.
At present; the periscope that under high-temperature condition, uses in the world; as the periscope of U.S. diamond company production and the periscope of China's production; the positioning supports parts are made by metal; optical imaging component is formed by the optical glass manufacturing; this periscope can only be lower than long-term work under 200 ℃ of conditions; for it can be worked, must increase the refrigeration protection of wind or water in addition, otherwise can burn out moment under hot conditions; but increased failure rate simultaneously again at the increase chilling unit; chilling unit can not be satisfactory, and then automatic drawing-out mechanism occurred, so that when refrigeration plant lost efficacy; can extract periscope out automatically; in order to avoid burnt out, even if like this, effect is also unsatisfactory; periscope often damages, and has to sometimes interrupt monitoring.
The object of the invention provides a kind ofly makes eyeglass by exotic material, the high temperature resisting periscope of lens body and annex.
The present invention is made up of lens body, objective lens, relay lens group, lens barrel, compensating glass group, light hurdle, optical filter, optical axis trim plate, positioning attachment, and lens body, lens barrel, positioning attachment are made by high temperature ceramic material; The high temperature resisting periscope front end is provided with the optical axis trim plate of adjusting visual field offset, and by white stone (Al
2O
3), quartz glass (SiO
2) make; Objective lens, relay lens group, compensating glass group, light hurdle, optical filter are by white stone (Al
2O
3) quartz glass (SiO
2) make.
The present invention has can guarantee operate as normal under excessive temperature (≤1500 ℃) condition, characteristics such as good image quality.
Accompanying drawing 1 is a section of structure of the present invention.
Below in conjunction with accompanying drawing the present invention is further described, location of the present invention and support component adopt high-temperature ceramic materials, optical imaging component adopts white stone and quartz glass, and compensating unit is installed to revise aberration, obtain good picture element, principle of work of the present invention is such, and lens body 1 and part lens barrel 2 with periscope during use insert in the observed high-temperature region (kiln), the other end is exposed and the camera system coupling, and positioning attachment 3 can make high temperature resisting periscope fine fixing.Scene is through objective lens 4 imagings in the high-temperature region, be delivered to compensating glass group 6 through relay lens group 5, after process light hurdle 7 and 8 pairs of picture qualities of optical filter are handled, deliver to camera system, can be in the pulpit observe situation in the high-temperature region, at work because during the temperature variation visual field offset by monitor, can adjust by optical axis trim plate 9, if in camera system, add zoom lens, not only can observe full visual field, also can observe the flame details.
