What is an optical instrument

 

Optical instruments are composed of single or multiple optical devices. Optical instruments are mainly divided into two categories. One is optical instruments for real images, such as slide projector, camera, etc; The other is optical instruments that form virtual images, such as telescopes, microscopes, magnifiers, etc.

 

Optical instrument is a kind of instrument that can generate light waves and display images, or receive light waves and analyze and determine their optical properties. Optical instrument is a very important category in the instrument industry. It is an indispensable tool for observation, testing, analysis, control, recording and transmission in various fields of industrial and agricultural production, resource exploration, space exploration, scientific experiment, national defense construction and social life. In particular, the function of modern optical instruments has become the extension and expansion of the neural function of human brain.

 

Development of optical instruments

 

Optical instrument is a very important category in the instrument industry. It is an indispensable tool for observation, testing, analysis, control, recording and transmission in various fields of industrial and agricultural production, resource exploration, space exploration, scientific experiment, national defense construction and social life. In particular, the function of modern optical instruments has become the extension and expansion of the neural function of human brain.

 

With the increasing demand of downstream application fields, the market scale of domestic optical instrument manufacturing industry has also shown a rapid expansion trend in recent years. By the end of 2010, there were 395 Enterprises above Designated Size in China's optical instrument manufacturing industry. In 2010, China produced 30.0853 million optical instruments, a year-on-year increase of 25.45%, an increase of 35.99 percentage points over the same period of last year; During the year, the sales revenue of the whole industry was 53.167 billion yuan, a year-on-year increase of 19.26%.

 

In China's optical instrument market, the entry and success of multinational enterprises has become an indisputable fact. International famous manufacturers have entered the Chinese market one after another. Although some domestic enterprises gradually rise and occupy a leading position in the optical instrument manufacturing market, most enterprises have poor R & D ability. Compared with their foreign counterparts, high-end products are still at a disadvantage in technology.

 

military

 

Military optical instruments mainly refer to ordinary optical instruments in the visible band. They are the earliest in military application, and their technology is relatively mature. They have the functions of expanding and extending human vision, discovering targets that are invisible or invisible to human eyes, measuring the position of targets and aiming at targets. Generally, it can be divided into observation instruments and photogrammetric instruments. The former takes the human eye as the optical information receiver, and the latter records the scene information with photosensitive film. Ordinary optical instruments are mainly composed of optical system (objective lens, image conversion lens, dividing lens, eyepiece, etc.), lens barrel and precision mechanical parts. The optical system of the observation and measurement instrument is mainly the telescope system, which can enlarge the viewing angle and make people see the distant scenery, which is convenient for measurement and aiming. The optical system of photographic instruments is mainly photographic objective lens. In order to meet different requirements, a variety of lenses such as large aperture, long focal length and zoom have been developed. Military visible light instruments mainly include telescope, artillery mirror, steering wheel, periscope, sight, rangefinder, optical theodolite, camera, interpretation instrument, etc. Although optoelectronic instruments with advanced technologies such as infrared, low light level and laser have appeared since the 1950s, ordinary optical instruments are still an important part of the supporting equipment of weapon system with the advantages of clear image, convenient use and low cost.

 

Classification of optical instruments

 

Imager

 

Imager is also known as image measuring instrument and image precision mapping instrument. It is a qualitative leap based on the measurement projector. It improves the industrial measurement method from the traditional optical projection alignment to the computer screen measurement based on the digital image era. Image measuring instrument is based on computer screen measurement technology and powerful spatial geometric operation software. There are two kinds of image measuring instruments: fractional image measuring instrument (also known as CNC imaging instrument) and manual image measuring instrument.

 

Introduction of three coordinates

 

Three coordinate measuring machine (CMM) is generally referred to as coordinate measuring machine. It refers to an instrument that can express the measurement ability of geometry, length and circumferential division within the spatial range of a hexahedron. It is also called three coordinate measuring instrument or three coordinate measuring bed.

 

Tool microscope

 

Tool microscope, also known as display mirror for tool manufacturing, is a high-precision secondary coordinate measuring instrument used in tool manufacturing. It uses the optical principle to image the workpiece and project it to the eyepiece through the objective lens, that is, amplify the workpiece into a virtual image by light, and then use the loading platform and eyepiece reticle to measure the size, angle and shape, which can be used as the workpiece surface for testing non-metallic luster.

 

Optical image projection

 

Optical image projector is a high-tech product with the perfect combination of touch screen and image measurement technology. Compared with traditional projection instruments, all human-computer interaction windows of the instrument are basically realized on the touch screen. The whole function button is full of humanized design, which makes the whole machine simple to operate and practical. Compared with the projector and image measuring instrument, it greatly simplifies the operation. At the same time, in the complex measurement operation, concise help pictures are provided at each step to guide the user to measure. Each step of measurement is prompted in the information prompt column, which makes the operation of the instrument very easy.
