What is the difference between optics and optical instruments?

An optical instrument is a type 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 component category in the instrumentation industry, and 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 experiments, national defense construction and social life.

In particular, the function of modern optical instruments has become an extension and expansion of the function of human brain nerves.

After a long period of development, optical instruments have formed several subcategories, such as illuminance meter, melting point meter, eyepiece, objective lens, ultraviolet radiometer, theodolite, level, colorimeter, spectrometer, photometer, other optical instruments, tool presetting instrument, spectrometer, vertical collimator, night vision instrument, imager, projector, refractometer, magnifying glass, microscope, telescope, prism, lens, filter, color filter, laser level, laser rangefinder and so on.

Category: Imager: Imager, also known as image measuring instrument, image-type precision surveyor.

It is a qualitative leap on the basis of measuring projectors, which improves the industrial measurement method from the traditional optical projection alignment to the computer screen measurement based on the digital image era. The image measuring instrument is based on computer screen measurement technology and powerful spatial geometry calculation software. There are two types of image measuring instruments: digital image measuring instrument (also known as CNC image measuring instrument) and hand-cranked image measuring instrument.

Introduction of three coordinates: three coordinates is generally known as coordinate measuring machine (CMM), which refers to an instrument that can express the measurement ability of geometry, length and circumference indexing within the spatial range of a hexahedron, also known as a coordinate measuring machine or coordinate measuring bed.

Tool microscope: Tool microscope, also known as the tool manufacturing mirror, is a high-precision two-dimensional coordinate measuring instrument used in tool manufacturing. It uses the optical principle to project the workpiece image to the eyepiece through the objective lens, that is, the workpiece is magnified into a virtual image by light, and then the loading table and eyepiece reticle are used as the measurement of size, angle and shape, and can be used as the surface of the workpiece to inspect the non-metallic luster.

Optical image projection: Optical image projector is a high-tech product that perfectly combines touch screen and image measurement technology, compared with traditional projection instruments, all the human-computer interaction windows of the instrument are basically realized on the touch screen. The whole function button is rich in humanized design, which makes the whole machine easy to operate and practical in function.

Compared with projectors and image measuring instruments, the operation is greatly simplified, and at the same time, in complex measurement operations, each step provides concise help**, guiding users to measure, and each step of the measurement is prompted in the information prompt bar, making the instrument operation very easy.

Optical parts, also known as optical components. The basic building blocks of an optical system. Most of the optical parts play the role of back image, such as lenses, prisms, reflectors, etc.

In addition, there are some parts that play a special role in the optical system (such as spectroscopy, image transmission, filtering, etc.), such as reticles, filters, gratings for optical fibers, etc. Holographic lenses, gradient refractive index lenses, binary optical elements, etc., are new optical components that have emerged in the past two decades.

Optical components, any instrument, device, and thing used to form an optical path, form optics, or be related to optics, such as lenses, optical fibers, plane mirrors, gratings, optical isolators, beam splitters, gratings, etc.!

Almost all individual components can be called optical components.

1. Optical components: called optical parts, the basic components of the optical system. Most of the optical parts play the role of imaging, such as lenses, prisms, and mirrors.

2. Optical components: parts that play a special role in the optical system, such as reticles, slow light sheets, gratings to find fiber parts with fiber punching, etc. Vertical bridge lenses, gradient refractive index lenses, and binary optical elements are new types of optical components that have emerged in the past decade or two.

Any instrument, device, or thing that is used to form an optical path, compose optics, or be related to optical withering is an optical element. For example:

1. Sheltered concave lens: It has a divergent effect on light, the incident light passes through the focal point, and the refracted light is parallel to the main axis after refraction through the concave lens.

2. Convex lens: It has a converging effect on light, and the incident rays are not syndactyly through the focal point, and the refracted rays are parallel to the main axis after being refracted by the convex lens.

In addition to this, there are lenses, optical fibers, plane mirrors, gratings, optical isolators, beam splitters, etc.
