Polarizing microscope
Polarizing microscope is a microscope used to study so-called transparent and opaque anisotropic materials, which has important applications in science and engineering such as geology. All substances with birefringence can be clearly distinguished under a polarizing microscope, of course, these substances can also be observed by staining, but some are not available, and polarizing microscopy must be used. Reflective polarizing microscope is a necessary instrument for the study and identification of birefringence substances using the polarization characteristics of light, which can be used by the majority of users to do single polarization observation, orthogonal polarized light observation, and cone light observation.
Light microscope
It usually consists of an optical part, an illumination part and a mechanical part. Undoubtedly, the optical part is the most critical, which consists of an eyepiece and an objective lens. As early as 1590, Dutch and Italian spectacle manufacturers had created microscope-like magnifying instruments. There are many types of optical microscopes, mainly bright field microscopes (ordinary light microscopes), dark field microscopes, fluorescence microscopes, phase contrast microscopes, laser scanning confocal microscopes, polarizing microscopes, differential interference difference microscopes, and inverted microscopes.
Electron Microscope
Electron microscopy has similar basic structural characteristics to optical microscopy, but it has much higher magnification and resolution ability than optical microscopy, which uses electron flow as a new light source to image objects. Since Ruska invented the first transmission electron microscope in 1938, in addition to the continuous improvement of the performance of transmission electron microscopy itself, many other types of electron microscopy have been developed. Such as scanning electron microscopy, analytical electron microscopy, ultra-high voltage electron microscopy, etc. Combined with various electron microscopy sample preparation techniques, it is possible to conduct in-depth research on the structure of the sample in various aspects or the relationship between structure and function. Microscopy is used to observe images of tiny objects. It is often used in biology, medicine and the observation of small particles. Electron microscopes can magnify objects up to 2 million times.
Desktop microscope, mainly refers to the traditional microscope, is pure optical magnification, its magnification is high, the imaging quality is better, but generally large volume, not easy to move, mostly used in the laboratory, inconvenient to go out or on-site testing.
Portable microscope
Portable microscopes are mainly an extension of the series of digital microscopes and video microscopes developed in recent years. Different from traditional optical magnification, handheld microscopes are digital magnification, which generally pursues portability, small and delicate, easy to carry; And some handheld microscopes have their own screen, can be independent imaging from the computer host, easy to operate, and can also integrate some digital functions, such as support for photography, video, or image comparison, measurement and other functions.
Digital liquid crystal microscope, first developed and produced by Boyu Company, the microscope retains the clarity of optical microscope, brings together the powerful expansion of digital microscope, intuitive display of video microscope and simple and convenient portable microscope and other advantages.
