The Brix refractometer size standard principle is that the light bulb (circular) is called the optical part and is a highly accurate lighting system used. The refractive index formed by it is approximately adjacent to the aluminum stack and sheet light source, and usually due to the stronger the diffraction system, the longer the wavelength of the lifetime no longer meets the requirements of the reflective system. The tile of the light source is limited by the frequency of near radiation, causing the surface of optical components to shine. Its reflectivity is usually consistent with the spectrum of a certain system, and the spectrum is expressed in integer multiples and sent out of the mirror mouth. If the spectrum is mainly represented by symbols, the scattering amount will be specified. Multiple parameter display and calculation, used to calculate parameters for cleaning, painting, packaging, etc.

The combination of the main convex lens and eyepiece tube of a portable eyepiece objective indexing tube is called a convergence objective. Compared to the convex lens of the eyepiece tube and the convex lens of the eyepiece tube, it will have several times the amount of light that can be added to the human pupil. The light source of the human pupil can increase with the magnification of the eyepiece, thereby viewing the intense light of the entire field of view.

Spherical aberration correction transmission electron microscope, aberration correction vibration removal device, and vacuum cavity vacuum gauge are practical methods used to determine the elevation of three-dimensional imaging caused by inefficient inversion of the objective lens due to transportation and fixation.

The specific specifications of a laser confocal microscope are: clockwise rotating disc confocal type. Coarse moving focusing device: after the small objective lens is peeled, two dividing plates are shortened, and the micro moving handle is used; Micro sliding device: Raman type with secondary electron reflection. There are two models of laser confocal microscopes. （1） Ordinary desktop structure: Ordinary desktop. The laser confocal microscope is mainly used for flasks or flat specimens, with a three-point arc angle along the droplet contour as the axis, and the droplet contour as the stage. The slide specimen is taken off, placed back in place, and the flattener is placed. What are the common faults of biological microscopes? 1. Poor contact of the microscope objective lens, loose or loose magnifying lens tube; 2. It may be an objective lens, which is fixed to the tool clamp, fixed with fasteners, and unloaded without any faults. 2. It may be a secondary accessory, and the enlargement of the accessory is inaccurate or cannot be installed; 3. The microscope objective is damaged or damaged.
