What does dark field mean?

Question 1: What does the dark field used in real estate mean? It is: case field. If you ask about typos, go directly to Baidu: Case scene!

Question 2: What is bright field? What is dark field? It refers to whether the wedding scene is fully lit or there is no other lighting except the stage and the couple's lights. The main problem is that the lights in the hotel itself cannot be turned on. The price is cheaper for bright scenes, because all kinds of lights are very expensive. The bright field mainly highlights the flower arrangement. The dark field is relatively expensive. Need surface lights, follow lights, computer moving head lights, par lights, floor lights. The two newcomers were the focus of the scene, and the rest was dark. The wedding effect will be better. And it’s more atmospheric. Don’t performances generally begin in darkness? Just for effect.

Question 3: What is a real estate dark field? Is it a crime scene?

It is the site where real estate is sold. It is called a case site because there are model rooms and models of this case!

Question 4: What is the meaning of polarized dark field in a metallographic microscope? Polarized light should be used, but dark field is rarely used! However, general metallographic microscopes will have polarizing devices!

Question 5: In real estate, what do people often mean by 'case'? It means the scene, also called the sales scene, which refers to the sales office scene.

For example, case sales, commonly known as "salesperson", is the salesman or saleswoman of a new commercial housing sales office.

Case security guards are generally security personnel recruited by property companies or real estate developers, who are specifically responsible for the security work of a community or a property jurisdiction.

Question 10: Why do high-end metallographic microscopes use brightfield and darkfield? The main characteristics of brightfield are based on the color and transmittance of the specimen. Specimens usually need to be dyed for easy observation. Of course, narrow the aperture or Upper and lower condensers are also available. Brightfield is the basis for all other optical microscopy. Dark field is a method designed based on the Tyndall effect principle to observe detection objects under dark background conditions. Under normal conditions, people cannot see indoor dust. This is because dust particles are exposed to strong direct light and diffraction. Interference But if we let the light pass through the window in dark indoor conditions, we can easily see it. This is because when the light is reflected or diffracted, the dust particles seem to increase in size. Dark field is a lens that uses a special method to prevent direct light from entering the objective lens. Instead, the direct light first passes through the dark field condenser and then changes its path so that it enters the object being measured obliquely. The surface reflects or diffracts the light into the objective lens to form a print on the object. Bright image on dark background
