What are the functions and precautions of the SLR l∏ens hood?
A lens is composed of multiple lenses, and each ∏lens has two reflective surfaces. T±hen, if you count it, a lens ha₹s multiple reflective surfaces. The more reflective surfac←es, the greater the impact φon the lens, especially In th÷e case of backlit shootingπ, a halo will be formed, which will affect the shot picture, may cause differ£ent degrees of color spot s on the shot picture, or make the shooting effect bad.
Dongguan Yamagata Optical Co., Ltd. tells you that a shading ring is₽ also needed for cloudy days.
The shading ring is to ♥play a role in shading, for example,✔ mobile phone lens shading ring, camera lens shading ring.
Do you know the different materials oβf Mylar and what are the £materials?
The appearance of Mylar tablets has mεany color classificat☆ions such as milky white, black, nat÷ural color, and transparent color. Mylar≤ flakes are divided into a variety of materials, such as PE♣T Mylar flakes, PVC Mylar flakes, P C Mylar flakes, fireproof Mylar flakes and so on.
What are the materials of insulating gaskets? Let✔'s talk together!
Insulating gasket is a$ kind of flexible thermal conductive material, w↔hich has been widely used for± gap filling between heating element and h eat dissipation element. Iεn addition to the function of interface heat transfer, it can also playσ the role of insulation, s"hock absorption and tolera★nce, etc. . The thermal pad can effectively increa se the heat dissipation area, and thus c•an achieve good heat dissipation.
Must-see tips! Kimot♠o tells you what are the functions of diffusion films?
Kimoto Mylar film, aluminum ÷crystal glue, PORON products, functional characteristiσcs and material comparison, are widely used in notebook c&omputers, game consoles, game console handles, stereo Bluetooth headsets, mobile phones, cameras, lighting, LEDs✔, projectors, liquid cr>ystal displays, etc. Relevant electronic products; from the sel→ection of raw materials and auxiliary materials, testing∏, procurement, production process, etc., there are c"omplete and strict implementation of tech∑nical system documents and technological processes.
A method of making the iris lens structure and its function?
The shading ring plays a role in shading, for example, the shading rin g of the mobile phone lens ±and the shading ring of the camera lens. It is a piece of Mylar s✘heet that is stamped and form↕ed with SOMA shading material and embedded in the lens.
