What are the functions and precautions of the SLR lens hood?
A lens is composed of multiple lenses, and each l®ens has two reflective surfaces. Then, if you count it, a lens has mul→tiple reflective surfaces. The more reflective sur✔faces, the greater the impact on the lens, especially In the ✘case of backlit shooting, a halo will be formed, which will affect the shot p icture, may cause different degrees of color spots on th•e 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 of Mylar and what are the materials?
The appearance of Mylar tablets has many color classifications suc♥h as milky white, black, natural color, ★and transparent color. Mylar flakes are div∑ided into a variety of materials, such as PET Mylar♦ flakes, PVC Mylar flakes, PC Mylar flakes, fireproof Mylar flakes and ≥so on.
What are the materials of insulating gaskets? Let's talk to<gether!
Insulating gasket is a kind of flexible thermal conductive material, whiσch has been widely used for gap fil¥ling between heating eleme'nt and heat dissipation element. In adαdition to the function of interface heat transfer,α it can also play the role of insulatλion, shock absorption and to✘lerance, etc. . The thermal pad can effectivel₽y increase the heat dissipation area, and thus can a∑chieve good heat dissipation.
Must-see tips! Kimoto tells you what are the functions of diffusion filφms?
Kimoto Mylar film, aluminum crystal glue, PORON proεducts, functional characteristics and material co₹mparison, are widely used in notebook computers, game consoles→, game console handles, stereo Bluetoo th headsets, mobile phones, camer as, lighting, LEDs, projecto←rs, liquid crystal displays, etc. Relevant electronic produc♣ts; from the selection of raw materials and auxiliary materials, testing,♣ procurement, production process, etc., there are complete and stric't implementation of technical system documents and technolo'gical processes.
A method of making the iris lens structure and its functio→n?
The shading ring plays a role in shading, for ↑example, the shading ring of the mobile phone lens a×nd the shading ring of the camera lens. It is a piece of Mylar sheet that is sδtamped and formed with SOMA shading material and embedded in the l§ens.
