Tungsten Alloy Radiation Focusing Ring - China

price: contact company for price

Focusing ring used to adjust the lens so that the subject appears sharp

on the film or CCD. Most cameras now have automatic focus ( AF) , some

have manual focus override ( MF) and some have a fixed focus ( F) lens

that ensures things from about 1.5 meters to infinity are relatively

sharp. A few cameras have a power focus ( PF) , which is a manual

method, using a motorizedtungsten alloy radiation focusing ring. Lenses

with a ring that allows a good grip make tungsten alloy radiation

focusing ring easier to adjust and focus manually. We can provide

tungsten alloy radiation focusing ring as your requirements and tungsten

alloy radiation focusing ring offered by us is qualified.

A low- cost lens doesn' t have a tungsten alloy radiation focusing ring. Found in very basic cameras. The lens is set to a distance of around three meters and relies on the depth of field to bring everything from about one and a half meters to infinity. The quality is always a compromise over a lens with adjustable focusing. Tungsten alloy radiation focusing ring is good to our health.

An optical device is built into older cameras or added as an attachment. That is used to work out the subject distance by comparing two viewpoints. You see a double image and adjust the lenses until the images form one which gives a distance reading that can then be transferred to the focusing ring.

Why Use Tungsten Alloy Radiation Shielding?

Compared to traditional radiation shielding materials such as lead and boron carbide, tungsten alloy radiation shieldings provide excellent density with small capacity. At the same weights tungsten alloy radiation shielding with high density alloy can provide the same energy absorption as lead using 1/ 3 less material.

When the tungsten alloy radiation shielding weight is certain, more density, more denser, and the thickness would be thinner. Tungsten alloy radiation shielding material could be made with thinner thickness.
