What Is Tungsten Alloy Radiation Focusing Ring?

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 motorized tungsten 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.

As we know, all microelectronic have radiation when we used. In order to resistant radiation from theses products, we have to protect measures to prevent it. Tungsten alloys is a best choices for tungsten alloy radiation focusing ring. Compared to traditional radiation shielding materials, tungsten alloy radiation focusing ring provide excellent value. A high-density alloy can provide the same energy absorption as lead using 1/3 less material. People are taking advantage of tungsten alloy reliable radiation focusing ring properties.

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 but high absorption of radiation in high density. That is why tungsten alloy radiation shielding material is suitable for raidation shielding. During design of shielding, tungsten alloy radiation shielding is calculated according to requirements of shield to abate the multiple shielding materials' thickness.

Formula: K = e0.693 d / 1/2

K: Shield weakened multiple

1/2: The tungsten alloy radiation shielding material of the half-value layer values

d: tungsten alloy radiation shielding thickness, with the half-value layer thickness of their units, you need to half-value layer thickness of the quality of translation into the thickness of the tungsten alloy radiation shielding, divided by the density of the tungsten alloy radiation shielding can be obtained.
