Most of the materials which are not suitable for flame cutting are pretreated with nitrogen. Based on the inert properties of nitrogen the resulting cutting surface will be oxide-free. However, slight contamination by oxygen or moisture causes discoloration on the cut surfaces. Nitrocut ensures the obtainment of high quality cut surfaces.

The X (times) factor of a magnifying glass refers to how much it magnifies. An average magnifying glass makes objects look 2 or 3 times bigger, which means it magnifies 2X or 3X. Geologists often like to have 5X to 10X magnification; however, anything higher than 10X is difficult to use in the field because the lenses are too small.

Laser technology is a versatile tool for numerous industries and applications. Whether in metal processing in automotive-, aircraft- or ship-building, in the semiconductor industry, in medicine or in food technology, lasers of various types are used everywhere.

Titanium, tantalum and magnesium are examples of materials that form nitrides, as they undergo strong reactions with nitrogen. In order to weld these materials without performing post-processing operations such as milling, grinding or pickling, the use of argon is recommended for cutting.

Cutting gases are selected according to the material to be processed. Materials which are suitable for flame cutting are treated with pure oxygen. As such, the purity of the gas has a strong impact on the cutting speed. Due to the high purity of Oxycut, the cutting speed can be increased by up to 20%, depending on the thickness of the sheet or plate.

I seek a magnifying glass to supplement my reading glasses but would like to try them out first. Where can I go to see and test before buying? My postal area is PE7 1QW.

Why is it that magnifying glasses aren’t labeled accurately and that the X doesn’t truly mean twice as big. If I view a quarter which is .75 inch and then view it from the same distance using a 10X lens I’d expect it to be 10 times the size 7.5 inches but it’s closer to 2 inches. What the hell ?

5X and 6X Lenses are the most popular choices for an average user as it offers higher magnification without sacrificing the field of vision (diameter of the lens). On the other hand, a 10X magnifier will reduce the field of vision significantly, but it will give you a closer look at tiny rocks, crystals, minerals, microfossils, etc.

I have not been able to personally view a selection of handheld glasses because what l need are too expensive for stores here to carry. I am therefore forced to go online. The problem there is to determine if what is offered meets my need. They all different prices from $5.00 to $1500.00. Apparently the greater the magnification the higher the price. So what do l order?

The most commonly used type of laser by far is the CO2 laser. In this type of technology, the laser beam is generated by using a three-component gas consisting of helium, nitrogen and the component that gives the system its name: CO2. The wavelength of the CO2 laser light is 10.6 μm and invisible to the human eye. Mirrors and lenses are utilized to direct and shape the laser beam.

When one thinks of a magnifying glass, they tend to think of the big Sherlock Holmes type lens. However, in actual use, you want a lightweight, and powerful magnifier that has impeccable optics and is simple to use. Utilizing the best magnifier for demanding jobs like inspecting diamonds and gemstones is essential to their occupation, while hobbyists who collect rocks and minerals just need to buy a decent magnifier that they can afford to lose.

Hold the lens up next to your eyes while bringing the object close to it - about a few centimeters from your face. The idea is to focus your attention through the magnifying lens, the same way you look through eyeglasses. If you normally wear glasses, you will need to keep them on. A magnifier won't correct for astigmatism as well.

Given the same X (times) factor, a larger lens is always better. There are tons of cheap inferior magnifying glasses out there claiming 20X, 30X, and even 45X magnifications, yet they sell for less than $10. These are false claims as any magnifier over 20X magnification will have such a small field of vision that they are no longer considered magnifiers, but rather loupes. Higher quality lenses with high magnifications are also more difficult to produce, consequently they tend to be more expensive.

Hi, notice on Amazon there are a plethora of magnifying glasses to choose from and very little information about quality of lenses as you point out above. But instead of beauty related products, I am interested in magnifying maps with tiny font or doing close electronics work in a hands-free mode. Do I want a headset or a floor mounted magnifying lens? The search is about! Chas

On Amazon 35mm & 50mm 3x glasses are available. Better to have 2 glasses of same size & put it in one case (cover) after opening original rivett , put two lens together having 2 or three small aluminum washers so glasses may not touch or rub each other & use a long rivett used in a baggage which at end has split part. I did that & works very nice for reading.

It is better to join two 35 or 50mm , 3 or 3.5x magnifying glasses with having thin one or two washers between glasses ro avoid rubbing & using a rivet which has a split at the end & qhich is normally used on baggages. This combination of glasses works fine for reading very small written letters.

I truly want to see the item at a minimum of five times its actual size, more probably 10 times the actual size because I would not be using a magnifying glass if I didn’t want to look at something really really small. I’m not using this as a reader. I bought a digital microscope but and somewhat unimpressed because I have to be a foot above the coin to be able to see the whole coin so I was hoping to be able to buy a hand magnifier with a 4 to 8 in lens that would give me nice easy clear views

The term “operating gases” refers to gases required to generate the laser beam. Depending on the equipment configuration, either the laser gas is produced from the three pure components in an internal mixer or a premixed product is used. The gases need to be extremely pure and free of disruptive contaminants in order to guarantee perfect operation of the laser. For the pure gases, Messer recommends the purities: CO2 4.5, N2 5.0 and He 4.6

I am trying to find a magnifying glass for a friend of mine that has muscular degeneration and is having a hard time reading the newspaper. She probably needs 5X strength. Where can she go to see one or buy one? The zip code is 44512, Youngstown Ohio.

Good Morning, I have been trying to find out how to enlarge the field of view on the 5 glass magnifying system but have not received an answer after sending two pictures of the product as requested.

2) Place the magnifying glass on a piece of white paper and see if the lens adds any color of its own. Then pick it up and examine other objects, specifically objects with more colors.

The view through the magnifying lens should be crystal clear with no internal reflections. Highlights should be sharp and brilliant, with no colored fringes. The lens should be achromatic. A flat object should not look buckled or warped. A magnifier should not be loosely put together.

Due to the better reproducibility, the use of premixed laser gases has become the preferred approach. With our Lasline products, Messer offers an extensive selection of Laser gases.  In general, the composition of the gas mixture depends on the type of laser. The manufacturer specifies the exact composition. A change in the composition can impair performance or damage the resonator. Messer offers a complete range of Lasline resonator gas mixtures, e.g.
