Electron Beam Evaporation 101

For the non-physics aficionados, electron beam evaporators (e-beam for short) are powerful devices that allow scientists to evaporate very difficult materials such as oxides, metals and magnetic substances. The process itself is very similar to thermal evaporation but often produces higher quality results. These systems accomplish vaporization by targeting a material with a strong electron beam within a vacuum environment. Once vaporized, the material can then be used as a coating.

What are they used for?

The films produced by these machines can fit into two broad categories: optical/oxide films and metallic films. The first would include everyday products such as eyeglasses for the visually impaired and a variety of camera lenses, ranging from mobile phones to professional grade removable ones. Metallic films also have quite the range of products. These e-beam coatings are used on watches, tools, batteries and more.

Advantages and Disadvantages

Due their more simplistic nature in comparison to ion beam sputtering methods (IBS) and ion assisted deposition machines (ADM), evaporation systems for e-beam are the most popular for manufacturing thin films. They also have a lower associated cost of implementation. These alternate systems, in particular sputtering, also have a lower likelihood of heating, and thus damaging, the substrate on which the coating is being applied. Films applied using an e-beam process are high quality and extremely resistant to wear.

While this could vary depending on the desired use of the system, this form of evaporation does not have better step coverage in comparison to IBS and IAD methods. Potential for a non-uniform evaporation rate is also a cause for concern with these systems, although this typically only arises over long periods of time as a result of filament degradation. Overall, the popularity of these systems speaks for itself, they produce consistently high quality coatings with minimal side effects.

How do I choose a system?

Manufacturers and researchers alike eventually reach the question: what is the best e-beam evaporation system? While it can vary between what you’re using the product for, ultimately the best way is to go through a reputable seller and try to find other using the devices in a similar manner and inquire for a review.

Old To New With Digital Remastering

Investing in digital photo scanners is a big deal. This product can do a lot for you in both your professional and your personal life. A photo scanner can enable you to preserve all of the old memories you have sitting around in boxes and bags in your closets. They can also help you to scan important flyers and photos you might need for your work place. Whether you plan to use the scanner once in awhile or on a consistent basis, the investment can become a worthwhile one after only a few uses. When it comes to buying digital photo scanners, it was easy to do when you’re armed with the right tips and tricks.

There are so many different digital photo scanners to choose from on the market. Most of them have something different to draw the table. The specific model you choose to purchase should greatly depend on what you want to use the scanner for.

Professional use would require a more industrial option while personal use might need only a simple model. Make a listing of the reasons you’ll use the scanner and make sure the man you choose provides all of the functions you need in order to handle all of your needs. Think ahead so you buy a product that provides you with a little room to grow.

How Could You Know…

If you want to remaster old photos or you need to make sure that what you scan results in crisp and clear images, you ‘d like to be sure that the image quality off your new photo scanner is reliable. The bigger the resolution, the better quality your pictures will be. Paying close attention to the spectacles of the models you’ve got your eye on will allow you to determine which products will provide you with the quality you need.

There is no point to shop for digital photo scanners that aren’t compatible with your other digital items. Whether it is a computer, a digital camera, or old film that you wish to scan in order to generate new images that are vibrant and of high quality, you need to make sure that the potential photo scanner is compatible with your other digital products.

Then came the news that The Beatles stereo remasters (but not the mono mixes) would be made available digitally except not how everyone assumed they’d be made available. Instead their entire 1960s catalog was going to be contained in mp3 and FLAC on a USB flash drive. I was fairly shocked by this (as I think most Beatles fans were.) I do not think anyone really even considered the notion that they would release their music digitally on USB instead of as digital downloads.

This means checking the specs and even asking the sales person if you’re in doubt. Luckily most newer models come equipped to handle almost any type of digital equipment thrown at it so you should not have a problem finding something that will cater to your needs. The more you need your scanner to do, the more expensive it’ll be so bear this in mind when determining how you plan to use your scanner.
