When it comes to lasers and collimation, one of the most trusted names in the business is guru Howie Glatter. His uncompromising quality and dedication to above average products, not only put his name above the rest – but in demand as the finest available on today’s market. Usually a manufacturer doesn’t take the time to explain to a customer exactly why their product excels over others – or why it performs better – but not Howie. Here’s what he has to say about his new Howie Glatter Laser Collimator:

It may sound strange, but the magnifier with the highest power isn't always the best choice. The human eye has an optimal viewing distance: the closer we hold an object to our eyes, the more of its detail we can theoretically see, but it will be out of focus. That's where the magnifying glass comes in. A magnifier with a 2X power, for example, enlarges an object and lets us see it as though it were two times closer to our eyes, but the object remains in focus. Does that mean that a magnifier offering 20X power is ten times more useful than our 2X magnifier? Not necessarily. There are limits to the practicality of a high-powered magnifying glass, because of the way that magnification, focal length and field of view work together.

Buying a brand name magnifier, while not always a guarantee of quality, means you can contact the manufacturer if anything goes wrong. E-Tay Industrial Co.,Ltd. specializes in magnifier manufacture more than 30 years with more than 5000 square meters of factory building area .

Always check the lens for scratches. 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 lasers in my collimators are class IIIa lasers (maximum beam power: 5 thousandths of a Watt), and are quite safe if used with reasonable precaution. Direct or mirror-reflected eye exposure to the laser beam should always be avoided! You must be careful when collimating to ensure that the beam does not enter anyone’s eye. There is no problem in viewing the beam’s impact directly on a surface as long as the surface produces a diffuse reflection. The beam impact may also be safely viewed on a mirror or lens surface if the reflected or transmitted beam is not directed towards your eye. Information from studies I have seen suggests that in order to induce permanent damage, a class IIIa laser beam must stay focused on the retina for a long time. It’s unlikely for this to happen because the pupil is a very small target and because we have a blink and aversion reflex to bright light. However, all precautions should still be followed to avoid the beam entering anyone’s eye! A badly miscollimated Newtonian or Cassegrain telescope may allow the beam to exit the front of the telescope, so when collimating, check first by pointing the telescope at a wall or screen to see if the beam is getting out. With unobstructed telescopes such as refractors, the beam will always exit the front of the telescope, so run a strip of masking tape across a diameter of the dew cap opening as a safety beam stop.

The focal length of a magnifier is the distance from its lens to the object being viewed, when the object is in focus. The power and focal length of a magnifying glass are actually inversely related. In other words, the higher the magnification, the shorter a magnifier’s working distance is, and vice versa. Having sufficient room to manoeuver beneath the lens is an important consideration when your hobby or project requires the use of tools, and it’s one of the reasons why a higher magnification isn’t always the better choice.

Do you need to enlarge the print of your book, map, newspaper, or crossword puzzle?- Consider a handheld reading magnifier .Do you want to look fashionable when taking your magnifier to the restaurant or grocery store for deciphering menus and labels?- A pendant or keychain magnifier might work best for you.Do you need to magnify a hobby that requires the use of your hands or other tools, such as knitting or model-building?- One of the many hands-free options is probably your best choice.Does your project involve studying the fine details of a gem, stamp, or document?- A jeweler's loupe is ideal for this type of work.

2X and 3X 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.

First and foremost, you should decide what purpose your magnifying glass is going to serve. It’s far better to let the project determine the magnifier required, than to try and turn a single magnifying glass into a one-size-fits-all tool:

When I started manufacturing laser collimators I realized that in order to produce consistent and accurate results they must be highly resistant to mechanical shock, so that internal laser alignment is maintained. I experimented with this aspect of collimator construction and developed a design which tremendously increased shock resistance. After aligning the laser within 15 arc seconds, I shock test each collimator by whacking it against a block of urethane plastic (urethane prevents marring), striking it at least a dozen times on three axis. I then recheck the laser alignment, and if it has not changed the collimator passes. I believe this is the most important difference setting my collimator apart from all others I know of. They will withstand a shock equivalent to dropping from eyepiece position, up the ladder on a big Dob, without alteration of laser alignment.

Although the perfect lightweight magnifier, combining a clear, high magnification with a wide viewing area is an optical impossibility, finding the perfect magnifying glass for your personal needs is not only possible, it's a definite reality.

Located in Taiwan since 1980, E-TAY INDUSTRIAL CO., LTD. is a magnifying glass products manufacturer. It's wide range of magnifying glasses include, magnifying glass with light, eclipse glasses, kids magnifying glasses, dome magnifiers, reading magnifiers, hand free magnifiers, hand held magnifiers, headband magnifiers, which are FDA approved and CE/RoHS compliant in the optical industry.

Inside the collimator is a solid-state laser diode, which emits an intense laser beam through a front aperture, exactly along the central axis of the cylindrical collimator body. The beam acts as a “reference line” from which alignments are made. For a laser collimator it is of supreme importance that the beam be aligned with the collimator’s cylindrical axis, for if it is not, the resultant “alignment” of the telescope optics will be off-center and asymmetric, and the telescope will produce aberrated images.

How to make a collimatedbeam

A number of components contribute to the performance of your magnifying glass, but for the average user, there are three main features you should consider:

LaserCollimator

I offer the red holographic collimators with a choice of either 650 nanometer or 635nm wavelength. The two lasers have the same radiometric power output, but because the human eye’s sensitivity to the shorter wavelength is greater, the 635nm. laser appears about two or three times brighter. The higher cost of 635nm laser diodes increases the collimator price, but it enables holographic collimation in brighter ambient light. If you intend to collimate in early twilight, it is a good choice. In darkness, however, the 650nm laser is quite adequate. Because single beam collimators concentrate all the laser light in the central beam, the 650nm laser is quite adequate for them.”

We recommand lighted 3X handheld magnifier for daily reading. 3X illuminated handheld magnifying glass provides evenly & sufficient lighting without glare and light viewing area for reading in dim condition.

The field of view refers to the size of the area that's in focus when viewed through a magnifier’s lens. In much the same way that focal length is inversely related to magnification, so too is the field of view. The higher the power of a magnifying glass, the smaller its field of view will be. That means you'll be able to see more detail with a higher magnification, but only across a relatively small area. Generally speaking, a 2-3X magnifier offering a larger field of view is better for scanning activities like reading, while the smaller field associated with a higher magnification would be more appropriate for the inspection of fine detail.

The beam from all red diode lasers used in collimators is fuzzy-edged and elliptical in cross-section. When collimating, you sometimes must judge the location of the center of the spot by eye. To improve collimating precision, all of my collimators (except 532nm) are supplied with a removable accessory plastic aperture stop having a 1mm hole, which push-fits into the laser aperture. It produces a tiny, circular beam impact which allows more accurate alignment. With the holographic collimators, it is not used at the same time as the holographic feature, and the diffractor must be removed to install the stop. With the stop inserted the beam impact at a distance of one meter or more looks like a star diffraction pattern, with a central dot surrounded by diffraction rings. The surrounding rings can help in centering the beam very accurately.

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.

A book magnifier comes in different shapes and styles. Determine first where you like to read. Perhaps it's your favorite reading chair, in your bed or at your desk. Where you like to read will make a difference as to what reading aids will be most helpful to you.
