Where Can I Buy A Microscope ^HOT^

We start with the premise that choosing a microscope should be an enjoyable process!That said, there are a number of variables that go into selecting a microscope system. The process can be a little daunting. Moreover, there is a bewildering range of quality - from cheap plastic microscopes to the most expensive German and Japanese brands.This article, therefore, provides sensible advice to assist budding microscopists to make a more educated decision.We recommend that you refer to the Glossary of Microscope Terms when reading this guide.Before we start, you should know that everything in this article refers to light microscopes; that is a microscope that includes a built-in light source. There are other types of microscopes, such as electron or ultraviolet, but they are significantly more expensive and typically, used in commercial or scientific applications.

  • Are you puzzled over: What lighting is best

  • How to compare optics

  • Which components you need

  • ABBE, Iris, and DIN? Huh?

  • It's time for that confusion to END! Our goal is to keep you from making an expensive mistake. You'll learn: The major components of a student microscope

  • Important concerns about construction

  • Types of objective lenses

  • Major types of illumination

  • Focus and gear ratio

  • Lesser known components

  • About buying used equipment

Our goal is to help you make an informed decision and spend your money wisely.

Start by looking at microscopes with sturdy, well-built frames. The best are made of metallic alloys that minimize vibration, minimizing fluctuation with temperature variations. If a scope you are considering is made of plastic, walk away! It will not provide the performance you expect let alone hold up over time.

DIN, or "Deutsche Industrie Norm", is found on student microscopes and more reasonably priced professional equipment. DIN was pretty much "the" standard until this new century in which Infinity optics became more accessible due to dropping prices.

  • Make sure your compound microscope follows one of these two standards. In doing so, you'll be assured that your optics are properly color corrected

  • your objective lenses can be readily replaced if damaged

Look for DIN or Infinity in the advertisement, or ASK! For most hobbyists, DIN is fine. Even most medical and veterinary clinics we sell to are buying DIN. You'll pay a premium for Infinity, but these days laboratories demand it. But PLEASE, avoid that third standard, which is no standard at all, something you'll find in the cheapest microscopes.

First, the lenses are constructed to be "color corrected". A single objective lens on a microscope can be built with six, eight, ten or more glass lenses. (That is what gives a "Compound Microscope" its name.) If the design and construction were not right, some colors could be out of the focal plane, and thus are unseen. (Focal plane refers to the area in focus, which is by definition a specific distance from the objective.)

We've taken a look at the objectives, now we'll talk about the lens closest to your eye, the eyepiece (also called the ocular). You should look for a microscope with a "wide field" eyepiece. On a wide field eyepiece, the lens opening is significantly larger than one that isn't wide field.

First of all, it is easier to position your eye to see into a wide field eyepiece. The reason is simple. Imagine trying to peer into a box through a pinhole. It would be pretty tough. Now think about trying to look in through a half-inch hole. The larger the hole is, the easier it is to see within. It is the same way with the microscope.

If your microscope features changeable eyepieces, change them quickly when doing so. The reason is that each time you change eyepiece(s), you can introduce dust into the microscope in the places that are hardest to clean. It takes less than a second if you prepare for it properly.

Please understand that microscope resolution (or the ability to see close but separate points as distinct) comes from the objective lenses, not the eyepieces. All an eyepiece can do is magnify the resolution that is already provided by the objective.

If you will be using your microscope day in and day out for hours at a time, you need binocular (two eyepieces). There is no question about it. Binocular viewing is much more comfortable because you don't have to train your brain to ignore the information from one eye. You'll notice that just about every professional microscope on the market is binocular. Those who use these scopes need the comfort associated with two eyepieces.

That having been said, if your primary intent for this microscope is for use by a child, you actually may find that a monocular (one eyepiece) microscope is more appropriate for them. Sometimes children can have a difficult time with the interpupillary adjustment. Just like a pair of binoculars, a binocular microscope is adjustable to allow for different size people. The eyepiece distance is adjusted until a single image is seen. Sometimes little ones have a tough time with this. If you must have binocular though, just have them move their eyes over one space and just use one eyepiece until they are a little older.

In household lighting in the past several years we have seen the bulbs progress from incandescent (think Edison), to fluorescent (think curlycue), to LED (think efficient!). The same progression has taken place in student microscopes.

Make sure your new microscope has LED lighting, or at very least fluorescent. As of this writing, there are some very cheaply made microscopes available with tungsten lighting, which should be avoided.

While LEDs have become more and more common on student microscopes, they are now standard on newer professional microscopes, like our 3000-LED and Revelation III. Recent technology advances have made these bulbs brighter and more reliable.

While LED has become king of microscope lighting, some student microscopes do still have fluorescent lighting. It is a fairly white light when compared to incandescent (below), and operates at much cooler temperatures. The bulbs, in most cases, are readily available desk lamp bulbs easily found at home improvement stores.

Avoid any new or used microscope with a tungsten/incandescent light. The bulbs are extremely hot, produce yellow light, and were never standardized, so replacements can be very difficult to find. As mentioned earlier, there are some very cheap scopes around with these bulbs, so be careful when shopping.

On student microscopes, at the top and bottom of their focus range, young users will at times have the tendency to want to continue cranking down (or up) on the focus once it has reached the end of its range. A microscope that is equipped with a "slip clutch" will allow the focus knob to slip (i.e. turn in place) and as such protects focus gears from damage. If not advertised, ASK if the student microscope you are considering has a slip clutch. 041b061a72
