Magnification of a borescope is a measure of how large and object appears when viewed through the borescope as compared to its actual size when viewed from the same location without the borescope. Magnification of a borescope is not constant! The magnification changes as the object distance changes, with larger magnification when the object is nearer the tip of the borescope.

Our otoscope lens uses between a 3x- 4x magnification. We use the same magnification and focal length as the standard Welch Allyn? otoscope. We actually used their lens as our prototype when developing our otoscope. We figured they have been around for over 100 years and are the leading manufacturer of otoscopes in the world today and would be our best guide to what the optimum magnification and focal length should be.

Bigger is not always better when it comes to looking in the ear at the eardrum. The key to finding the proper magnification is to deliver enough magnification that you are able to get a clear picture of the eardrum as a whole yet at the same time magnify it enough to see the details that are important when doing your exam. If you over magnify you can see very clear details of a small area but you are unable to get a clear picture of the entire eardrum. See similar questions...

Answer: -- The magnification of any eyepiece used with your telescope will be the focal length of the telescope (consult your manual) divided by the focal length of the eyepiece. A telescope with a focal length of 1200mm will yield a magnification of 60x when you insert a 20mm eyepiece into the focuser. A telescope with a focal length of only 600 mm, however, will yield only 30x when used with the same 20mm eyepiece. See similar questions...

Answer: -- Use only enough magnification to provide a useable image. When you reach a point where the image has become so blurred as to lose useful detail, you are using too much magnification! At what point this happens depends on the object you are observing, the seeing conditions (atmospheric clarity and stability) and the size of your telescope (you can get more magnification out of a large telescope before images begin to blur).

Answer: -- A low magnification eyepiece has a wider field of view (the amount of sky you see when looking through the eyepiece) than a high magnification eyepieces. The low-magnification eyepiece therefore makes it easier to "capture" an object you are trying to find in your telescope. Your lowest magnification eyepiece will also give you the sharpest image as well as the brightest image . See similar questions...

Answer: -- Once you have located an object with your low magnification eyepiece, move the telescope so the object is as close to the center of the field of view as possible. Replace the low magnification eyepiece with one of higher magnification. If the object is not visible after you have changed to the high magnification eyepiece , go back to the low magnification eyepiece and start again. See similar questions...

Answer: -- A basic law of optics states that as magnification increases, image brightness decreases. In fact, if you increase magnification enough, an object will become too faint to see. This happens sooner in a small telescope than a large telescope . See similar questions...

MicroVu’s InSpec 2.X Metrology Vision Software reports the true magnification at the top of the video window. Through ‘Plug and Play’, the software knows what size of monitor you are using. If you change your monitor or if you change the resolution of your display, the magnification reported on your screen may change. You may see that at your lowest zoom level the magnification was reported at 18X, but when you install a larger monitor, you will be at 20X. See similar questions...

To find out what magnification you will get, divide your main objective's focal length (printed on the telescope tube or listed under specs) by the eyepiece focal length--in this case [the EIE], 10.5 mm. So, for a 700 mm focal length refractor such as a typical 60 mm department store telescope, this eyepiece will yield about 67 power (67x) [700 divided by 10.5 = 67]. See similar questions...

The percentage magnification tells you how many rows on the LCD monitor are used to represent each row of pixels in the image (the LCD monitor has discrete rows, but a more complicated column structure). At 100%, each row of the LCD monitor shows one row of the image; at 400% the image is enlarged by another factor of 4. The magnified image is rendered to the LCD with smoothing, so you don't see square blocks for the pixels, like you would on your computer using Photo Pro or Adobe Photoshop. See similar questions...

Please note as far as I know, I’m the first to actually refer to the magnification slider as (X/15) (X/18) where X is a number from 1 to 15 18… the amount that a map is zoomed in. So if you don’t know what I’m talking about when I say “Magnification Required” it’s probably because we made that term it up. See similar questions...

The speckFINDER’s magnification range is from 1X to 40X and beyond. “Beyond” means that the image can be magnified further, but due to digital magnification the image begins to pixelate. Most images will be acceptable at 50X, but depending upon the application, additional magnification may not be helpful. The zoom range is continuous with the press of a button with no need to change lenses. See similar questions...

Consider the distance you need to look through and the overall area you are observing or searching. For most surveillance or search applications, the higher the magnification or narrower the field of view, the more difficult it is to scan the area to avoid missing important objects or events. Usually a 1:1 lens with a 40° field of view provides optimal performance. For long-range observation or weapon sight applications, the magnification number will vary. See similar questions...

We use a common sense rule to stay away from synthetic concentrated substances, or drugs, in tablet form that could be toxic if multiplied. It is wise to eat foods that boost our immune system and our health and avoid sugar and flour foods as well as processed foods with additives. Here are some of the supplements we've been using: Green drinks, enzymes, vitamin C, minerals in electrolytic form (liquid) or other natural forms and acidophilus. See similar questions...
