A light source should have a wide dynamic range, to provide high intensity illumination at high magnifications, and lower intensities so that the user can view comfortably at low magnifications. Better microscopes have a built-in illuminator, and the best microscopes have controls over light intensity and shape of the light beam. If your microscope requires an external light source, make sure that the light is aimed toward the middle of the condenser. Adjust illumination so that the field is bright without hurting the…

Many display cases offer all-around views with mirrors. Cases can have mirrors in the back, bottom, or top to help provide better views of your collectible. Some cases, however, do not include mirrors, so it is…
There are several different ways to deliver a presentation. You can use a slideshow using software such as Microsoft PowerPoint. This allows you to display text, videos, pictures/photos, music etc. Generally a slide will consist of very short bullet points or minimal information so the audience can keep in mind what is being discussed while the presenter gives more information. Presentations can be delivered verbally as a speech, though these tend not to keep the audience’s attention all of the time especially if it is a long speech. Using a projector is another way of delivering a project. It in essence uses a speech type presentation but allows things to be shown to the audience via the projector to keep interest and attention. This method is used a lot in classrooms and during lectures. Flip charts or white boards can also be used as a means of delivering a presentation particularly during interactive sessions where feedback is required from an audience such as while brainstorming or doing a consultation.…
Inverted, confocal, and polarized light microscopes are industrial microscopes. An inverted microscope locates the illumination system above the stage and the lens system below the stage. A confocal microscope or laser microscope uses a laser-to-light image one plane of a specimen at a time. Polarized light microscopes use two polarizers. These polarizers are perpendicular to each other so that only light which passes through the specimen reaches the eyepiece. Light is…

The shortest lens is the scanning objective; you use it to locate the object on the slide. The medium-length lens is the low-power objective. The longest lens is the high-power objective. Multiplying the power of the eyepiece lens and the nose piece lens gives you the total number of times an object will magnified.…

As the magnification increases, then the amount of the specimen you can see (the field of view) gets smaller.…
Thelight source is below the stage and the light shines up through the specimen and then through the lenses.…
The first models were originally used by the police for criminal profiles and in the United States Military for training and lectures. The body of the overhead projector is a large box containing a bright lamp and fan which functions to cool the device. On the top of the box is a clear lens platform that light passes through in order to reach the lenses above the box. Hovering over the fan and box is a long neck with one or two mirror lenses. These lenses catch the light coming from the bottom of the device and project it toward a board or blank canvas resembling a flat map. Many recent models provide a doughnut size plastic wheel for adjusting the lenses of the projector for the preference of the user. The overhead projector was a huge success in education. Notes and lectures could be prepared before the…
Barco entered the projection systems market in 1981 with the development of a video projector for showing motion pictures in airplanes. Its first projector, named the BarcoVision1 (BV1) was well-received and sold strongly in the U.S and European markets. After this success, Barco’s board of directors met to evaluate the company’s three potential directions: (1) It could downgrade its technology to suit consumer video applications (2) it could upgrade its technology for long-distance, high-performance video projection or (3) it could enter the untested market for computer applications. Seeing significant potential expansion in the projection market for computer applications, Barco made the decision to grow its projection division. In 1983, BPS introduced the BarcoData 1(BD1), the first computer compatible projector.…
The screen displays two sets of the same image, and the lenses direct the light from the images to your eyes - each eye sees only one image. Your brain puts the images together and you interpret it as a three-dimensional image. This kind of technology does present some issues such as: dramatically lowering resolution, cannot be turned off for standard 2D content, only works in one direction (usually landscape) and requires the user to stand in a sweet spot to view it. However, RED is confident these issues are fixed with its “holographic”…
