stereoscopic microscope is the most frequently used and versatile microscope found in a crime lab. Its wide field of view and great depth of focus make it ideal for locating trace evidence that may be found at the crime scene. Furthermore its potentially large working distance makes it quite applicable for the microscope examination of big bulky objects.

The largest microscope in the world is the Large High-NA Optical Research Microscope (LHOM) located in the Institute of Photonic Sciences in Barcelona, Spain. It is an advanced optical microscope that allows researchers to visualize objects at the nanoscale level with high resolution.
A microscope may not be useful when observing specimens that are too large to fit within its field of view, such as entire organisms or large structures. Additionally, if the specimen is too opaque or thick, it may not allow light to pass through, rendering it invisible under a light microscope. Lastly, some materials, like certain metals, may require specialized imaging techniques that a standard microscope cannot provide.
The coarse focusing knob of a microscope should not be used with the high dry lens because it can lead to a rapid and large movement of the stage, potentially causing the objective lens to collide with the slide. This can damage both the lens and the slide, resulting in costly repairs or replacements. Instead, the fine focusing knob should be employed for precise adjustments at higher magnifications.
There are two Magellanic clouds. Large Magellanic Cloud and Small Magellanic Cloud. Distance to Large Magellanic Cloud: 158,200 light years. Distance to Small Magellanic Cloud: 199,000 light years.

In photography, the working distance is the distance between the camera and the subject being photographed. The focal length of a lens determines how much of the scene will be in focus and how large the subject will appear in the frame. Generally, as the focal length of a lens increases, the working distance also increases, meaning the photographer needs to be farther away from the subject to capture it in focus.
A telescope must gather large amounts of light from a dim, distant object; therefore, it needs a largeobjective lens to gather as much light as possible and bring it to a bright focus. Because the objective lens is large, it brings the image of the object to a focus at some distance away
microscope usually!
The large knob on a microscope is typically known as the coarse focus knob. It is used to quickly adjust the distance between the objective lens and the slide, allowing for rapid focusing on the specimen. This knob provides a significant range of movement, making it easier to locate the sample before using the fine focus knob for precise adjustments.
A magnifying glass, or to REALLY enlarge things, a microscope.
A dissection microscope is called a stereoscopic microscope. It has low magnification that is useful for viewing large, thick objects.

long distance? far distance?
I would check out Microscope World, they have pretty reasonable pricing. Try looking at Microscope Mall Online, they have a large selection and free shipping on some orders.
