The eyepiece lens again magnifies the view as seen by objective lens. Tube Dia: 30mm Main tube. The magnification is how many times, the object has been enlarged. magnification at low, medium, and high power. Focal Plane: First Focal Plane Reticle. Since the objective lens has 10x printed on them at "low power". The total magnification would be 10 times 10. See below for the equation. The eye piece ( the part you look through, just to be sure) is ( almost always) 10x magnification. Say the objective lens magnifies 10 times (10x) and the eyepiece lens also magnifies 10x, the two together work as a team. Length: 9.4 inches. The tutorial initializes with the major optical train components (condenser, specimen, objective, tube lens, and eyepiece) of a virtual infinity-corrected microscope appearing in the window. Objective Lens: 24mm Diameter. Occasionally, when switching to the highest magnification lens you may need to make a slight adjustment to the fine focus, but this is not required when you start out with the 4x lens. Color: Comes in Black Color. This tutorial explores how changes in tube lens and objective focal length affect the magnification power of the objective in infinity-corrected microscopes. The total magnification (TM) for a microscope is determined by the power of the occular lens (10x) multiplied by the power of the objective lens being used. The objective lense ( the pieces that rotate, again just to be sure) are usually ( but not always 4x, 10x, and 40x. This lens has a magnification power that is measured the same way as the objective lens. Parallax Adjustment: Fixed at 100 yards distance. Thus the total mag. Reticle: Illuminated BTR reticle. Some optical instruments provide visual aid by magnifying small or distant subjects.. A magnifying glass, which uses a positive (convex) lens to make things look bigger by allowing the user to hold them closer to their eye. The magnification of the microscope is equal to the magnification of the ocular lens times the magnification of the objective lens. Examples of magnification. Magnification Power: Variable power of 1-4x. Most microscope objective lenses are parfocal, meaning once you have one objective lens in focus, all other objectives should be in focus as well as you move from 4x to 10x, etc. Weight: 18 ounces. The optical lens is 10 and the objective lens is 10; when the two are multiplyed together the total is 100x. Field of View (1x): 112 feet at 100 yards. This is called the eyepiece lens. To calculate the magnification, you will need to multiply the magnification of the ocular lens with the magnification of the objective lens. Explanation: i hope this helps C: Illumination Levels: 11 brightness intensity levels. The magnification power of low power (lp) is 100x.
