At this time, Celestron has few spare parts (bulbs, objectives, eyepieces, etc.) for microscopes.

The most common types of microscopes are classified according to the type of view they provide. A high-power or compound microscope gives a highly magnified view of a tiny cell, mineral grain or pixel on a c]]> A microscope works by producing an enlarged image of a small object.

Because the eye can only focus to about 10 inches (25cm), this limits its ability to see fine detail by simply moving in close]]> The lowest-powered microscopes may not need any light other than that provided from room lighting or the sky. However, the microscope may be so close to the specimen that the instrument may shade it. Or you ]]> A condenser is a glass lens or lens system located within or below the stage (sub-stage) on compound microscopes. Its basic function is to gather the light coming in from the illuminator and to concentrate t]]> It’s very easy to figure out the magnification of your microscope. Simply multiply the magnification of the eyepiece by the magnification of the objective lens.

A microscope’s resolution is its ability to form separate images of lines or dots. It’s defined in terms of the actual distance between details on the object. The wave nature of light puts a prac]]> Microscope objective lenses will often have 4 numbers engraved on the barrel in a 2x2 array.

The distance from the top of the objective to the object being viewed is the parfocal distance. ]]> Filters are used to increase contrast and color correction for visual observations of specimens or slides. They may be used with live specimens as a non-lethal substitute for staining.

A wet objective means it operates with oil between the lens and the specimen. Oil concentrates light from the condenser and reduces light losses from reflection and refraction. Oil immersion is the technique]]> Most microscope objectives come in three basic designs: achromatic, semi-plan and plan.

An achromatic objective corrects for color and has a flat field across the central 65% of the image. It&rsqu]]> There are two working distances for microscopes: objective and stage. Together they define the space you have to work with objects and still focus with your microscope.
