Microscope Parts & Accessories

Here are some of the more common parts and accessories for microscopes:

:: Microscope Eyepieces ::
Different eyepieces are useful for changing the magnification of a microscope. Eyepieces are specified by FN number, which indicates the field of view (FOV) when used with a 1X objective lens. For binocular and stereo microscopes, eyepieces should always be purchased as a matched set.

You can also get an eyepiece micrometer, also called a reticle. This consists of a tiny grid pattern etched on an eyepiece lens. It is used to make measurements of the size of objects seen through a microscope.

Barlow lenses are used to inexpensively double the magnification power of the microscope.

:: Microscope Lighting ::
Microscope lighting systems are available as external units to provide flexiblity in positioning and application use. Microscope illumination falls under three main types:

Free-standing halogen spot lighting

Self-supporting halogen, fiber-optic lighting (often with dual arms)

Fluorescent ring (annular) lighting that mounts around the nosepiece

:: Microscope Stands ::
Three major types of microscope stands are available and used for various applications:

Boom stands. Also called universal stands, boom stands offer the most flexibility and allow the microscope to be rotated into and out of position easily.

Post stands. Also called pole stands, post stands feature a focusing holder that can be moved up or down. Many pole stands have integral lighting systems.

Arm stands. Arm stands have integrated focusing holders and lighting. Articulated arm stands offer motion in three dimensions.
