Galileo is the first to be credited with designing the first compound microscope. The invention of the optical microscope, which is the one most used today, is traced to the Netherlands around 1590, where two eyeglass makers (Hans Lippershey and Zacharias Janssen) designed the basic version of what is used today. In the 1950s, advances in lighting technology for microscopes expanded their usefulness in many scientific disciplines. Lighted optical microscopes developed in two ways, as single lens and compound lens microscopes. For the most part, compound lens optical microscopes are the major type in use today.

Compound microscopes provide the highest resolution possible in an optical microscope, but they are sensitive devices and need to be taken care of to operate properly. Today, you will find lighted compound optical microscopes everywhere from classrooms to hospitals, professional labs, and even aboard the International Space Station. All modern lighted optical compound microscopes have the same basic set of parts that make up the device. Between manufacturers there may be slight differences, but for the most part, they are very similar. Before doing any work on or even with a modern lighted optical compound microscope, it is a good idea to become familiar with the individual parts that make up the device. The user’s manual for the microscope should contain a list of all parts and a diagram identifying the location of each. The base of a modern lighted optical compound microscope is heavily weighted to stabilize the device when in use. Most of the wiring is contained within the base;

a powerpack may be housed in the base of cordless rechargeable microscopes intended for field use. The base also holds the lighting source and will be the spot you will need to know in order to change the light source if it burns out. Depending on the design, the base may extend as a solid piece or may be the recess for the upper half of the device that contains the objective, objective turret, and eyepiece and is controlled by the focus wheel. Moving up from the base, the light source is mounted on the base just below the condenser lens and diaphragm. The light source is provided by either a halogen lamp, LED array, or lasers on more specialized models. For most people who will be changing their own light sources, it will be bulbs or arrays they will be changing out. The condenser lens takes the light produced by the light source and focuses it onto the sample for viewing. The diaphragm operates as a light filter so that the amount of light exposed can be adjusted as needed.

Using the two in combination helps focus the sample for observation. The frame is the mounting hardware for the condenser lens and the diaphragm. It attaches to the base and is also the mount for the focus adjustment knobs. The stage is mounted on top of the frame as well. The stage holds the specimen that will be viewed through the eyepiece. The stage is designed with a hole in the center so that the light is concentrated through the condenser lens and the diaphragm onto the 25 x 75 mm glass slide that holds the specimen. The focus wheel controls the vertical adjustment of the stage with both coarse and fine adjustment knobs. This enables the microscope to adjust the view of specimens of various thicknesses. A modern lighted optical compound microscope will be fitted with one or more objective lenses. These lenses focus on the portion of the sample that is centered on the hole in the stage and transfer the magnified image to the eyepiece. The objective can magnify images 5 to 100x actual size.

Higher end lighted optical compound microscopes can be fitted with higher magnification objectives and objectives designed for special purposes. The objective turret mounts below the eyepiece and holds multiple objectives, so that users can switch between objectives quickly and without having to remove and mount different objectives. The turret may rotate both clockwise and counter clockwise, depending on the design and the manufacturer. The eyepiece may be one or two eye apertures mounted above the objective turret that are used to view the specimen on the slide. Depending on the design of the eyepiece, it may be adjustable, allowing the user to customize the view to his or her eyes. This is especially important for persons who wear prescription glasses or contacts. Now that you are familiar with the modern lighted optical compound microscope, it is time to work and change the light bulb or LED array. Before beginning, make sure that changing the bulb or array yourself will not void any part of any existing warranty.

The first thing that you need to do is look in the microscope’s user manual and see what type and size light bulb or LED array will be needed for the replacement. Once that information is identified, check the manual for any specific instructions about changing the light bulb or LED array that the manufacturer provided. Some microscope manufacturers will use set screws with a flat head set screw to secure the light source cover to the base of the microscope. Other makers will use a set screw with a rough knob on the end so that removing the cover can be done without tools. Otherwise, a small thermostat or jeweler's screwdriver should do the trick. Before beginning, raise the microscope optics and frame as high as possible to get as much work space as possible. Loosen the set screw enough to allow the light source cover to lift free of the base. Some covers may have the added security of screwing on and off as well as being held by a set screw. If that is the case, screw the cover until loose and then remove it.

Set the cover to the side, ensuring not to get fingerprints on the inside glass lens and do not lose the set screw. Depending on how the modern lighted optical compound microscope is made, the bulb or LED array may either clip into place or screw into a threaded receptacle. Remove the bulb or array and set it aside in a place where it cannot be broken. Using a soft cloth, handkerchief, or wearing a cotton glove, remove the bulb or array from its package and install it. Take special care not to touch the bulb or array with your skin. Natural oils in the skin can be transferred to the bulb or array if touched. This can cause one or two issues in that when the bulb gets hot it will heat the oils, which can cause the bulb or array to blow, or the oils will burn and discolor the bulb or array, which will affect the image quality. Both results will require the bulb or array to be replaced. Using the same rules as with the bulb or array; the cover needs to be handled carefully so that no oils are transferred, and no dust, dirt, sand, or other debris is allowed to get on the inside of the cover’s lens.

Replace the cover as dictated by its design and tighten down the set screw. After the job is completed, wrap the old bulb in paper towels or old newspaper and tape it closed. This will protect the hands of anyone who handles the trash bag the bulb is disposed in. Whether looking for a modern lighted optical compound microscope, looking for replacement bulbs or arrays, or other accessories for the device, there are several options available on eBay. To locate modern lighted optical compound and other types of microscopes on eBay, open any eBay page and enter "microscope" into the search window and click search. When you do this, eBay will offer a few options in the search window to help narrow the results. The same thing goes for light sources and accessories; to find them, either enter "microscope light bulb" or "microscope accessories" into the search window and click search. When the results page opens, be sure to take advantage of the several filter options made available to shoppers.

Whether you are new to eBay or have been around awhile, everyone can benefit from taking a look at the eBay University Learning Center. Topics covered on the learning center page include information for those new to eBay, tips on how to buy, how to sell, along with additional information on how to increase sales. No matter what you need help with, there is a good chance you will find the answer on the learning center page. Modern lighted optical compound microscopes have improved vastly since they first started being available to the general public. Among the advances they have benefitted from, the lighting source going from reflective mirrors to electric light bulbs and LED arrays has done as much to make viewing specimens easier as any other advancement. In order to keep the microscope working properly, the light source needs to be working at top performance levels. From time to time, there is the need to replace bulbs and arrays to meet those performance levels. Before starting the project, take a few minutes to consult the user’s manual to identify the type and size of light source that will be needed, as well as guidance on how to change the light source.
