American Optical (Spencer) Microscope Bulbs

We have a large selection of American Optical microscope bulbs, which help to clearly illuminate specimens under the microscope. The American Optical (AO) microscopes are often used in educational environments, and because they receive a lot of use, it’s important to have extra microscope bulbs on hand. We offer a variety of AO Spencer microscope light bulb replacements with various lighting color temperatures, shapes, and sizes.

These vintage American Optical microscopes are still in working condition, but they require lighting to illuminate the samples that are being observed. Depending on the number of hours used, American Optical Spencer microscope bulbs will need to be periodically replaced. Most of the AO Spencer microscopes require incandescent light bulbs, but others use halogen, fluorescent, and tungsten illumination. All of our AO Spencer microscope replacement bulbs have a long lifespan. You can find a selection of microscope bulb replacements for American Optical Spencer microscopes and many more microscope brands online from New York Microscope Company at affordable prices. Be sure to also browse our microscope parts and accessories.
