My microscope has a filter wheel. How is it used?

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.Blue is...

My 100x objective is called a wet objective. What does this mean? What i...

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...

What is the difference among achromatic, semi-plan, and plan objectives?

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’s...
