_ is how big something gets

_ is the minimum separation distance to see 2 objects clearly;d

_ is how distinct the specimen is from the background

_ is put below the slide and objective lens to change how light is refracted; all light on specimen is passed to lens

this microsope is when light passes through the condensor, is focused on the specimen, then passes to the objective and ocular lens

this microscope has a condenser with metal plate blocking light directly on the speciman; light is reflected off the specimen

this is part of a microscope has a metal plate that blocks light directly on a specimen

this microscope retards and advances light waves to increase contrast of unstained bacteria

this part of a microscope advances light by passing it through a bullseye like condenser

this part of a microscope separates light into 2 perpendicularly polarized light

this microscope uses a wollasten prizm to separate light into polarized lens to detect 3d details of an organism

this microscope uses fluorescent light to view a specimen

this microscope uses confocal pinhole to view thick specimen

this is part of a microscope used in confocal scanning laser microscope to shut out light from all but one focal plane

this microscope is a light microscope that uses an electron beam instead of light beam; specimen must be extensively stained and fixed

this reflects electrons off a specimen to show 3-d cutside of a specimen

this microscope rotates around specimen using an electron source for images at various angles and are put together in 3d picture

this microscope has an electric field at tip of nanotube probe that monitors

this stain is the charge attraction that attaches color dye to organisms; basic dye attaches to � phospholipid heads

this stain uses more than 1 stain to differentiate between cell properties

this stain differentiates color that attaches based on thickness of peptidoglycan

this stain differentiates based on waxy coating of bacteria

this stain stains the background of things that can�t be stained
