GENERAL HISTOLOGY

Detailed explanation-1: -The condenser is placed below the stage and concentrates the light, providing bright, uniform illumination in the region of the object under observation. Typically, the condenser focuses the image of the light source directly onto the plane of the specimen, a technique called critical illumination.

Detailed explanation-2: -Illuminator is the light source for a microscope, typically located in the base of the microscope. Most light microscopes use low voltage, halogen bulbs with continuous variable lighting control located within the base. Condenser is used to collect and focus the light from the illuminator on to the specimen.

Detailed explanation-3: -Incandescent Lamps-Incandescent tungsten-based lamps are the primary illumination source used in modern microscopes, with the exception of those intended for fluorescence microscopy investigations.

Detailed explanation-4: -The source of illumination for a light microscope is the small lightbulb located at the base of the microscope under the stage of the microscope. The light on these types of microscopes can be turned on when plugged into a power surge and the brightness of the light may or may not be adjusted.

Detailed explanation-5: -After passing through the vertical illuminator, the light is then reflected by a beamsplitter (a half mirror or elliptically shaped first-surface mirror) through the objective to illuminate the specimen.
