Final answer:
The device that projects an image by directing light through a condenser onto an object is the light microscope.
Step-by-step explanation:
The apparatus that uses light concentrated through a condenser and focused through the object being examined to project an image is the light microscope. In general, light microscopy capitalizes on lenses to focus light on a specimen, producing an image that allows us to observe the specimen in detail. The condenser helps to illuminate the specimen, which is pivotal especially at higher magnifications where specimens reflect only small amounts of light, hence requiring increased intensity of light for proper visualization.
A light microscope uses light, concentrated through a condenser and focused through the object being examined, to project an image. Commonly used light microscopes include brightfield, darkfield, phase-contrast, differential interference contrast, fluorescence, confocal, and two-photon microscopes
