Summary Introduction
Introduction:
Oil immersion is a microscopic technique used to get a better resolving power of a microscope. It is used to fill the space between the lens and the specimen to reduce the light refraction thus by increasing the resolution and numerical aperture. This is acquired by the immersion of the objective lens and the specimen in transparent oil, which has a high refractive index.

Microscopes are necessary for biological investigations because it allows us to study the detailed structures of an organism. 2. Microscopes must be handled with care and should be carried with both hands, one under the base and one at the objectives. 3. If you are tasked to mount a specimen of a head louse and view its overall morphology the best lens to use is the oil immersion objective lenses. 4. Objective lenses initially magnify the object’s image, form the real image and concentrate and send light rays to the condenser.arrow_forward
