Microscope - Lab Report Example Bright field microscope is also called as student microscope. Bright field microscope can be used to study live micro organisms and pre- prepared slides. (Fixed stained smears). (Bain 2008). Bright Field Microscope: In this lab bright field microscope is used. The main parts of the microscope are lens system, revolving nose piece, stage, condenser and Iris diaphragm, light source, course focusing knob and fine focusing knob. The lens system consists of ocular and objectives. Ocular lens is the eye piece lens through which the specimen is viewed. Oculars have a magnifying power of 10 x in student microscope and the level of magnification is marked in the ocular. (Bisen and Sharma 2012). There are three objectives with different magnifying power. The scanning objective has the shortest magnifying power of 4x and it is the lowest magnifying power in a microscope. This lens is used to locate the specimen in the slide and to observe the large structures. The low power objective has the ma gnifying power of 10 x and used to observe the smaller structures at little detail. The high power objective of the student microscope has the longest objective and magnifying power of this objective is 40 x. fine details about the specimen are studied using this high power objective. (Bisen and Sharma 2012). The revolving nose piece has the objectives. The objectives with different magnifying power are chosen using this revolving nose piece. The stage is the flat surface on present below the objective on which the specimen is mounted. The centre of the stage has an opening through which the light passes on the specimen. (Bain 2008). The stage is mechanical and geared. The mechanical stage can be... In this lab bright field microscope is used.

This lens is used to locate the specimen in the slide and to observe the large structures.Ã The low power objective has the magnifying power of 10 x and used to observe the smaller structures at little detail. The high power objective of the student microscope has the longest objective and magnifying power of this objective is 40 x. fin e details about the specimen are studied using this high power objective.Ã The revolving nose piece has the objectives. The objectives with different magnifying power are chosen using this revolving nose piece. The stage is the flat surface on present below the objective on which the specimen is mounted. The centre of the stage has an opening through which the light passes on the specimen. (Bain 2008). The stage is mechanical and geared. The mechanical stage can be move to obtain the better resolution.
