Parts of the microscope

Parts of the microscope

It has tree sets of parts:

1. Stand
2. The mechanical adjustment
3. The optics or lenses.

Care of the microscope:

i.Examine all parts of a microscope before using it.

ii.The microscope should be moved always by holding its arm.

iii.Keep the microscope in a perfectly clear condition.

iv.After using oil immersion lens should be clamed by line or clearing solution.

vi.Before keeping it in the almira all the parts should be checked and cleaned with off cloth.     

Low power 10 х       

i.    10 objective lenses should be in the same line.

ii.   Condenser should be low .

iii.  Diaphragm should be partially closed.

iv.   Mirror should be plane.

v.    Eye should be taken near to eyepiece.

vi.  Then the coarse and fined adjustment should be made.

High power 40/45 х      

i.    40 objective lens should be in the some line

ii.   Condenser should be high.

iii.  Diaphragm should be partially closed on as like best.

iv.   Mirror shoaled be plane

v.    Eye should be near in the eyepiece then the coarse and fine adjustment is handled .

Oil immersion 100 х      

i.    100 objective lenses should be in the same line

ii.   Condenser should be high up

iii.  Mirror should be fully open.

iv.  Tip of the 100 objective lens should be dipped in the immersion oil which is plancedover the slide.

v.   Eye should be taken near to the eyepiece. Then the coarse and line

Maintenance of the microscope in the laboratory:

The important points of maintenance of the microscope in the laboratory areas are as follows:

9. Use the microscope erectly and handle it with care clear instruction should, be displayed close to the microscope.
10. Performances should be shocked by a compound person by using a specimen control slide.
11. Any problem in the use of the microscope is resorted immediately.
12. The microscope should be stored safly after using it.

Some thing not do of the microscope:

1. Never clean the lens of the object and eye pipe with ethanol.
