Phase Contrast Equipment, PA • PB
The bright field observation method of microscopic examination can not be used for examining
colorless, transparent specimens since such specimens lack contrast. The phase contrast equipment,
therefore, was designed to provide such specimens with COntrast and thus make examination of
tivlng bacteria, c-ells and tissue possible.
Two kinds of light pass through specimen namely, undeviated light and deviated light.
Deviated lIght is
M
wave length slower than undevi.ated light. Contrast can be strengthened
through light interference
by
makins undeviated light
!4-
!Nave length faster or
srower.
This meth04
is highly convenient for observation ot the ecology of the specimen since it eliminates such trou·
blesome procedures as dyeing the specimen. The Olympus phase contrast equipment is highly
prized today since it has widened the scope of bIologIcal microscopic e)(:amlnatlon. What is more.
It is easy to handle.
