EX. 1- The Microscope Flashcards
One of the basic tools in biology for studying structures of specimen that could not be seen by the naked eye
Microscope
The first microscopes
Light Microscopes
What principle is used in producing enlarged images?
Principle of the refraction of light rays
Earliest reports on its use was by who?
Pliny
Who fabricated the microscope and what did he discover
Leeuwenhoek; bacteria
What type of microscope includes two sets of lenses, the ocular, and the objectives on opposite ends of a closed
tube.
The compound microscope
What were the problems of early microscope
about focal distance which would decrease as magnification
increases
What did electron microscope used to produce highly magnified images?
electron beam instead of refracted lights
New concept recent developments in microfluidics and optics produced a new concept on design of microscopes.
Optofluidic microscopy (OFM)
What is the lens of the OFm?
metal coated sensor called Complementary Metal Oxide Semiconductor (CMOS)
Classification of the part of microscope
Optical and Mechanical
Parts which are made of metal
Mechanical Parts
These consist chiefly of special type of glass and aligned on optical axis.
Optical Parts
Magnification and band color of the scanner
4x (Red band)
Magnification and band color of the low power objective
10x (Yellow band)
Magnification and band color of the high power objective
40x (Blue band)
Magnification and band color of the immersion oil lens
100x (White band)
Immersion oil lens uses special oil
True
What do you use to clean the immersion oil slide
Lens paper
LINEAR OR THEORETICAL
MAGNIFICATION
product of the magnification power of ocular and magnification power of objective used
Formula of Magnification of Microscopic Specimen
X= LxW of drawing/ LxW of object
