FRSC 2600 CHAPTER 6, 8-10 - EXAM (2) QUESTIONS AND
ANSWERS WITH COMPLETE SOLUTIONS VERIFIED 100%
GUARANTEED PASS
Microscopy (in Forensic Science)
Can aid in a variety of evidentiary analyses that involve forensic biology, chemistry, and
physical comparisons
Eyepiece
A magnifier to view the primary image formed by the objective
Stage
The platform where you place your specimen or slide
Field of view
Area seen when looking through the eyepieces
Objective
Closest to the specimen, collects light from the specimen and forms a primary image
Condenser
Used to obtain a bright, even field of view and improve image resolution by condensing
light onto field of view
Illuminator
Artificial light used to illuminate the specimen
Focal length
The amount of distance required between the objective lens and the top of your object
, Resolution
The shortest distance between two points on a specimen that can still be distinguished
by the observer or camera system as separate entities
4 Common Types of Microscopes
Simple (single lens)
Compound
Polarizing
Electron
The microscope is an optical instrument which is used to
1. Visualize fine detail in the structure of an object
2. Provide a magnified image of an object
3. Measure length, angles, area of an object
4. Determine and compare optical properties (i.e. refractive index)
Compound microscope
A transmitted light microscope used for higher magnification and obtaining more detail
or better resolution (35x to over 400x), best for hair and fiber analysis
Comparison microscope
Two independent objective lenses joined together by an optical bridge to a common
eyepiece lens, best for firearms, tools, hair
Stereoscopic microscope
Two monocular compound microscopes properly spaced and aligned to present a 3D
image of a specimen, best for bigger, bulkier items
Polarized light microscope
