Microscopy

What enables investigators to examine evidence at microscopic levels that would otherwise remain invisible to the naked eye?

Stereomicroscope

What kind of microscope combines two monocular compound microscopes, precisely spaced and aligned to create a 3D image for the viewer looking through both eyepiece lenses?

Stereomicroscope

Advantages of the ______
1. Ideal for evidence requiring moderate magnification (10x-125x)
2. Large working distance accommodates bulky items
3. 3D visualization enhances detail recognition

The compound microscope

What microscope represents the workhorse of forensic laboratories worldwide?

The compound microscope

What microscope combines multiple lenses to achieve high magnification (40x-1000x) while maintaining image clarity and resolution?

Compound microscope, Base & support, and mechanical

What microscope does this belong to, what part is it, and is it mechanical or optical?
“Provides stability, arm connects ____ to optical components”

Compound microscope, stage system, and mechanical

What microscope does this belong to, what part is it, and is it mechanical or optical?
“Platform holds specimens with mechanical stage for precise movement”

Compound microscope, focus control, and mechanical

What microscope does this belong to, what part is it, and is it mechanical or optical?

“Coarse and fine adjustment knobs for sharp image focusing”

Body tube, objective lenses, eyepiece, illuminator, and condenser

What are the optical components of a compound microscope?

Illuminator

In a compound microscope, what is this part?
“Artificial light, usually supplied by a light bulb, to illuminate the specimen”

Transmitted illumination

In a compound microscope, what is this part?
“When the light is directed up through the specimen from the base”

Vertical/reflected illumination

In a compound microscope, what is this part?
“When the light comes from above and reflects off the specimen”

Eyepiece or ocular lens

In a compound microscope, what is this part?
“The lens closest to the eye”

Monocular

A microscope having only one eyepiece

Binocular

A microscope having two pieces

Ocular magnification x objective magnification

Total magnification =

The comparison microscope

A microscope that allows side-by-side examination of evidence specimens

Polarized light microscopy

What type of microscopy reveals optical properties invisible under normal illumination, making it invaluable for examining crystalline materials, fibers, and other optically active elements?

The scanning electron microscope

What represents the pinnacle of forensic microscopy technology, providing magnifications up to 300,000x with exceptional depth of field and resolution capabilities?

Forensic palynology

A field of forensics which examines pollen and spores connected to crime scenes using microscopy as the primary analytical tool

Barium, antimony

The firing of a weapon can deposit gunshot residue containing __________ and ______ on the shooter’s hands.
