What does a microspectrophotometer measure?
What is a Microspectrophotometer. The UV-visible-NIR microspectrophotometer is designed to measure the spectrum of microscopic areas or microscopic samples. It can be configured to measure the transmittance, absorbance, reflectance, polarization and fluorescence of sample areas as smaller than a micron.
How is a microspectrophotometer used?
Microspectrometers are used by analytical laboratories to identify and quantify microscopic samples ranging from the microfluidic kinetics, matching fibers or paints by a forensic chemist, the qualification of gems or coal by a geologist, the determination of the color of ink or paint by a process chemist and even the …
What role might a Microspectrophotometer play in a forensic investigation?
A microspectrophotometer can also be used to figure the chemical composition of something, like a paint chip. The spectral fingerprints gleaned from evidence collected from a crime scene can then be compared to samples collected from a suspect’s car, clothing, and so on.
Which scientific instrument may assist in the analysis of fibers by determining the visible and IR absorption spectrums of the fiber?
Fourier transform Infrared spectroscopy (FTIR) presents a nondestructive method to identify those fibers. FTIR can be coupled with microscopy presenting the ability to provide a forensic examiner with both detailed visual microscopic information and simultaneous material identification.
What is a visible light microspectrophotometer?
Visible microspectrophotometry is a very useful tool in the forensic analysis of many kinds of trace evidence . It combines a microscope with a spectrophotometer so that the light absorption properties of a very small sample can be recorded. They will absorb, transmit, or reflect specific frequencies of visible light.
What type of microscopy include the using of microspectrophotometer?
A microspectrophotometer can be configured to measure transmittance, absorbance, reflectance, light polarization, fluorescence (or other types of luminescence such as photoluminescence) of sample areas less than a micrometer in diameter through a modified optical microscope.
What is the visible light microspectrophotometer?
Visible microspectrophotometry is a very useful tool in the forensic analysis of many kinds of trace evidence . It combines a microscope with a spectrophotometer so that the light absorption properties of a very small sample can be recorded.
What is UV visible microspectrophotometry?
The UV-visible-NIR microspectrophotometer is designed to measure the spectrum of microscopic areas or microscopic samples. It can be configured to measure the transmittance, absorbance, reflectance, polarization and fluorescence of sample areas as smaller than a micron.
What are two methods that can analyze fibers without damaging them?
Two methods that can analyze fibers without damaging them are polarizing light microscopy and infrared spectroscopy.
Are fibers identified or individualized?
A fiber can be individualized to a particular piece of Fabric. It is easy to identify synthetic fibers because they have a perfectly round cross section.
What is the most used microscope?
Compound Light Microscope
Compound Light Microscope A compound microscope is the most common type of microscope used today, which mechanism is explained earlier.

How does a UV visible NIR microspectrophotometer work?
The UV-visible-NIR microspectrophotometer is designed to measure the spectrum of microscopic areas or microscopic samples. It can be configured to measure the transmittance, absorbance, reflectance, polarization and fluorescence of sample areas as smaller than a micron.
What is the resolution formula for a microscope?
The resolution formula of a microscope is: Depth of Field: This is the longitudinal resolving power of the microscope. It is the distance between the nearest object plane that is in focus and the farthest object plane that is also in focus. It is defined by the equation:
What kind of microscope does a Craic microspectrophotometer use?
CRAIC Technologies™ builds a microspectrophotometer that combines a UV-visible-NIR optical microscope with a UV-visible-NIR range spectrophotometer.
