What Is It?
Plain answers to the questions we are asked most: what these instruments are, what they measure, and how the measurement works.
We receive many questions about some of the science and topics that are part of the work we do in providing the Microspectrophotometer and Microspectrometer solutions for UV-visible-NIR microanalysis.
In this section are a number of articles we wrote to help people understand the work we do and some of the science involved in our high-tech industry.
The instruments
What the thing on the bench actually is.
- What Is a Spectrophotometer?A spectrophotometer is a device measures the intensity of electromagnetic energy at each wavelength of light in a specified region.
- What Is a Microspectrophotometer?A microspectrophotometer is a cutting-edge scientific instrument designed to measure the spectra of microscopic samples.
- What Is a Raman Microspectrometer?The Raman microspectrometer is a scientific instrument used to measure the Raman spectra of microscopic samples.
- What Is the Function of a Spectrophotometer?Spectrophotometry is a scientific technique used to measure the intensity of light either transmitted through or reflected from gas, liquid or solid samples.
The measurements
What a spectrum is used to work out.
- Film ThicknessThin films are layers of materials with thicknesses ranging from a few atoms to microns.
- Vitrinite ReflectanceCoal is composed of macerals, the organic components found in coal, kerogen, and other petroleum source rocks. Macerals include vitrinite, inertinite, and liptinite.
- Display ColorimetryColor of individual pixels and groups of pixels can be measured and compared using microspectrometers.
- MicrocolorimetryMicrocolorimetry is measuring the color of microscopic features using color spaces.
The samples and the optics
What the light is doing before it reaches the detector.
- Intrinsic Protein FluorescenceProteins, including protein crystals, can fluoresce without adding any dyes if they contain the appropriate amino acids in high enough concentrations and is excited…
- Ultraviolet Absorption of ProteinsProteins, such as those in animal tissue and plants, strongly absorb ultraviolet (UV) light at approximately 280 nm.
- Microscope Objective ClassesMicroscope objectives can be quite complex devices using either lenses or mirrors to collect and focus light.
