CRAIC Technologies has recently introduced their latest and most powerful instrument, the 20/30 PVTM microspectrophotometer. This microspectrometer is equipped with cutting edge technology that combines the latest advances in optics, spectroscopy and software to provide a rich user experience and superior performance with unprecedented speed and capabilities.
The Design and Working Principle of a Microspectrophotometer
The microspectrophotometer works on the basic principle of transmission microspectrophotometry and its design integrates a special optical microscope with an optical spectrophotometer. When light is emitted from the light source or a lamp is focused on the sample, measuring in the order of micrometers placed on the microscope stage, the transmitted light is collected by the objective and focused onto the spectrophotometer’s entrance aperture. The transmitted or reflected light from the sample is then measured for its absorbance, transmittance, reflectance of such microscopic samples.
Applications of Microspectrophotometers
While traditional spectrophotometers measure the spectra of samples on the order of 1 X 1 centimeters (cm), microspectrophotometers are a more modern type of scientific instrument that can measure the spectra of microscopic samples on the order of 1 X 1 micrometers (mm). The ability of the microspectrphotometers to non-destructively measure spectra of samples that are smaller than the thickness of a human hair, allows for these instruments to be used in a wide variety of applications and fields, such as forensics, chemistry, electronics and engineering.
For example, these advanced instruments could be used to measure the thickness of thin films present in semiconductors by an engineer, to analyze the dye in a single textile fiber by a forensic scientist or in the spectrum analysis of nanocrystals by a chemist. Microspectrophotometers can serve as indispensable tools in several production facilities for the quality control of several units such as color masks in flat panel displays and maintaining the thickness of semiconductor integrated circuits. In analytical laboratories, these highly versatile instruments have the potential to be used in the identification and quantification of a variety of microscopic samples that range from microfluidic kinetics to the qualification of gems or coal.
The “20/30 PVTM microspectrophotometer
The innovative and ergonomically designed UV-Visible-NIR Microspectrophotometer by CRAIC Technologies allows the user to measure the spectra in the ultraviolet (UV), visible and near infrared (NIR) range. The 20/30 PVTM microspectrophotometer facilitates the non-destructive analysis of a wide variety of samples for its absorbance, transmittance, reflectance, polarization, as well as fluorescence and photoluminescence. The latest technology integrated in the 20/30 PVTM microspectrophotometer allows the user to view samples with high-resolution digital imaging in the deep UV, in color or near IR, while the microspectra of the samples are being acquired. Additionally, the improved software, automation and ergonomics combined with the superior power of the instrument provides users with an unparalleled user experience while simultaneously offering a wide range of analytical capabilities. The specialized software modules for the 20/30 PV allow users to incorporate statistical analysis, spectra mapping and databasing into their image analysis procedures, thereby providing users with one of the most powerful and integrative technologies currently available on the market today.
By providing the research or industrial scientists with both real time and image capture of samples, the 20/30 PV is a highly versatile instrument that is both easy to use and maintain. Some other applications in which the 20/30 PV is expected to improve analysis sensitivity include:
- The verification of legal documents
- Structure determination of protein crystals
- Combinatorial chemistry
- Organic Light-Emitting Diodes (OLEDs)
- Microelectrochemical Systems
- Detecting impurities in both pharmaceutical and food products
