Measuring the properties of matter and energy
Excelitas lasers, lamps, optics and detection are used for a variety of applications in physics and material sciences including:
- Particle sizing
- Heterodyne detection
- Optical bench components
- Detector calibration
- Material testing
An ideal application for Excelitas detectors, particle size analyzers allow companies to develop better products faster. Understanding particle size through laser scatter detection is critical to understanding physical properties that allow scientists to characterize polymers, proteins and nanoparticles. Through detection of laser diffraction, physicists can use the patterns and intensity of scattered light that is directly proportional to the particle size.
Laser diffraction analysis is accomplished via a red He-Ne laser, a commonly used gas laser for physics experiments that is made up of a laser tube, a high-voltage power supply, precision mirrors and structural packaging. A lens is placed between the object being analyzed and the detector's focal point, causing only the surrounding laser diffraction to appear. The sizes that the laser can analyze depend on the lens' focal length, the distance from the lens to its point of focus. The angle of the laser beam and particle size have an inversely proportional relationship, where the laser beam angle increases as particle size decreases.
Excelitas' premium off-the shelf optics and mechanics present a noticeably superior performance for instruments and benchtop experiments throughout the sciences. These include our LINOS lens systems, laser diode modules, mirrors, polarization optics, zoom and microscope optics, thin film coatings, LINOS Faraday isolators, laser modulators and Pockels cells and more. Excelitas has a wide variety of precision mechanics such as LINOS Microbench™, Nanobench™, tube mounting system, positioning systems, mirror mounts, profile and rail systems, optical tables, spectrometers.
