Life Sciences and Medical
Life Sciences is the use of laser technologies in non-therapeutic biomedical applications ranging from research to clinical diagnostics. Our mission is to enable and advance applications by leveraging our leadership in innovation for applications such as flow cytometry, cell sorting, microscopy, DNA sequencing and retinal scanning. Our key technologies in this segment include DPSS laser, diode laser systems, fiber pigtailed laser system, multi-color laser system and solutions for beam shaping.
Bio-Detection and Analysis
II-VI is dedicated to supply laser component and multi-color laser system for instrumentation market. The multi-color laser engine family is available in various wavelength pairs including 520/638nm, 488/638nm and other customer specific wavelengths. The multi-color laser engine family include single mode, multi-mode and polarization maintained mode with fiber output. The new innovative technology provides a compact and cost effective alternative to aligning two separate laser sources whilst providing long term reliability, low noise and exceptional stability than traditional technologies.
Bioinstrumentation applications, ranging from flow cytometry and cell sorting to microscopy, DNA sequencing and retinal scanning, use lasers to excite fluorescence from a variety of probe molecules. These fluorescent probes help researchers and clinicians perform a variety of important tests at both the cellular and molecular levels. Our key technologies in this segment include DPSS laser, diode laser systems, fiber pigtailed laser system, multi-color laser system and solutions for beam shaping.
II-VI’s RLAS-785 is a laser diode assembly that integrates the specification of narrow bandwidth, wide operation-temperature and high power. A unique technology is applied in this type of laser to lock the wanted wavelength, which guarantees not only ultra-narrow bandwidth (<0.1 nm) but also high side-mode-suppression ratio (SMSR) (typically 40 dB). The wide operation-temperature is realized by using a thermal-electric coupler (TEC) to control the temperature of laser diode, making RLAS-785 run well through -20°C to 50°C. Furthermore, these technologies help to achieve high stability (RMS<0.4%) and reliability of power and wavelength in long term, as well as long expected lifetime (MTTF>30000 hours). Products of three configurations, free beam, fiber coupled and module, are all available, promising its wide application in Raman spectroscopy, biomedical equipment and bio-sensor.
II-VI has an outstanding R&D team for DPSS laser, and customer-specified laser requirements are welcomed.
