Crystal IS Inc of Green Island, NY, USA, an Asahi Kasei company that makes proprietary ultraviolet light-emitting diodes (UVC LEDs), has augmented its Optan SMD (surface-mount device) product line for instrumentation with the addition of higher light output and wavelength specific bins (SKUs). The newest offering is the result of increased demand for UVC LEDs in fluorescence spectroscopy, imaging and biofouling control.
Like other Optan products, the UVC LED uses lattice-matched native aluminium nitride (AlN) substrates, which are proven to overcome limitations of other UVC LEDs in the instrumentation markets, Crystal IS claims.
With high light output at wavelengths from 250–280nm, new or improved example applications include:
fluorescence spectroscopy (label-free spectroscopy is important in biological cell imaging, tissue diagnostics and proteomics); flow cytometry (routinely used in bio-analytics and medical diagnosis, cell counting, cell sorting and biomarker detection); biofouling control (UVC LEDs can now be used for protecting larger sensors and those operating in environments that experience significant biofouling); and light source for catalyzing persulfate oxidation in TOC (total organic carbon) measurement (high levels of TOC can degrade water purification systems used in semiconductor and pharmaceutical manufacturing).
"Our newest Optan SMD bin has a higher light output and longer lifetime than any LEDs commercially available now," claims CEO Larry Felton.
Crystal IS is exhibiting the new LEDs in booth 4349 at the Pittcon 2016 conference & expo in Atlanta, GA, USA (6-10 March).
