Request InfoIridian Spectral TechnologiesImproved 1064-nm filters have been added to Iridian Spectral Technologies Ltd.’s Raman filter offerings. Noncontact identification of explosives and hazardous materials is an important application of portable and handheld Raman spectrometers. Excitation using 1064-nm sources reduces the fluorescence interference that is observed with shorter excitation wavelengths. Iridian has improved its 1064-nm laser line and long-pass filters by extending the operating range to 4000 cm−1 (1850 nm), enabling identification and analysis using features at Raman shifts beyond the fingerprint...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 5/17/2022Biomolecular Characterization DeviceThe Apollo biomolecular characterization device from RedShift BioAnalytics Inc. uses microfluidic modulation spectroscopy (MMS) technology to provide sensitive, precise measurements of biomolecule...BioPhotonics Jan/Feb 2024 IssueSpectral FastFLIM ModuleThe Parallel 16-PMT Spectral FastFLIM from ISS is a time-resolved spectral detector with parallel 16-channel digital frequency domain FLIM (FastFLIM) readouts for fast spectral FLIM data acquisition....Photonics Spectra April 2024 IssueUV LEDsThe WC2X2C40L6-325 and WC2X2C40L9-340-V1 from Violumas are UV LEDs made for biological applications such as biological analysis, spectroscopy, and sensing.
