Request InfoBlock EngineeringMARLBOROUGH, Mass., Aug. 19, 2010 — Block Engineering has announced the launch of a family of next-generation spectrometers based on widely tunable quantum cascade lasers (QCLs). The devices have both commercial and government applications. Three products have been introduced. LaserScan can analyze surface chemistries from a standoff distance of 6 in. to 2 ft; LaserScope is a high-performance infrared microscope; and LaserTune is a tunable QCL source used by researchers. According to the company, all three perform better than traditional Fourier transformed infrared (FTIR) spectrometers and are attracting interest among...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra April 2022 IssueFemtosecond LasersThe FSX series of femtosecond pulse width lasers from Photonics Industries International Inc. accommodates user-specified pulse widths for applications that require pulse widths from 350 fs to 20 ps....Photonics Spectra October 2022 IssueLaser Power MeterThe LabMax Touch Pro laser power meter from Coherent Inc. makes data acquisition and analysis for nW continuous wave lasers up to multi-kW, pulsed industrial lasers easy to access through an...Photonics.com 6/29/2023Compact UV LaserThe Spectra-Physics® Vanguard™ One™ UV125 from MKS Instruments Inc. is a compact UV laser designed for bio-instrumentation applications.
