While traditional near-infrared Raman systems at 785 nm may allow automated, non-contact identification of several explosive substances, they are still prone to interfering fluorescence. The 1064 nm dispersive Raman system offers reduced interference and higher prediction accuracy, while preserving the rugged, field-proven architecture of conventional near-infrared Raman systems. This application note presents a study of explosive materials and subsidiary compounds analyzed using BaySpec’s 785 nm and 1064 nm dispersive Raman systems.
Using A Multi-Wavelength Confocal Raman Microscope For Non-destructive Pharmaceutical Ingredient Analysis
Characterization of the active pharmaceutical ingredient (API) and its distribution and physical properties in commercial medicine is necessary in drug research and development. Raman spectroscopy is gaining popularity as nondestructive, non-invasive, fast spectrum acquisition, and high reproducibility.
How To Properly Select A Laser Power Or Energy Sensor
Selecting a sensor to accurately measure laser power or pulsed laser energy can seem like a simple procedure, but often, the selection process is limited to choosing a sensor that only meets the range of power or energy to be measured, leaving out other essential criteria.
Aerial Hyperspectral Imaging: OCI Hyperspectral Imagers
BaySpec’s OCI-UAV hyperspectral imagers are designed for use on small UAVs to monitor the details of spatial, temporal, and spectral representation of ground objects. This app note discusses benefits of these imagers offer and delivers example images for multiple topography analysis.
Quality Assurance In Additive Production
Whether in research or in production, the laser parameters must be checked regularly. For this purpose, Fraunhofer Research Institution for Additive Manufacturing Technologies IAPT generally turns to the Ophir BeamWatch AM, which measures the laser beam without contact, is compact enough to be used inside the production chamber, and delivers measurement results quickly. This case study covers the full story.
Gentec-EO introduces the HP15KW-TUBE, a high-power detector for laser power measurement up to 15,000 W. This detector, a high-power water-cooled meter, is less sensitive to variations in water cooling temperature than other comparable products in the market.
High Speed InGaAs Photodiode Arrays: FCI-InGaAs-XXM Series
The FCI-InGaAs-XXM series of high-speed InGaAs photodiode arrays are designed with 4, 8, 12 and 16 channels. Each AR coated element is capable of 2.5 Gbps data rates exhibiting high responsivity from 1100 nm to 1620 nm.
V38-Line Scan Series For Complex Web And Surface Inspections
Line scan imaging is most commonly used for complex web and surface inspections and therefore, require a camera and lens with smaller pixel sizes and increased sensor resolution. Makro-Symmar, Micro-Symmar, Componon, and Apo-Componon lenses are designed for industrial machine vision applications and satisfy even the most stringent requirements of next generation 12k line scan applications.
Optical Filter Solutions For Datacom Applications
Iridian Spectral designs and manufactures optical filter solutions for long haul and metro access fiber-optic telecom customers. Iridian also applies the same proven thin film filter technology to address the growing needs for Datacom optical filtering providing wavelength selectivity to DCI devices such as transceivers and tunable laser assemblies (TLA).
Irradiance And Dosage Sensor For Narrowband And Broadband Sources: Ophir® PD300RM-UVA
Ophir offers the PD300RM-UVA irradiance and dosage sensor is designed for measuring sources at different wavelengths simultaneously in the spectral range, without the need to know the exact wavelength. This laser radiometer can replace a traditional radiometer that is calibrated to a single wavelength.
