BaySpec’s OCI-UAV is an ultra-compact version of its OCI-Series Hyperspectral Imagers. The camera is designed specifically for use on unmanned aerial vehicles/systems (UAV/UAS) and similar platforms.
The ProEM-HS line of high-speed EMCCD cameras from Princeton Instruments make use of patented eXcelon 3 technology for low-light imaging and spectroscopy applications.
Headwall has introduced a new hyperspectral imager for very high resolution measurements of 0.1 nm over specific spectral ranges.
iBruker has released Inspire, an integrated scanning probe microscope infrared system for 10-nm spatial resolution in chemical and materials mapping.
Perception Studio is a software suite for hyperspectral data acquisition and processing, based on an extensible plug-in framework, allowing generic access to hyperspectral data.
Elucidating structural and compositional changes in plant tissues and single cells by Raman spectroscopic imaging
“Elucidating structural and compositional changes in plant tissues and single cells by Raman spectroscopic imaging” is the topic of the next article by Batirtze Prats Mateu, Barbara Stefke, Marie-Theres Hauser and Notburga Gierlinger. Understanding plant cells is important for the best use of plants in traditional and new applications. Raman spectroscopic imaging represents one of the best ways to unravel the molecular structure in the native environment of plant tissues.
Multisensor hyperspectral imaging as a versatile tool for image-based chemical structure determination
Hans Lohninger and Johannes Ofner describe “Multisensor hyperspectral imaging as a versatile tool for image-based chemical structure determination”. They describe the features of a software package that allows the combined analysis of hyperspectral data from different imaging techniques. This multisensor approach providing complementary information has many advantages.
Curtis Marcott, Tadashi Awatani, Jiping Ye, David Gerrard, Michael Lo and Kevin Kjoller give us a “Review of nanoscale infrared spectroscopy applications to energy related materials”. Fuel cells, photovoltaics and specialised polymers for fracking are all considered.
This article describes an application of spectral imaging for the differentiation of tumour and normal cells. The authors also introduce the concept of a spectral barcode, which has had success with some tissues and has potential in others.
Near infrared hyperspectral imaging for foreign body detection and identification in food processing
With continuing food scares around the world, food producers need every tool they can get to prevent contamination of their products at every stage of production. Hyperspectral reflectance imaging in the NIR combined with chemometrics shows much promise for the detection and identification of foreign bodies among food grains.
There are a number of approaches, and by combining FT-IR imaging methodology with microfluidics devices, the opportunity to study live cells by FT-IR imaging in controlled environments is now possible.
This Product Focus is on Imaging Spectroscopy; a number of companies have provided information on their key products, their applications and features.
“Measuring brain activity using functional near infrared spectroscopy: a short review” by Felix Scholkmann and Martin Wolf looks at the various methods for performing fNIRS and some applications that demonstrate why this non-invasive, safely applicable, portable and cost-effective method is now an integral part of the techniques used in neuroscience.

The TEL-1000 MW InSb high-performance infrared camera has been launched by Telops. The camera covers the 3.6 µm to 4.9 µm wavelength range and can be customised to cover an extended range from 1.5 µm to 5 µm. It can capture up to 200 frames per second at full frame (640 pixels × 512 pixels) and up to 600 frames per second when windowing (320 pixels × 512 pixels). It features patent-pending real-time processing and real-time temperature calibration. It can also be equipped with automatic exposure control in order to adjust the exposure time according to the scene’s dynamic temperature varions.
The SpectroCam multispectral imaging camera from Ocean Thin Films is now available with new analysis software. The software has a simple, intuitive graphical interface that allows users to quickly perform several image processing and analysis functions. Results can be viewed as live image output or saved to a variety of image file formats. The software processing is a useful tool for extracting MSI information and can even create colourised NIR images. In addition, the analysis portion of the software provides live, quantitative information regarding image intensity as a function of spectral wavelength for a user-defined image or image cross section. Applications include water quality measurement, product screening, machine vision, medical imaging, surveillance and authentication.
Telops has introduced the new improved Hyper-Cam Weatherproof which provides high-performance hyperspectral imaging capabilities but with an upgraded weatherproof enclosure. It has an extended temperature range which covers –20°C to 40°C and can be stored at temperatures between –40°C and 70°C. The system is IP rated, with a high resistance to rain and dust, enabling users to benefit from high quality spectral imaging without worrying about changing environmental conditions during field measurements. The upgrade enables the system to be easily used in a number of applications including stand-off chemical detection and identification, military target signature analysis, flare measurement and leak detection.
An imaging remote chemical sensing system based on the combination of a Michelson interferometer with a focal plane array detector. Developed for a wide range of applications it enables the detection, identification and quantification of a wide range of organic molecules in the atmosphere.
Micro imaging Raman system for applications in biologics (solids and liquids, comparability, biosimilars, batch release testing), forensics, pharmaceuticals, polymers and semiconductors. It can measure full spectra from 3200 cm–1 to 200 cm–1 including Amide I, II and III, S–S, S–H and C–H bonds. It measures 14″ wide by 11″ high and weighs about 10 lbs (~4.5 kg).
