Bridging research with innovative products: Specim IQ – a compact, portable VNIR hyperspectral imaging camera
In late 2017, the Specim IQ Hyperspectral Imaging Camera marked a shift in the evolution of hyperspectral imaging from a mounted, scanning application to the possibility of a lightweight and mobile analysis method without sacrificing the high spectral resolution required to perform detailed and meaningful analysis. It presents itself in the style of the point and shoot cameras we take for granted, albeit with the benefit of taking hyperspectral images in the VIS-NIR spectrum (400-1000nm). Almost a year on from its original unveiling, the Specim IQ has found itself used in a number of applications that one would not have necessarily foreseen had it not been a mobile instrument, which begs the question: where will hyperspectral imaging find its next calling?
The imec snapscan system is a major breakthrough for hyperspectral imaging application research. The snapscan acquires high quality hypercube data-sets with unmatched signal-to-noise ratio and spatial and spectral resolution, in down to a few hundreds of milliseconds. The user friendly snapscan demo kit enables application research of the highest quality. It provides all key components required: the hyperspectral image sensor, camera, optics, piezo scanning, active cooling system, lighting, tripod mounts and imec’s most advanced hyperspectral imaging software.

The world’s first commercial light field snapshot spectral camera – LightShift™ – released by Surface Optics Corporation
Surface Optics Corporation has announced the release of LightShift™, the world’s first commercial light field snapshot spectral imaging system. Based on Surface Optics Corporation’s patented, plenoptic spectral imaging design, LightShift instantaneously collects spectral, polarization, and light field data at every pixel. LightShift’s multimodal datasets are captured and processed at video rates (28 fps), opening the door to spectral imaging for countless applications concerned with dynamic or time-sensitive environments.
“LightShift is the successor to line-scanning hyperspectral cameras because it images only those spectral wavelengths relevant to the customer’s application,” said Jonathan Dummer, CEO of Surface Optics Corporation. “Selecting feature wavelengths achieves higher accuracy, faster, than using the full spectra. LightShift’s pioneering opto-mechanical design also provides for the capture of polarization and light field information. This important information is not provided by other spectral imaging systems and can increase classification accuracy when combined with multispectral data. Compact, solid-state and operating at video-rates, LightShift is the ideal platform for researchers seeking to mature a spectral imaging solution for commercial or industrial applications.”
Keynote speakers have been announced for HSI 2018, the 7th international conference on Hyperspectral Imaging & Applications, co-located with Photonex Europe taking place on 10th & 11th October at the Ricoh Arena, Coventry, UK.
HSI 2018 brings together academic and industrial users to share their knowledge of innovations in hyperspectral imaging cameras, technology and applications. For 2018 key features are will be airborne systems and applications, innovations in snapshot hyperspectral imaging, health applications, data processing and deep learning.
Three international and leading experts in the field of hyperspectral imaging will be giving keynote presentations. Each presenting on subjects that highlight growth areas of interest and applications for hyperspectral technology.
Hyperspectral imaging (HSI) has been used for a couple of decades in applications such as satellite imaging, air reconnaissance and other not overly price sensitive markets. Classical Hyperspectral imaging cameras use prisms or grating as dispersive elements. These cameras are bulky, sensitive to misalignment and very expensive. The advent of alternative approaches makes HSI attractive for volume markets or even consumer products, for example cancer detection, precision farming, food testing in supermarkets and many more.
Delta Optical Thin Film A/S develops and manufactures custom Linear Variable Bandpass Filters (LVBPF) for mid-size and full-frame CCD/CMOS sensors (e.g. 25mm x 25mm or 24mm x 36mm). These filters offer very high transmission and are fully blocked in the light sensitive wavelength range of silicon-based detectors (200nm to 1150nm). The combination of LVBPFs with silicon detectors allows the design of very compact, robust and affordable HSI detectors that offer several advantages and benefits over conventional approaches:
- Huge aperture compared to grating and prism
- Higher transmission than grating and prism
- Short measurement time
- High suppression of stray light
- Excellent signal to noise ratio
Delta Optical Thin Film A/S welcomes requests for custom designed Linear Variable Bandpass Filters. Available for immediate testing are filters with the following specifications:
- Centre wavelength range 450nm to 880nm, bandwidth approximately 2% of centre wavelength, transmission 60% to 90%, blocking range 200 nm to 1150nm, blocking level OD4, size 24mm x 36mm
- Centre wavelength range 450nm to 850nm, bandwidth approximately 4% of centre wavelength, transmission 70% to 90%, blocking range 200nm to 1100nm, blocking level OD4, size 25mm x 25mm
- Centre wavelength range 800nm to 1000nm, bandwidth approximately 0.6% of centre wavelength, transmission >70%, blocking range 200nm to 1200nm, blocking level OD4, size 19mm x 8mm
- Centre wavelength range 800nm to 1000nm, bandwidth approximately 1% of centre wavelength, transmission >70%, blocking range 200nm to 1200nm, blocking level OD4, size 19mm x 8mm
The sizes are given as height x length, where height is perpendicular to the wavelength gradient and length is along the wavelength gradient. The filters can be diced to smaller sizes.

Pro-Lite Technology Ltd is pleased to confirm they will be attending the HSI 2016 conference at Ricoh Arena in October. We will be demonstrating the latest in the range of full frame, non-scanning, real-time imaging spectrometers from Cubert GmbH. This range includes multi- and hyper-spectral imagers used in a wide range of applications such as forensics, healthcare & medical imaging, food science and in UAV aerial mapping for agriculture, geology & defence. All the cameras provide clean spectral images out of the box without any moving parts, with no need for “push-broom” scanning or image combination following sequential filter shifts.
Cubert’s new Butterfly X2 imager combines two filter array sensors optically overlaid to cover the VIS-NIR wavelength range. The mosaic filters provide 41 spectral bands in the range of 470 to 1000nm creating full spectral cubes of 2000 x 1000 pixels x 41 wavebands at video rate speeds. The intelligent camera platform takes care of data acquisition, data fusion, storage and processing. This can then be combined with the industry leading Cube-Pilot spectral imaging software for data capturing and analysis.
