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.

Headwall’s New Hyperspec® High Resolution Imaging Sensor Targets Vegetation Fluorescence for Airborne and Satellite Platforms
Headwall is announcing the availability of a new hyperspectral imager targeting very high resolution spectral measurements of 0.1 nm over specific spectral ranges which yield indicators of vegetative fluorescence to measure plant health. The ability of the new High Resolution Hyperspec instrument to analyze chlorophyll fluorescence emissions at extremely high resolution and high throughput gives remote sensing researchers and precision agriculturalists exceptionally valuable data from which to make environmental decisions. The new instrument is smaller, lighter, and more affordable than any other commercially available products and is optimized with robust packaging for airborne and satellite deployment.
“Our customers have been asking us for a high resolution hyperspectral imager targeting the small spectral bandpath ranges for use in extracting useful data with respect to chlorophyll fluorescence,” said Headwall’s CEO David Bannon. “Because remote sensing and the global crop industry is a multi-billion-dollar one, plant heath and physiology determined through hyperspectral imaging is a key investment for this market.” Water deficit is a major leading indicator of crops under distress, and there is a scientific link between this and chlorophyll fluorescence emissions.
The new sensor is based on Headwall’s all-reflective concentric optical design that uses very precise, very high diffraction-efficiency gratings for simultaneous high spatial and spectral resolution of < 0.1nm across the spectral range of the instrument. High efficiency, low stray light, and minimized smile and keystone distortion are fundamental to this design approach. Headwall’s all-reflective approach also means no transmissive optics, which makes the overall package not only more robust for space applications but lighter as well.
In extending technological leadership within the remote sensing market, Headwall announced availability of its new Nano-Hyperspec sensor for commercial UAV deployment. The low-cost hyperspectral sensor operates in the VNIR (400-1000nm) spectral range and includes onboard data processing and storage to minimize size, weight, and power constraints inherent with small, hand-launched UAVs.
The Nano-Hyperspec sensor can be combined with optional GPS/IMU capabilities to provide an airborne configuration that is small, light, and fully integrated. The total sensor package with data processor and storage weighs approximately 1.5 lb. (0.6 kg) and measures a scant 3 inch x 3 inch x 4.7 inch (76.2mm x 76.2mm x 119.4mm).
The VNIR sensor features 640 spatial bands and 270 spectral bands at a resolution of 2-3 nm. The frame rate of the Nano-Hyperspec is over 300 frames per second; usable data storage capacity is 480GB. Nano-Hyperspec is available in two options:
• OEM-programmable sensor configuration
• High-performance sensor configuration for end-users
“We designed Nano-Hyperspec to complement our performance-leading Hyperspec line of sensors and the growing market for small, low-cost, hand-launched UAVs,” explained Headwall CEO David Bannon. “The real innovation is the integration of the Nano-Hyperspec optical sensor and data processing module,” he noted. The optional GPS/IMU provides pinpoint correlation between actual terrain coordinates and hyperspectral data for a completely ortho-rectified hyperspectral data set. This functionality is just one of the many capabilities of Headwall’s Hyperspec III software.

Responding to strong demand for a versatile wideband hyperspectral sensor covering from 400nm to 2500nm, Headwall has introduced its VNIR-SWIR sensor package that features co-registered pixels for outstanding spectral fidelity across the entire range. The package is light (less than 30 pounds [13.6kg]) and small (approximately 15” x 15” x 8” [381mm x 381mm x 203mm]) for use aboard a range of airborne platforms.
VNIR and SWIR pixel co-registration plus aberration-corrected optics yields very high spectral and spatial resolution with repeatable measurement accuracy. With diffractive optics specifically designed and manufactured by Headwall, the hyperspectral sensor contains no transmissive optical elements or prisms that contribute to image aberrations in the form of stray light and cross-talk. Adding to image quality is the sensor’s very wide field of view and high signal-to-noise (SNR). Headwall has accomplished this by combining the high diffraction efficiency for the VNIR and SWIR spectral regions coupled with very high quantum efficiency of the detector subsystems.
“Our remote-sensing customers often need to cover both the VNIR and SWIR range but don’t have the payload capacity to deploy two individual sensors and separate data systems,” said Headwall CEO David Bannon. “We developed this co-boresighted and co-registered VNIR-SWIR sensor to meet those needs affordably while keeping size and weight low.”
Headwall’s VNIR-SWIR sensor is available for delivery approximately 8 weeks after receipt of order.
