HySpex VNIR-1800
The HySpex VNIR-1800 hyperspectral camera is developed for field, laboratory, and airborne applications.
HySpex VNIR-1800 utilizes a cutting edge actively cooled and stabilized scientific CMOS detector. This makes VNIR-1800 the ideal camera for high-end data acquisitions where high radiometric accuracy is required. The dynamic range of 20 000 ensures outstanding SNR levels even in darker areas of an image of highly dynamic scenes. With a max frame rate of 260 fps, combined with aberration-corrected optics and high optical throughput (f/2.5), HySpex VNIR-1800 offers a unique combination of
data quality, high speed, and sensitivity. A wide range of close-up lenses allows the use of the camera at working distances ranging from a few centimeters with a spatial resolution of 24 μm to infinity e.g. airborne remote sensing.

Laboratory setup
For lab and field use, a scanning stage is needed to scan the cameras and build the hyperspectral data cube of the scene. A user-friendly table-top lab setup with translation stage, VNIR-SWIR light sources, and close-up lenses can also be supplied for scanning of samples of varying sizes. The scanning speed is automatically controlled by the data acquisition unit, based on the selected lens option. The lab rack includes a camera adjustment platform, to facilitate camera focus adjustment when using different close-up lenses.
Accessories
Field setup
For field operations, HySpex supplies a range of high precision rotation stages tailored to fit the specific operational scenario.
Long-life Li-ion battery powered solutions are available for increased portability.
To ensure stable and reliable acquisitions in challenging field conditions, rugged and portable tripods are supplied. HySpex supplies a variety of tripods with pan/tilt heads that will accommodate the camera payload and rotation stage used.
Airborne Applications
High resolution and high speed, combined with low weight and power consumption, make NEO’s HySpex cameras very well suited for airborne data acquisition.
Position- and attitude logging systems (IMU/GPS) from leading manufacturers can be integrated and supplied with the cameras. Alternatively, the HySpex systems can be interfaced with the customer’s existing navigational hardware.
For airborne systems, NEO supplies dedicated software and a touch screen for ease of operation.
