HySpex VNIR-3000n

HySpex VNIR-3000N utilize the same spectrograph as the other classical HySpex VNIR models. With a pixel size of 3.45µm, compared to 6. 5µm for VNIR-1800, HySpex VNIR-3000N will have less than 1.6 pixels per FWHM of the PSF spatially and less than 1.8 bands spectrally, ensuring that narrow band features will be resolved equally for all cameras. With 3000 spatial pixels, 300 bands and a noise floor of 2.4e-, HySpex VNIR-3000N will provide outstanding SNR levels in dark environments.

HySpex VNIR camera.

HySpex VNIR-3000N is developed for field, laboratory, airborne and industrial applications.The camera is offered with a USB connection, allowing you to operate the camera from any computer and reducing the cost of supplementing equipment.

To visualize that the camera has a wider PSF per pixel and band relative to our normal extremely sharp cameras, we have added an N for Nyquist to the model name.

Lab configuration

All HySpex cameras can be supplied with a rotation or translation stage, making them ideal for acquisition of hyperspectral images of static scenes, either in the field, in a laboratory or a clinical environment. The scanning is fully integrated in the camera control software.

Typical accessories used as a part of the HySpex laboratory imaging system are:

A typical field system consists of HySpex cameras mounted on a tripod and a rotation stage. Depending on user requirements, various rotation stage and tripod solution can be offered. These range from the standard solutions allowing horizontal scanning of two cameras, to high capacity solutions where tilted scanning is possible, and automated stages scanning the cameras in the XY direction.

Many users combine HySpex with their existing third party sensors, e.g. terrestrial LIDARs.

Airborne Configuration

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. A high performance rack computer is standard, but customized light-weight computers are available for smaller aircrafts, UAV's etc.

Industrial Configuration

Due to their extremely high acquisition speeds and real-time image correction features, the HySpex cameras are well suited for a wide variety of industrial applications such as material inspection or quality control.

In a typical industrial application, the HySpex camera is mounted statically above a conveyor belt using the belt motion for scanning.

Using the VNIR-1024 and 1 meter working distance as an example; the field of view is ~28 cm and the pixel footprint on the conveyor belt is 0.27 mm x 0.56 mm. With these settings and full spectral range and resolution, the maximum speed of the conveyor belt is 46 cm/s. The belt speed can be drastically increased if rectangular pixels are permissible, or by reducing the spatial/spectral resolution.
