All Baldur cameras are Nyquist cameras giving a spectral resolution of 2 spectral bands while capturing 4 times as much light as the classic systems. To ensure that the most information per framerate is provided, the spectral resolution is kept very close to 2 bands. Additionally, the spatial resolution of Baldur S-384 N is better than 1.5 pixels, yielding a very sharp camera. | HySpex VNIR-3000 N HySpex VNIR-3000 N is developed for field, laboratory, and airborne applications. HySpex VNIR-3000 N utilizes the same spectrograph as the other classical HySpex VNIR models. With a pixel size of 3.45?m, compared to 6. 5?m for VNIR-1800, HySpex VNIR-3000 N 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. The camera is offered with a USB connection, allowing camera operation 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. | Pika UV 330 - 800 nm Ultraviolet + Visible The Pika UV (formerly NUV2) is a hyperspectral camera that scans the Visible and Near Ultraviolet (VIS+NUV) spectral range. An optimized objective lens provides excellent imaging throughout the entire spectral range. Because halogen lights have low output in much of the NUV, Resonon offers an NUV lighting module to augment illumination for our desktop system. The Pika UV can be used in our airborne, laboratory, and outdoor hyperspectral systems, as well as standalone or integrated into your system. | Pika IR-L 925 - 1700 nm Lightweight Infrared The Pika IR-L is a lightweight and compact Near-Infrared (925-1,700 nm) imager. The small size and mass make it well suited for airborne applications, where it can provide invisible to the naked-eye contrast of outdoor features. For a compact, lightweight Visible light spectral range option, please see the Pika L. For a higher spectral and spatial resolution version of the Pika IR-L, please see the Pika IR-L+ imager. | HySpex SWIR-640 The HySpex SWIR-640 hyperspectral camera is developed for field, laboratory, and airborne applications. HySpex SWIR-640 offers high spatial resolution by using a unique MCT sensor. The FPA is cooled to 150K using a sterling cooler, yielding low background noise, high dynamic range, and exceptional SNR levels. The camera offers an aberration-corrected optical system with high optical throughput (f/2.0), the data quality, sensitivity, and resolution is truly state of the art. 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 32 ?m, to infinity for e.g. airborne remote sensing. |

We acquired a Resonon Pika XC2 hyperspectral imaging camera (visible to near infrared —VNIR) for my PhD project, in 2014 2015, following months of struggling with outdated hyperspectral imaging cameras prone to overheating and frequent malfunctions. This line scan (pushbroom) camera made my life easier: it was fast compared to the old cameras and reliable. Remarkably, nearly a decade later, it continues to operate reliably.
Featuring 1600 pixels per line and a fine pixel size, it captures data across ca. 462 wavelengths spanning from just below 400 nm to around 1005 nm (400 1000 nm), approximately 1.3 nm spectral sampling. However, the resultant file sizes are excessively large owing to the high spatial and spectral resolution. Depending on the number of lines scanned, managing these files can be daunting for saving, transferring, and processing.
Our experience with the camera’s hardware has been virtually trouble free. It consistently springs to action with a simple USB connection to the computer and activation of the lighting system.
The camera operates seamlessly with the Spectronon Pro software package, available for download at no cost from the Resonon website, requiring registration. This software facilitates camera control, stage movement, and occasional image processing tasks, which prove beneficial. The only issue is that light and dark images are taken before the imaging process starts and these are used for all the following images that can be a source of inaccuracy if one forgets to retake the images when scanning many samples.
The camera’s moving stage, measuring a modest 25 cm x 20 cm, and its lighting system (the older version in our possession) featuring four round halogen lights, present minor challenges. The lights tend to loosen easily and are difficult to adjust, although newer models now feature a linear lighting system (for a relatively higher price).
The camera’s smile and keystone are high according to what Resonon had reported (could not find it anymore to validate) and are bigger than the pixel size.
Considering its features and performance, the camera’s price is reasonable and competitive with Specim rival models. However, I do not have firsthand experience with Specim cameras to provide a direct comparison of quality.
