First quarter 2017 was very busy with a new IR telescope and optics for a space-qualified spectrometer, but we are now ready to take on new projects. Feel free to give us a call with your tough problems in optical system engineering, optical design, optomechanical engineering, and cryogenics.
We will be at the SPIE-DCS show next week. Text me at (484) 459-9589 to learn more about the latest hyperspectral technologies.
Meet our new product addition, the CHAI USB3 DAQ3
The DAQ3 can acquire imagery from 3 USB-3 sources, frame stamp with INS/GPS data and housekeeping data, control shutters and temperature, and store data to dual Solid State Hard Drives up to 2 TBytes. It is powered by the latest Xilinx FPGA and a high performance Single Board Computer. Interfaces are 28 VDC input, INS/GPS, serial interface, Ethernet interface, 3 USB-3 inputs, 1 USB-3 output. USB-3 extenders up to 7 meters included. Maximum I/O data rate is 5 Gbps. Storage is on 2 removable solid state hard drive, for fast swap out during field operations. Options include high speed fiber optic outputs up to 4 x 15 Gbps. Please call for the latest specifications.
We couldn’t find a low-cost dewar to test our new LWIR FPA, so we built our own and now offer that custom product to our customers. Our new LN2 dewars have both side-looking and down-looking orientation, and can adapt to most small to medium format FPA’s. These dewars also have fitting for pumping on the nitrogen, as to reach colder temperatures. We will configure the cold stop, cold finger, and lens adaptor to your sensor. Our current sensor card and electronics will drive the FLIR Systems ISC9705 or 9809 ROICs, with more custom electronics planned based on the Virtex-7 FPGA. Please call for other dewars, whether Liquid Nitrogen, Liquid Helium, or cryo-mechanical.

“A monolithic 640 × 512 CMOS imager with high-NIR sensitivity”

Remote sensing, biomedical and machine vision applications in the wavelength range up to 1100 nm can usually not be served by mainstream silicon sensors and the choice until now has been fully depleted (FD) CCDs or hybrid FPAs with inherent drawbacks like limited data bandwidth, large pixels and high readout noise. To solve this problem, we have developed a monolithic, fully depleted backside illuminated imager with 15 micron pixel pitch and VGA resolution on high resistivity silicon. The imager has high broadband quantum efficiency and supports frame rates up to 1000Hz. Latest results from packaged image sensors are presented here.
Exciting news! We just got our first images from our deep depletion, backside illuminated CMOS Image Sensor. This will open up many new opportunities in UV and Near Infrared Imaging. Stay tuned for more test results on quantum efficiency, dark noise, and frame rate, directly from the CMOS designer.
Specifically designed for hyperspectral imaging, the FBX-640×512 CMOS imager sets the bar for high performance VNIR hyperspectral imaging. Fully-Depleted, Backside Illuminated, eXtreme Performance, the FBX technology currently in the fab will create a new benchmark for science performance. High- broadband QE, high speed (>500 frames/second), and high sensitivity make this the ideal image sensor for remote sensing, microscopy, and machine vision applications. The next generation devices, the FBX 2k256, 4k512, and 8k512 will be the first in their class to offer digital output, significantly reducing camera size and complexity. Each is offered with or without temperature stabilization and cooling.
Brandywine Photonics’ CHAI WFOV telescopes are ideal for any of the CHAI aft-optics. All-reflective optics solve many of the problems inherent in refractive lens based solutions, such as low throughput and chromatic aberrations. Brandywine Photonics will also fit our fore-optics to legacy hyperspectral systems from other manufacturers upon request. Telecentric Telescopes with 20-mm, 25-mm and 38 mm are available for quick delivery while supplies last.
The CHAI V-2048 is based on the newest FBX image sensor technology. This hyperspectral imager is ideal for science applications requiring high SNR and the widest available swath. Low-distortion, all-reflective fore-optics make this instrument an ideal partner with coastal bathymetric and topographic LIDAR.
The CHAI V-640 is the instrument of choice for applications requiring a compact, low-cost, and high-performance hyperspectral imager. The V-640 integrates the most up-to-date Science CMOS image sensors with a powerful Offner spectrometer to achieve excellent image quality with high sensitivity. The V-640 form factor is suitable for multi-unit arrangements, including side-by-side, fore- and aft- viewing angles, and varying polarizations.
