FIRST IN PHOTONICS
Over the last 35 years, SensIR has worked with hundreds of clients to help develop a wide range of Hyperspectral Imaging Solutions.
SensIR creativity and innovative optical designs are internationally acknowledged. Whether you need an individual services or complete systems development through manufacturing, SensIR engineers will work to develop your ideas or solve your problems on schedule, within budget and on-time delivery.
VPH LENS BASED SPECTROGRAPH
SensIR’s hyperspectral sensors are small, light, and rugged. The Lens Based Design uses VPH (Volume Phase Holographic) transmission diffraction gratings and proprietary lens designs to deliver exceptional imaging quality at low f/#’s. The high throughput design provides high signal-to-noise spectra at high frame rates. The VPH Gratings have the Highest Diffraction Efficiency with low Polarization Dependence.
SensIR's designs are line-scanning hyperspectral cameras often referred to as “Pushbroom Scanning”. One column of spatial pixels is collected per frame with each row containing full spectral data. Motion can be accomplished in two ways: either as an airborne deployment on a drone of aircraft, or translating the sample on a stage of conveyor belt. A third option is also available where pan-and-tilt or rotary stages allow a fixed-location hyperspectral sensor to scan a stationary object.
