3/4″ InGaAs Camera 640×512, 15µ pixel, 400fps.

Why the EHD331KMB-UMV Pushes the Physical Limits
* The 15 µm x 15 µm pixel geometry (full-well capacity): Smaller SWIR sensors (such as modern HD-SWIR sensors with 5 µm or 3.45 µm pixels) have a very small photosensitive area per pixel. They capture an extremely small number of photons per unit of time. The 15 µm pixels of the EHD camera have a surface area that is several times larger. Even with ultra-short exposure times in high-speed operation (up to 400 fps with USB 3.0), they collect enough photons to generate a clear signal well above the noise floor.
* No thermal drift (TECless advantage): Since the camera operates in full-frame mode at 350 fps (GigE) to 400 fps (USB 3.0), the maximum dwell time for dark current accumulation (exposure time + readout time) is in the range of a few milliseconds. The sensor’s internal dark current simply does not have time to saturate the pixels to any significant degree.
The Result for Your Application
With the 3/4" InGaAs sensor, you avoid the “either fast OR sensitive” dilemma. You get a system that:
1. Is ready for immediate use, since there is no need to wait for a thermal stabilization phase lasting several minutes.
2. Remains compact and lightweight enough to fit easily into drones (UAVs) or tight industrial enclosures, as bulky heat sinks and fans are eliminated.
3. Delivers sufficient SNR (signal-to-noise ratio) to detect precise spectral differences in the 900 to 1700 nm range, for example in high-speed sorting systems (plastics/recycling or food).
