ABaT™ Unipolar Barrier Detector 3.3 – 3.5 μm Cutoff Wavelength

Download ABaT™ 3.5 micron detector datasheet

Amethyst Barrier Technology, ABaT™, is Amethyst Research’s new and disruptive infrared (IR) detector technology which offers low noise and high responsivity with excellent linearity over a broad spectral range in the mid-wave IR region. The advanced unipolar barrier architecture reduces dark current, thereby improving signal-to-noise ratio. The use of III-V compound semiconductor materials leverages mature and stable fabrication processes for superior manufacturability.

Detectors are available in TO-39 and TO-8 packages with active areas from ¼ to 1 mm 2. The operating temperature is optionally controllable by thermoelectric cooling.
