Overview
Sensor technology
Uncooled VOx microbolometer
Spectral range
Longwave infrared, 8 μm to 14 μm
Video scan
Progressive
Effective frame rate
4
8.7 Hz (exportable)
Thermal sensitivity
<50 mK (0.050°C)
Temperature compensation
Automatic. Output image independent of camera
temperature.
3
Scene Dynamic Range is specified at room temperature and may vary over ambient temperature. It is typically somewhat
reduced at lower operating temperature.
4
Lepton 1.5, 1.6, 2.0, 2.5 stream video at 26Hz with every 3 frames repeated (effectively 8.7Hz). Lepton 3.0 and 3.5 stream
segments of the images with effectively full frames at 8.7Hz. In this document, when referring to number of frames the
frame rate 26Hz is understood.
