Data Table for Argus4
|Sensing Method||Bolometer using A-Si materials. The pixel resistance changes with temperature as it is heated or colled by the scene focussed upon it.|
|Sensor Type / Size||
ULIS 160x120 35µm pitch (P7030), controlled sensor temperature using Peltier.
ULIS 320x240 25µm pitch (P7130 and derivatives such as P7225), controlled sensor temperature using Peltier.
ULIS 320x240 25µm pitch (P7150)
ULIS 160x120 25µm pitch (P7050)
|Lens Parameters||Various f/1 lenses giving 50° field of view (except some variants). Fixed focus by moving lens at build|
|Dynamic Range / Control||150°C in 'ambient scene' settings. Up to 1100°C in low gain mode. No iris, dynamic range controlled by sensor electronic settings.|
|Display||3.5" colour LCD, driven direct|
|Sensitivity (MDTD)||Between 40mK and 90mK in 'ambient scene' depending on sensor and variant.|
|Power Source||6 x NiMH 1800mAh as standard but an 'AA' cell accessory was also available.|
|Power System||Battery voltage used internally, camera ~4W depending on Peltier loading.|
Network video (RTSP) available via accessory battery pack as well as supporting a number of other digital video accessories for recording or transmission
Analogue video output via battery connector using an accessory battery pack for most models, at 60Hz / 525 line NTSC only.
|Image Processing||Bolometer sensors require calibration and also 'on the fly' blank field correction using a periodic shutter.|
|Manufacturer Status||Later models are in manufacture and serviced. Some repairs (eg to sensor) now likely to be uneconomic.|
|Number and Years Built||High 1000's from 2006 - 2018+|
|Export Status||Dual use controlled under Wassenaar Arrangement unless a 9Hz limited type.|
|Publicity||Argus 4 datasheet
