Free first-order tools for field of view, pixels on target and DRI range — work out the optics before you commit to the hardware.
Angular field of view, IFOV and scene coverage at range from sensor size and focal length.
Open calculatorPixels across a target, ground sample distance (GSD) and angular size versus range and focal length.
Open calculatorDetection, recognition and identification range with a Johnson-style criterion and optional atmosphere/NETD signal limit.
Open calculatorEyereon designs EO/IR optics and imaging payloads matched to your sensor, spectral band and operating range. Tell us the target and we'll spec the optics.
