Short Wave Infra-Red (SWIR) imaging is now more economical with the introduction of Allied Vision’s TECless Goldeye cameras. SWIR cameras open up numerous application possibilities for machine vision solutions, since they are able to detect defects that are not visible to the naked eye. SWIR cameras have an InGaAs (Indium Gallium Arsenide) sensor that detects …
The first Genie Nano camera model with a quad-polarizer filter using the Sony Pregius IMX250-MZR 5.1MP monochrome image sensor is now available. The Teledyne Dalsa Nano M2450 camera incorporates the nanowire polarizer filter allowing detection of both the angle and amount of polarized light. What problems can the Nano M2450 polarized camera solve? Polarized filtering …
In any industrial camera application, one key setting is the exposure time of the camera. In cases where this is set arbitrarily, the resulting image maybe blurry due to movement of the scene we are imaging. To maximize our settings, we can calculate the minimum exposure time to eliminate blur and maximize our scene brightness. …
