Dalsa Nano M2450 polarized camera: Resolving defects that are undetectable with traditional imaging!

Dalsa Polarization camera

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 …

Imaging Basics – Calculating Exposure time for machine vision cameras

calculate camera exposure

    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 …

CCD vs CMOS industrial cameras – Learn how CMOS image sensors excel over CCD!

CMOS Image sensors used in machine vision industrial cameras are now the image sensor of choice!  But why is this? Allied Vision conducted a nice comparison between CCD and CMOS cameras showing the advantages in the latest Manta cameras. Until recently, CCD was generally recommended for better image quality with the following properties: High pixel …

3-CMOS machine vision cameras bring color fidelity to the market at half the price as previous models

JAI- 3CMOS Apex cameras

Single sensor machine vision cameras use a mosaic filter placed on the sensor to create color images.  This is also called a ‘Bayer’ filter, named after the person who invented it.  However, color images from this filter lose resolution and color fidelity compared to ‘true’ color images.  Spatial resolution is lost due to interpolation, while …
