Optical filters for machine vision have a wide range of applications.But how should one correctly choose a filter?
The choice depends entirely on the specific application requirements. Different types of filters serve distinct purposes:
- Visible light filters for routine inspection tasks
- Near-Infrared (NIR) Filters enable material penetration or night vision imaging
- Short-wave infrared (SWIR) filters for component analysis
- Ultraviolet (UV) Filters detect fluorescence or special markings
- Narrow Bandpass Filters ensure high precision detection by isolating specific wavelengths
- Long-Wave Infrared (LWIR) Filters are essential for thermal imaging.
By making the appropriate selection, optical filters can significantly enhance the performance and capabilities of a machine vision system.
