With a bandpass filter, you determine a specific wavelength bandwidth that should hit the camera sensor. This allows you to improve the image contrast, for example.
Features of the bandpass filters
- Increase the contrast for displaying the desired features
- Designed for use with all common LED wavelengths used in machine vision lighting
- Designed for use with laser diodes and the detection of UV-excited fluorescence emissions
- Protects systems from the variability of unwanted ambient light
- Eliminates the need for cumbersome and expensive sheathing
- Helps to counteract the negative effects of chromatic aberration
- Less susceptible to angle of incidence fluctuations than conventional interference filters
- Used to mimic LED lighting in tests to determine the optimum wavelength of illumination
for selection for an application - Helps increase LED light stability and longevity by facilitating operation at reduced power levels
For UV, visible and/or near-IR wavelengths - Indispensable for imaging in the UV and near-IR, as visible light should be blocked in these cases
Areas of application
- Industrial inspection, security,
Traffic control, medical and forensic applications
