Longpass Filters
Simply and Efficiently Improve Machine Vision
Longpass filters transmit longer visible and infrared wavelengths and block shorter ones. They thus improve both contrast and resolution and separate colors in black / white. They are mainly used in monochromatic applications.
These filters are also suitable for color applications and machine vision tasks when multiple wavelengths need to be blocked.
Mount & Size Options:
- Threaded mount sizes: M25.5 to M105
- C/CS mount, slip mount for lenses without filter threads, step-up/step-down adapter
- Custom shapes and sizes; mounted and unmounted versions available
