Simply and Efficiently Improve Machine Vision

Bandpass filters transmit only one defined wavelength bandwidth and improve every vision system’s image contrast, repeatability and long-term stability.

Polytec’s bandpass filters from Midopt are divided into three series:

BP series: For standard machine vision and surveillance tasks

BN series: For outdoor applications or situations involving overwhelming ambient light

Bi series: For laser diodes or very narrow spectrum light source applications


Mount & Size Options:

  • Threaded mount sizes: M13.25 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

BP-series: High bandwidth
