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

Bandpass filters specifications

BP series: High bandwidth

BN series: Narrow bandwidth

BI series: Narrow interference bandwidth
