DESIGNED SPECIFICALLY FOR MACHINE VISION IMAGING
MidOpt bandpass filters have a broad, Gaussian passband to mimic and accommodate the entire output of the most common LED wavelengths …
- Great for testing monochromatic illumination
- A very high transmission: ≥90%*
- Excellent out-of-band blocking capabilities
- Double-side polished glass for exceptional parallelism and optical flatness
- Optical Bandpass Filters for imaging across the spectrum, including:
- Visible Bandpass Filter, UV Bandpass Filter, NIR Bandpass Filter, IR (Infrared) Bandpass Filter, SWIR Bandpass Filter
StablEDGE® TECHNOLOGY
MidOpt StablEDGE® bandpass filters are uniquely designed to be far less susceptible to angular shifting seen when optical filters are placed in front of short focal length (<12mm) lenses.
This feature is becoming increasingly important as today’s machine vision imaging moves toward more compact layouts, which utilize less space and force the camera and lens closer to the subject. As a result, short focal length lenses are now more widely used than ever before.

MINIMIZE THE EFFECTS OF SHORT-SHIFTING
Traditionally, as the angle degree imposed by the lens’ field of view increases, a filter’s passband will shift, which allows shorter wavelengths to pass (commonly referred to as blueshifting or short-shifting). In contrast, MidOpt’s absorptive filter glass design provides superb lower wavelength blocking, which will significantly reduce the effects of short-shifting.
