NEW Triple Bandpass Filters for NDVI and ENDVI

Assess crop health quickly, inexpensively and in real-time using converted consumer cameras and unmanned aerial vehicles.

Palatine, Ill. (May 25, 2017) – Triple Bandpass Filters are tools that allow users to go above and beyond traditional Normalized Difference Vegetation Index (NDVI) indicators to reinvent the way crop health is monitored and to collect more information than ever before. Traditionally, true NDVI was used to determine plant health, which incorporates a camera with a red and (near-infrared) NIR filter and the equation NDVI = (NIR – Red) / (NIR + Red).

Bandpass Filters & Bionic Butterflies

MidOpt Near-IR Bandpass Filters aid in autonomous flying with indoor GPS

Palatine, Ill. (August 9, 2016) – Festo, a worldwide leader in automation (pneumatic and electrical control), technical training and development, has successfully implemented the first ever eMotionButterflies which show how several autonomous flying objects can move independently in an enclosed space without colliding.

“With the use of MidOpt BN850 Near-IR Bandpass Filters, active markers (850nm IR LEDs) and a 10 infrared camera set-up, Festo has demonstrated how the use of an indoor GPS and infrared cameras could be used as a guidance and monitoring system in factories of the future,” says MidOpt President Barry Warzak.

Midwest Optical Systems Announces StablEDGE™

Filters with performance efficiency uncompromised by angle of incidence

Palatine, Ill. (April 27, 2016) – Midwest Optical Systems (MidOpt) announces the release of a broad range of StablEDGE™ filters. StablEDGE™ is an innovative hybrid filter design that maintains critical spectral performance in imaging applications with short focal length lenses (<12mm) or angular-dependent lighting. In traditional filter designs, as the angle of light reaching the filter changes, the passband exhibits “short shifting,” and image contrast can be significantly degraded. Because the use of shorter vs. longer focal length camera lenses now predominates the market, MidOpt’s StablEDGE™ filter designs surpass those of all major filter suppliers in maintaining a desired width of passband in all applications, transmitting desired LED/laser diode illumination while blocking interfering light.
