Frequently asked questions
What is best between MWIR and LWIR wavebands ?
It all depends on what you want to achieve. Each bands have pros and cons.
For instance, a cooled LWIR surveillance system can show better atmospheric penetration upon certain atmosphere, compared to MWIR. But LWIR lenses need to be faster (smaller f#), due to the diffraction limit. This drives larger lenses, hence bigger, heavier and more expensive systems. MWIR can be a good trade off, but again, it depends on the mission to accomplish.
On measurement systems, it mostly depends upon the type of experiment and/or measurement conditions. We are here for you to help define the best suitable configuration. And if it’s a technology we don’t use, that’s also fine to let you know and give you workable answers.

What is the difference between a measurement and surveillance camera ?
Most often, a measurement camera aims to measure as accurately as possible and as fast as possible, but generally at distances of less than 1m.
Surveillance systems aim to detect an object or a living being at the greatest possible distance, up to 50km.
As both product lines are based on the same NoxEngine technology, crossed implementation leads to unique feature sets which benefit your application.
Can I build my camera from third-parties off the shelf components ?
Yes.
But putting together a lens and a detector will be just the beginning of a looooonnnng journey.
At Noxant, we are designing, manufacturing and servicing cooled infrared cameras for more than 30 years (yes, before the company was settled). Through this experience, we learned that providing a nice imaging, reliable and good working camera is not straightforward and requires a lot’s of mechanical and optical integration tricks, specific electronic architecture, advanced image processing, realtime system management. And all of this for all the cameras that will be delivered.

Midwave Infrared technology
Midwave Infrared (MWIR) technology plays a crucial role in thermal imaging, capturing radiation emitted directly from objects without the need for an external light source.

Longwave Infrared technology
For decades, infrared cameras utilizing Longwave Infrared (LWIR) and Midwave Infrared (MWIR) sensors have been a staple in military applications for detecting human activity.

Shortwave Infrared technology
Shortwave Infrared (SWIR) technology has emerged as a powerful imaging tool, offering unique capabilities that complement Longwave Infrared (LWIR) and Midwave Infrared (MWIR) systems.
