RIX Optics Leap L3R

NETD stands for Noise Equivalent Temperature Difference, and it’s one of the most important specs in thermal optics.

What it actually means

NETD measures how small a temperature difference a thermal sensor can detect.

• It’s usually expressed in millikelvin (mK)
  
• Example: <30 mK means the device can detect temperature differences as small as 0.03°C

Pixel pitch is the distance between pixels on a thermal sensor. Smaller pixel pitch (e.g. 12μm) means more pixels and sharper image detail.

Why it matters:

Smaller pitch = better clarity, improved detection, and more compact devices.

Pixel resolution determines how much detail a thermal device can display. Higher resolutions—such as 640×512—use more pixels to detect heat, producing sharper images, clearer target identification, and better digital zoom. Lower resolution devices can still detect heat but often lack the detail needed to clearly distinguish objects.

Frame rate, measured in Hz, is how many times per second the image refreshes. Higher frame rates—like 50–60 Hz—provide smoother motion, less lag, and better tracking of moving targets, while lower frame rates can appear more choppy when scanning or following movement.

Duration

All RIX Optics complete devices come with a standard 3-year warranty.

For thermal imaging devices featuring 384x288 resolution detectors or higher resolution detectors, an additional 2-year extended warranty is available upon registration on the RIX official website.
