Pulsar introduces a new spec: sNETD will allow for easier sensitivity comparison among devices
NETD is the most popular spec to evaluate a thermal device’s sensitivity. Up until now, we used to share sensor NETD – the true, unadjusted value our manufacturer provides us with.
But with more and more manufacturers sharing system NETD, we decided to introduce this spec, too. This way, you can compare the devices more easily and accurately.
Quick summary:
- NETD – thermal sensor’s sensitivity provided by the manufacturer.
- sNETD – system NETD value after applied algorithms.
- Both NETD and sNETD values are now provided in the spec sheets of our devices.
So, from now on, when you open up a Pulsar device spec sheet, you’ll see two metrics: NETD, which is the original, sensor NETD and remains unchanged; sNETD, or System NETD, which is the sensitivity measure after applying internal algorithms and filters.
At this point, the image, its quality, and detailedness will remain the same – existing users will not notice any difference. But if you’re just considering purchasing a thermal imager and sensitivity is among the key factors for you, we strongly believe this will make things easier.
