1. How does an LWIR lens work?

An LWIR lens works by focusing infrared radiation onto the detector. The lens material must be transparent to LWIR wavelengths, typically ranging from 8 to 14 micrometers. When an object emits heat, it radiates infrared energy, which the LWIR lens collects and directs to the detector. The detector then converts this energy into an image, allowing users to see temperature variations in their environment.

2. Why is the 1280x1024 resolution important?

The resolution of 1280x1024 refers to the number of pixels in the image captured by the detector. A higher resolution offers more detail and clarity, which is vital for applications requiring precise temperature measurements or identifying objects in the thermal image. With 1280x1024 resolution, users can see more information about the scene, making it easier to analyze temperature differences and detect potential issues.
