There are a few ways to tell if a window tint is ceramic:

Look for the manufacturer's label: 

If the tint is ceramic, the manufacturer will typically advertise this on the label or in the product description. Look for terms such as "ceramic," "nano-ceramic," or "infrared-reflective."

Test with a heat lamp: 

Ceramic window tint is auto tinting designed to reflect heat, so if you shine a heat lamp at the tint and notice that it is reflecting a significant amount of heat, then it is likely ceramic.

Check the color: 

Ceramic window tint is typically less reflective and has a more natural color than traditional metallic window tint.

 If the tint has a neutral gray or charcoal color and does not have a mirror-like appearance, it may be ceramic.

Consult with a professional: 

If you are still unsure, you can consult with a professional window tinting company or installer.

 They will be able to identify the type of tint and provide you with more information about its features and benefits.

Measure the Infrared Performance:

To measure the performance of an infrared (IR) device, there are several key parameters that can be evaluated:

Sensitivity: 

Sensitivity refers to the ability of the IR detector to detect even small changes in IR radiation. It is typically measured in units of noise-

equivalent temperature difference (NETD), which represents the smallest temperature difference that the detector can reliably measure. The lower the NETD, the more sensitive the detector.

Spatial resolution: 

Spatial resolution refers to the ability of the IR device to distinguish between objects that are close together.

 This is typically measured in terms of the size of the smallest resolvable feature, which is determined by the size of the individual detector elements in the device.

Spectral range: 

The spectral range refers to the range of wavelengths of IR radiation that the device can detect. Different 

IR devices are sensitive to different portions of the IR spectrum, and the spectral range is typically specified in terms of the minimum and maximum wavelengths that the device can detect.

Frame rate:

 Frame rate refers to the number of images that the IR device can capture per second. A higher frame

 rate allows for more rapid detection of changes in temperature, which can be important in certain applications.

Dynamic range:

 Dynamic range refers to the range of temperatures that the device can accurately measure. This is typically specified in terms 

of the minimum and maximum temperatures that the device can detect, and is influenced by factors such as the sensitivity and linearity of the detector.

To measure these parameters:

specialized equipment such as blackbody sources and radiometers may be required:

 the performance ceramic tinting of an IR device can also be affected by environmental factors such as temperature, humidity,

 and atmospheric conditions, which should be taken into account when interpreting measurements.
