Infrared radiation is typically divided into three wavelength ranges. The exact boundaries and naming can vary depending on the source, but at Ceramicx the following standard is used:

• Short-wave infrared (SWIR): 0.78–1.40 μm, also known as near infrared (NIR) or IR-A

• Medium-wave infrared (MWIR): 1.4–3.0 μm, also known as mid infrared (MIR) or IR-B

• Long-wave infrared (LWIR): 3–1000 μm, also known as far infrared (FIR) or IR-C

This classification helps distinguish different parts of the infrared spectrum based on wavelength.
