Q: What are the different types of IR lenses available, and how do they differ?
A: IR lenses are categorized based on the specific infrared spectrum they operate within:
- Near Infrared Lenses (NIR Lenses): 0.75–1.4 μm
- Short Wave Infrared Lenses (SWIR Lenses): 1.4–3 μm
- Mid Wave Infrared Lenses (MWIR Lenses): 3–8 μm
- Long Wave Infrared Lenses (LWIR Lenses): 8–15 μm Each type of lens is optimized for its respective wavelength range and is used for different purposes ranging from communication to thermal imaging.
