Rejects the full wavelength of the Near-Infrared range that actually radiates heat.
Not only absorbs the special wavelengths of near infrared rays but also blocks the entire infrared wavelength range
near 780nm to 2500nm.
* 400nm~780nm: Visibile Light Transmittance Wavelength
* 780nm~2500nm: Near-Infrared(heat) Light Transmittance Wavelength
