Beschreibung
Zusammenfassung:	The utility model discloses a near-infrared anti-reflection and transmission enhancing film, which comprises a PMMA board, wherein a titanium dioxide film is deposited on the PMMA board, and a silicon dioxide film is deposited on the titanium dioxide film. The near infrared anti-reflection and transmission enhancing film enables a reflectance value of near-infrared incident light to be maintained below 2% after being reflected by the anti-reflection and transmission enhancing film, and enables the light transmissivity of the incident light between 790nm and 910nm to be higher than 94% through adopting such a structure that the titanium dioxide film and the silicon dioxide film are deposited layer by layer and optimizing the thickness of the films. The near-infrared anti-reflection and transmission enhancing film is especially applicable to surfaces of mobile phone lenses and digital camera lenses.
