• 产品名称: Laser Lens

  Introduction

  It is made of materials from Chengdu Guangming, and is applied to laser TVs, laser projectors and various other novel laser imaging systems by coating.

  Advantages

  1.Due to the adoption of laser damage resisting coating materials and ion assisted deposition, it has the transmittance attenuation of less than 0.1% after laser radiation;

  2.Films reaching zero absorption at specific wavebands has the transmittance of more than 99% at 440-470nm.

  3.By a peculiar high-transmittance material of Chengdu Guangming, the transmittance of lenses can be better improved.
