• 产品名称: Sighting Telescope

  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.
