Kunming Yulong Optical&Electronics Technology Co. has a high level technical team, which can provide you high quality coating services with long term. We have been working to improve coating film technology so that we can provide you reliable quality coating products with the lowest price due to reduce the cost. The glass main to block visible lght but transmit near-ir light centered around 850nm.
1) Suitable for sunlight and other bright light interference work; 2) Transmittance up to 90%, and the optical signal attenuation rate is small, effectively improve the working distance and light intensity; 3) Can be directly coating or glue in the infrared transmittance glass by the visible light, rapidly increase the cutoff rate, the vertical incidence in strong light without penetration, light transmission rate is less than 0.2%. And to ensure that working in large angle,and short wavelength shift phenomenon reduction. 4) More than 10 years’ experience in the production of optical filter, imported coating machine to produce, IAD ion assisted deposition technology and to ensure that the low temperature drift and film firmness stronger.
