Glass can bear extreme environment, but resin and glue line will deform in high and low temperature, which will influence the parallelism. ULTRA LOW COLOR CAST NiSi GND adopts our exclusive research and development gradual coating, the light from ultra violet to near-infrared light can pass through evenly. NiSi glass GND is durable, but the color of resin will fade, and glue line will easily come unglued. ANTI-GLARING Double sides anti-reflection coating,can avoid high reflection of metal film such as aluminum or chromium film. Double sides water-proof, anti-glaring and reflection coating,can lower the reflection and make the filter easy to clean. World's first Nano coating square optical gradient filter.
