Nisi 150x170 Hard Nano IR GND8 (0.9)
PRODUCT
HIGHLIGHTS
Ø High
Definition: The glass is fine annealing environmental protection optical glass
H-K9L, it is specially used for optical lens.Double sides optical grinding and
polishing to make sure the high definition of glass. Glass can bear extreme
environment, but resin and glue line will deform in high and low temperature,
which will influence the parallelism.
Ø 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.
Ø 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.
Ø World's
first Nano coating square optical gradient filter. It's made from environmental
optical glass (H-K9L).
