This Kood UV filter is made of optical glass and is multi-coated.
The core component in the composition of a quality filter is the type of glass used. Filters within the Kood Multi-coated series incorporate optical grade glass which undergo a ground and polishing process to ensure the highest level of picture sharpness that the lens is capable of capturing.
Kood's optical glass is treated with a broadband anti reflection coating which enable over 99% of available ambience light to pass through a broader visible spectrum from 450nm-650nm*.
*Standard multi-coating allows a narrower spectrum of light to pass through from 500-600nm
6 layers of anti-reflection coating on both sides effectively block out stray light from entering the camera sensor so that the highest clarity of digital images can be taken.
The optical glass are grounded and polished to achieve an ultra thin thickness of 1.4mm. Internal reflections are further minimised by applying a black ink coating surrounding the glass edges.
Precise CNC is used to machine the ultra thin frame to achieve a ultra thin height of 3mm. This enables the filter to be lighter and also suitable for usage on wide angle lens without vignette (darken of 4 corners).
