ND Effects With Adjustable Inner Frame
Rotatable inner frame allows users to adjust the ND effect within the range of ND2 (-1EV) to ND32(-5EV). Under the same setting, users are enhanced free from the restrictions of ISO values, aperture, and shutter configurations, to mere control the amounts of admitted rays, making larger-aperture, shallow-depth photographing doable even under strong lightings.
CPL Effects with Scrollable Outer Frame
Rotatable outer frame can adjust CPL effects and reduce the flares on surfaces of water bodies or glasses while making skies bluer and grasses greener (implies offering better color saturation). Reductions of ray splitting can also enhance the dimensions and contrasts between images.
Testings on Glass Surface Flatness
PV Values: The overall flatness-oriented(Peak-to-Vally)1 wave= 0.6328um
Miview filters can be stacked up to ten pieces per time; images will still be clear even after reflecting through forty optical glasses and twenty layers of optical materials.
(Side note:testing machine resolution ranges between 20 to 22)
Surface water drop contact angle is higher than 110 degree (proof of an excellent waterproof ability), and after a thousand times of abrasion testings, the degree of water drop contact angle is still higher than 100 (proof of an excellent abrasion resistance).
Compression strength 62.10kgf
Filters that pass completely stringent tests
Miview CND filters utilize multi-layer nano coatings even at the internal parts so fine that hardly observable. Comparing to the world-famous top-tier brands in the world, the optical quality of Miview CND is, in terms of glass surface evenness not any less excellent than German and Japanese well- known brands. The engineer of Miview utilized ten filters to photograph which was consisted of forty pieces of optical glasses and twenty layers of optical materials (linear and circular polarizer) and tested with a standard ISO-12233 resolution pattern, for which outstanding in sharp- and clearness in resolution is observed as result.
