High quality optical glass is adopted for the production of all Daisee filters. Schott original optical glass is specially used for the professional Daisee Super Multi-coated filters series.
The optical glass has the function of anti-ultraviolet rays, which almost 100% light can go through within the visible spectral range. Reflection of light is less than 0.5%.
Daisee Testing Data indicates that:
Those filters without coating can reflect about 8% of the light, which hitting on the two air-contact surfaces of the glass; while the light loss of the multi-coated filters is only 0.5%. The multi-coating technology plays an excellent role in glare and light reflection. Daisee’s multi-coated filters decrease the possibility of glare and reflection from approximately 8% down to 0.5%, which means reflection is reduced 16 times.
DigitalMulti-Coating (DMC) of Daisee filter is not only an effective multi-layer coating, but also is durable enough to prevent the filter surface from being scratched.
The Characteristics of Water & Oil Repellent can effectively keep the filter clean and maintain the optical performance of the optical lens for a long time.
When testing this effect by an oil marker, the ink will be broken down into droplets by the coating.
Daisee adopted a new design where the filter glass is screwed into a high-precision retaining ring. This design can eliminate the possibility of loosening and maintain the balance of the filter, ultimately protecting both the filter and the lens.
All Daisee filters have adopted a unique packaging design, which is shock proof and drop resistant. It can effectively protect the filter, avoiding damage caused by external forces during handling and transportation
With high quality optical glass and polarized film made in Japan, more than 15% of the light can penetrate compared to the regular C-POL. Polarizing ability can reach 99% and it can block UV-400nm below effectively.
Digital Multi-Coating (DMC) for both sides is not only durable enough to prevent scratches, dust and water, but also reduces the extra disruptive stray light which exists among normal polarized filters without coating. The coating has been inspected by a salt water immersion test which meets the standard requirement for the optical coating.
The 5mm-thin frame is the perfect choice for super wide angle lens to prevent vignetting. The frame meets ROSH standard which fit environment protection requirements.
