Compared with conventional acrylic material or optical glass, PLANEXT®*1 produces superior or comparable optical performance.
Manufactured with high-precision injection molding, SEA&SEA has succeeded in producing a dome that has the same curvature as a concave meniscus lens.*2
The 210 AR`s optical distortion is as small as that of optical glass lenses and when used with an internal correction lens, the highest image quality of high-end cameras can be obtained Though the dome is made from plastic, it can be treated with stable AR coating. The 210 AR has Anti Reflective coatings to prevent internal reflection.
