The material used for the production of 84.5mm filters is commonly used worldwide for the production of
corrective eyeglasses, which shows the extraordinary optical properties.  While conventional optical glass
was  used in eyeglasses in the past, the trend of the 21st century is called organic glass, which offers
almost identical optical properties, as well as significantly is lighter in weight, more flexible, and more
resistant. Although these are some characteristics found in the production of eyeglasses, most
photographic filters which are currently on the market use this material as well.

Materials which are used in various areas of the military and aviation are usually known as the toughest,
highest quality and often unavailable to the general public. Organic glass is used in the manufacture our filters
and are also commonly used in military aircraft to cover the cockpit.  This material is highly scratch resistant
when washed, resistant to very high pressure, very elastic, light weight, and has excellent optical characteristic,
anti-reflective ability and more! Typically, the durability of these materials is appreciated in situations such as
combat pilots operating in difficult conditions and professional photographers shooting during harsh weather
conditions and or/time stress where filter can be scratched or damaged if it was made from basic plastic
material, not organic glass.  
                                                            

The material used in these filters (84.5mm) achieves the best features in a variety of other optical parameters
such as Abbe number with a value of 58, guaranteed minimum (hardly any) negative impact on the chromatic
aberration  (which is often a negative phenomenon cheap lenses) and more. If we combine the optical properties
with mechanical properties of flexible polymer / monomer we get almost perfect material, and that is what we
have, right?  
                                                            

While ordinary plexiglass or resin materials can be relatively easy to scratch, our organic glass is
completely a different case. Our filter material is characterized by extremely high scratch resistance and
common materials such as fingernails and sharp objects (plastic holder) make it almost impossible to scratch.  
This is another reason why it is used not only in correction glasses but also the military.  More information
about this type of scratch resistance of organic glass can be found in the FAQ section.  

Most ordinary glass breaks easily when it falls on the ground/floor, but organic glass is very flexible. Due to
the glass being flexible, if dropped on the ground/floor or you or handle insensitively, it most likely will not
break or shatter.                                                               

All of our products are completely hand-made in the European Union.  Using the most advanced manufacturing
processes, strict compliance adherence with European directives and legislation. Our trained team of technically
skilled manufacturing specialists provide a guaranteed premium quality product. Some might question why
certain products such as Swiss crafted watches are manufactured only in Switzerland and not outsourced in
Asian country for better prices. Our response is that highest quality products with high value, where every
smallest detail matters can be made only completely in-house, under the strict supervision of pedant specialists
working several years in hi-tech optics industry.  Simply high quality of our products and reputation of our brand
is much more important than reduction of production costs by outsourcing in developing countries (Vietnam,
Thailand, China) by less skilled staff.

We take pride in our work, in our products and we are proud to say they are all hand-made
manufactured in the European Union.   

                                                            

The following below are examples of some photography with the usage of the filter and without the usage of the filter.

Please note: The following photographs are not intended to showcase artistic qualities. This is not about artistic photos! The purpose of these photographs
are to show effect of filter in the strongest, raw and most intensive position / setting in order to show you its maximal possibilities/effect, while in real life you
will use filter in more gentle way, with less intensive effect / position of filter  - up / down to regulate amount of effect/ and exposure setting.

No digital post-production (Photoshop, plug-Ins, etc.) were used! Photographed with a digital camera Canon EOS in the RAW format.
