The 95mm Coarse Thread Hot Mirror Water White Glass Filter from Tiffen is a stand-alone filter that blocks the infrared portion of the spectrum without causing any appreciable loss in the transmission of light. This filter can be combined with IRND (Infrared Neutral Density) filters.
The HMIRND filter incorporates Tiffen’s ColorCore technology, which sandwiches the coating within the filter. This technology allows you to clean the filter without damaging its surface. The filter is manufactured from fine and optically pure water white glass, which is grinded and polished to meet the highest possible standards of flatness and perfect parallelism.
