Firecrest ND is a quantum leap improvement over all previous generation ND and IRND products and represents the technological state of the art in scientific light modification. These glass filters are hyper-neutral across the visible light spectrum and also remove more IR contamination than any other filter - making them IRND filters.

Firecrest is a radical departure in how ND filters are manufactured. Previous generation NDs were made by dying resin. Firecrest is not a dying process, it is a rare earth metal coating process that is applied directly to the glass through an electrolytic process.

On rectangular filters, the Firecrest coating is sandwiched between the finest Schott Superwite optical glass, increasing scratch resistance and longevity. Firecrest reduces all spectrums of light (UV, visible, near infrared and infrared) almost perfectly evenly.

 

These graphs show test results from an independent test performed at The Academy of Motion Picture Arts and Sciences (AMPAS). The test measured the spectral power distribution of tungsten light reflected off a spectralon target made of barium sulfate using a Photo Research SpectraScan Model 705 spectroradiometer. The results were graphed according to their wavelength (in nanometers) along the X axis, versus radiance (in watts per steradian per meter squared) along the Y axis.

In the top graph, the yellow line represents the baseline tungsten light reading reflected off the barium sulfate target. This graph illustrates the excellent filtration properties of both the ProStop IRND (shown in green) and the Firecrest ND (shown in blue). Both filters appear nearly flat from this perspective.

The second graph emphasizes the differences between the two filters by removing the baseline tungsten reading and zooming-in on the Y axis. On closer inspection, the graph shows the ProStop IRND strongly attenuating the near-infrared spectrum before returning to neutral attenuation of the infrared spectrum around the 730nm mark. Firecrest (shown in blue) performs perfectly linearly in the visible light spectrum, before completely eliminating the infrared energy at around the 700nm mark. Compared to the ProStop IRND (which is the previous benchmark in IRND filtrations) the performance shown by Firecrest ND is nothing short of revolutionary. Firecrest ND truly is the future of ND filtration for digital sensors. Results in-the-field confirm the test data. The new Firecrest ND is amazingly neutral regardless of the camera make or model used.

OVERVIEW

The Formatt Hitech Firecrest Neutral Density (ND) filter is a revolutionary new type of ND filter from Formatt-Hitech. Rather than dyed resin, Firecrest is a rare earth metal coating used to create hyper neutral NDs. The filters are made in different densities according to the level of light reduction from 1 stop to 16 stops of light. They are made from 2mm thick Schott Superwite glass, and the multicoating is bonded in the middle to increase scratch resistance. Firecrest Filters are neutral across all spectrums, including UV, visible, and infrared.
