The 4 x 4"Tru-Cut Ultraviolet (UV) Infrared (IR) 750 Blocking Filter from Schneider Optics has a completely colorless glass carrier coated with a number of extremely thin, partially reflecting layers with precisely computed thicknesses, similar to MC coating (multi-coating).

The Schneider Tru-Cut IR filter does not block by means of absorption, but by interference of the unwanted UV and IR radiation that is repeatedly reflected between these layers affecting the wavelengths on both sides of the visible spectrum with a steep cut-off. This filter is particularly effective when using high-density neutral density filters that help control depth of field. As the iris on the lens becomes larger, the danger from IR contamination becomes more prevalent. By using this filter, colors become more vibrant and true. 

The purpose of this filter is to block all UV and IR 'light' from reaching the sensor. This is particularly useful with some high end video cameras on the market that leak IR and produce magenta blacks in low light - this filter will bring the blacks back to black. The filter is clear when you look through it at 90° but when you look at it from an oblique angle, it has a magenta or cyan cast due to the complex coatings.

Used mainly on digital and video cameras with CCD sensors without an integrated IR protection filter, because the IR sensitivity of the CCD sensor would otherwise cause color changes and unsharpness
That unsharpness results from the chromatic aberration of the lenses that are only corrected for visible light
In the visible range, the transmission curve is very high and straight

      Comments about Schneider 4 x 4" Tru-Cut Ultraviolet (UV) Infrared (IR) 750 Blocking Filter:

      Never used a IR/UV cut filter before. I suspected my CCD equipped JVC GY-HM700U might be sensitive to IR polutiion.. I was right. In one take I noticed that the color and clarity was much better over not using it at all. This is a well made product and although looking through it with the naked eye it looks like a piece of clear glass, but it clearly blocked the ccd imager from the IR/UV polution.. Post editing reveiled the true result.. with the cut filter, clear nicely saturated HD content.. Stuff was there now that I never noticed prior to depolying the cut filter.. A must buy if you are out in brightly lit areas prone to UV and IR polution.. Works great in combination with ND gradiants..

        Doesn't look like it does much until you colour correct your footage. It's a must have in front of your lens.
