iKan 4x5.65" Nano Infrared Neutral Density .3 (1-Stop) Glass Filter

SKU CH-S7N2-6AMVV

4x5.65" glass filter reduces light by .3 density while blocking infrared for accurate 6K colour

  • Exclusive dual-sided Nano coating controls infrared light pollution
  • 4mm thick optical glass with precision grinding ensures durability
  • Ultra-low color shifting maintains accurate color rendition
  • Anti-reflective coating reduces glare for cleaner 6K footage
  • Water, scratch and oil resistant surface protects the glass

4x5.65" Infrared Neutral Density Glass Filter

This 4x5.65" glass filter reduces visible light by 0.3 density while blocking infrared contamination. It is built for cinematographers and camera operators working with high-resolution digital cinema cameras that require precise color fidelity. The optical glass is cut, ground and polished to 4 mm thickness with dual-sided Nano coating.

Who this suits and who should look elsewhere

The filter suits productions shooting raw 6K footage where infrared pollution creates unwanted color shifts. It is not for photographers using smaller thread-mounted filter systems or anyone needing a different density value for their exposure control. Builders requiring a rectangular size other than 4x5.65 inches cannot use this filter.

The specification that decides fit

The 4x5.65 inch rectangular format determines whether this filter fits your matte box or filter holder. Verify that your camera rig accepts this exact width and height before purchasing.

Questions about this item

How do I install the 4x5.65" Nano Infrared Neutral Density .3 filter, and what step do people often get wrong?

Slide the filter into a compatible 4x5.65" matte box tray with the coated glass facing the lens; the step often missed is verifying the tray locks securely so the 4mm glass cannot shift during focus pulls.

What maintenance or replacement will the 4x5.65" Nano Infrared Neutral Density .3 filter need later?

Clean the dual-sided Nano coating only with a microfibre cloth and optical solution; replace the filter if the 4mm glass chips or the coating degrades enough to affect 6K raw colour fidelity.

What limit appears first on the 4x5.65" Nano Infrared Neutral Density .3 filter during sustained use?

Heat from continuous high-output lighting can stress the 4mm optical glass and dual-sided Nano coating, risking coating separation or subtle colour-shift before any mechanical wear occurs.
