Where can I get some hot mirror (near) infrared mirror) film

Click For Summary
SUMMARY

The discussion centers on sourcing hot mirror (near) infrared mirror film specifically for use with NIR cameras, with a focus on the need for bendable film rather than glass. The user initially searched Alibaba and eBay but only found thick films intended for car windows, which were unsuitable due to their thickness and cost. They identified 3M and Fuji as manufacturers of IR reflective films, emphasizing the requirement for a film that reflects 850nm wavelengths without significant visible light transmission to avoid ghosting effects in camera images.

PREREQUISITES
  • Understanding of near-infrared (NIR) camera specifications
  • Familiarity with optical film properties and applications
  • Knowledge of infrared reflective materials, specifically 3M and Fuji products
  • Experience with sourcing specialty materials from suppliers like Alibaba and eBay
NEXT STEPS
  • Research 3M and Fuji infrared reflective films for specific applications
  • Explore alternative suppliers for hot mirror films suitable for NIR cameras
  • Investigate the optical properties of various infrared filters to compare efficiency
  • Learn about the effects of visible light transmission on NIR imaging quality
USEFUL FOR

Optical engineers, photographers using NIR cameras, and anyone involved in the design or application of infrared reflective materials.

I searched for "hot mirror film" on alibaba and ebay with no luck. Only seller I found was selling such films meant for car windows. For that reason it was too thick and a bit expensive because too big. I got one but yeah, it's too thick.

I figured I would find few Alibaba sellers for glasses makers who want to apply it to their shades or for car or office windows. Maybe I'm searching the wrong term?

PS. I myself need to reflect 850nm.

Needed for NIR camera, film and not glass as it has to be bendable.

Thank you. I have one such film made for car windows but it seams to pass about 5% of the visible light which results in ghosting (camera sees a very dim ghost of a different view behind the ir mirror because its vis spectrum filter isn't perfect either).

Is that okay? If the ordinary glass IR filters aren't themsleves more efficient than the answer would be yes.
