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

AI Thread Summary
Hot mirror (near) infrared mirror film is challenging to source, with searches on Alibaba and eBay yielding limited results, primarily for car window applications. The available films are often too thick and expensive for specific needs, particularly for NIR cameras that require bendable film. Users suggest exploring terms related to glasses makers or specific manufacturers like 3M and Fuji, known for producing IR reflective films. Concerns about visible light transmission leading to ghosting effects in camera images have been raised, indicating the need for more efficient solutions. Finding the right film that meets the required specifications remains a priority for users in this discussion.

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.

Thread 'Simple math model for a Particle Image Velocimetry system'

Hello togehter, I am new to this forum and hope this post followed all the guidelines here (I tried to summarized my issue as clean as possible, two pictures are attached). I would appreciate every help: I am doing research on a Particle Image Velocimetry (PIV) system. For this I want to set a simple math model for the system. I hope you can help me out. Regarding this I have 2 main Questions. 1. I am trying to find a math model which is describing what is happening in a simple Particle...

Thread 'Pentaprism with magnification, which surface is curved?'

I would like to use a pentaprism with some amount of magnification. The pentaprism will be used to reflect a real image at 90 degrees angle but I also want the reflected image to appear larger. The distance between the prism and the real image is about 70cm. The pentaprism has two reflecting sides (surfaces) with mirrored coating and two refracting sides. I understand that one of the four sides needs to be curved (spherical curvature) to achieve the magnification effect. But which of the...
