How long infrared wavelength does D435i detect?

[TSuga2]

I'm considering using a special glass window to protect D435i from dust and liquid because IR light does not pass through usual glass.

To decide the material, please let me know the range of the wavelength which D435i uses.

The D435i is identical to the standard D435 model except for the added IMU component. So the D435's specifications for the IR sensor "cover material" will apply.

In the data sheet document for the 400 Series cameras, the cover material transmission wavelength range is stated as being "400 to 865 (Visible and Infrared) at 98% transmission rate or higher at all viewing and transmission angles".

Hi, MartyG,

Thank you for your quick response and it's very helpful for me.

I'm gonna use AR coated sapphire glass​ which has attached specification.

Thank you again from Japan.

Thank you very much for sharing the material that you are using. It is sure to be a useful reference for others. Good luck, and arigatou gozaimasu :)
