Camera Origin of the D435if

[Cody-Vu]

Hello everyone,

I am using the Intel depth realsense camera D435if and I am trying to figure out where the origin of the RGB module is, specifically the z coordinate. According to the datasheet z coordinate of the starting point is -4.7mm from the front glass. I need to measure from the back of the camera, so my calculation would be (Value from back to front glass) - 4.7mm. Now I am missing the value from the back to the front glass. Online are only CAD models from D435i and D435f but not from D435if. Also when I use one of these CAD models somehow I can measure 2 values (24.95 or 25 mm). And on the official website the measurement of the depth is 25.8 mm. I need to be precise as possible.

Are there any official values regarding the starting point in reference with the back of the camera?

I appreciate any further information and thank you in advance!
