I want a design that hides the light emitting and receiving parts of the ZX Distance and Gesture Sensor SEN-13162
We are investigating by attaching an IR transmission filter to the IR light emitting part and the light receiving part of the sensor. If there is no reflective object on the sensor or if an IR transparent film is attached, the Z distance will be greatly reduced from 240 to 50.
Is there a problem in using the sensor? I would like to know the recommendations for covering with IR transparent film.
The sensors may have certain difficulties with the specific film in specific wavelengths, but that depends on the film and other external factors. We’ve never tried the same setup that you’re attempting so we can’t make any guarantees of the operation of the sensor. However, my best guess is that the film needs to be checked for specific wavelengths.
Thanks for reply.
The IR transmission filter I use is a filter that transmits 95% at 800 nm or more.
When using this IR transmission filter, the reason why the Z detection distance is greatly reduced is unknown.
I found your old models had light-receiving and light-emitting sections with light-shielding partitions.
Why did you not continue such a structure?

I guess it may be necessary to partition the structure like this.
In case of attaching an IR-transmissive film to the light-receiving and light-emitting parts of the sensor, it is presumed that we must have a structure that separates the light-receiving and light-emitting parts in this way. How about that?
