OPT4003-Q1: Angled light guide for the sensor

Tool/software:

Hi, 

We are working on a device that has a profile of 4 mm and we are looking at the OPT4003 sensor for light sensing. Our problem is that we need to sense the light from the 4mm side profile so we need a light guide to direct the light from the side of the device 90° in to the sensor. 

So my question is do you have any recommendations on what light guide to use with the sensor?

    Hello Kristjan,

    What do you mean by the device has a profile of 4 mm? Could you share what the device looks like so that I can give a better recommendation for the light pipe design? Also, are you looking for a ±90° field of view, or are you only interested in light entering at 90°? 

    Thank you,
