OPT3001: application of opt3001

Hi,

Light pipes can be tricky to design without a proper optical simulation to really understand how changes effect performance. What I can give are general guidelines, but this will need to be tested to check performance.

The biggest constraint will be the field of view set by hole size. This will be a function of the distance between device & hole and the diameter of the hole. In the case where the hole is tapered the worst case point should be taken. We have a FoV simulator tool (originally for OPT3006) and the attached document gives instructions for using the tool for OPT3001. Once we understand the FoV due to the hole (not considering effect of light pipe) this gives a baseline. Usually adding a light pipe can add some improvement to the FoV if properly designed, but the improvement is usually marginal.

In terms of the rubber and air gap I cannot give a direct answer here, but I would expect increasing the reflections inside the light pipe to improve performance. So if either the air gap or color of the rubber can help with this it could have an impact, but without simulation I cannot say with certainty.

Best,

Alex
