I purchased two 2 in (50mm) circular lens which I need to run in series to collimate a beam of light. The problem is that they are circular (duh), and need to be secured. I was originally planning to fit them in a series of 2 in couplings but it turns out that plumbing fittings are a hair shy of 2 in. I think I will have to file them to make the couplings to get the lenses to fit but I wanted to know if there is some time of pipe out there which actually has a 2 in inner diameter before doing this.
>>2984054about 3:30 but I don't think I can make it.
>>2984054water pipe, like 2" pvc or black pipe, has an inner diameter of 2 inches. tube is measured by its od and pipe is measured by its id
>>2984054Use epoxy putty.
