Hello, everyone,
we are just in need of a laser diode module with super low beam divergence. we want to make measurement of a target at about 10 meters distance. In order to make sure of high precision, we just require the laser beam divergence is the smallest at the target.

I am searching online, and find this 532nm green laser diode module:

We need high precision dot targeting, about 10mm diameter would be fine, the maximum laser beam diameter is no more than 20mm.
Please help me confirm if this 532nm laser diode module is suitable for me need. Or you can suggest me the smallest diameter laser beam you have used. Thank you, and waiting for all your good suggestions.
