I feel stupid for asking this but is there a trick to LPMing a laser when using a 405-G2 lens? I bought one from DTR for an upcoming build but was curious to see what kind of improvement it would give me on my ~710mw 445 but here's what I'm running into. Before LPMing any high power laser I always do a "cardboard test" to make sure I'm not going to smoke my LPM's sensor but this time no matter how I focused the beam it'd smoke the cardboard almost instantly. I have a feeling I'm just not hitting the right focal point but it seems I can't defocus it enough close to the aperture to not etch the sensor.
