Bought this in 07 i think
Used maybe 20 times for a bunch of my lasers.
Have been collecting dust in my drawer for the past few years

I'm not sure how much these go for nowadays, I paid $220 for it soooo....
Looking for $150 shipped with tracking number or best offer
Accept paypal or money orders. *Will only ship to Canada/US*
If you happen to live in Greater Vancouver Area, feel free to come pick it up =]


What's included
- LPM-1 meter itself
- ND filter (for >100mW)
- the cable that connects it to comp


the tested laser is my WL core
feel free to post questions
i'll try and answer them lol

here are some links about the LPM-1

Well based off the info in the pictures alone, it looks as though it can handle 100mW without a ND filter, and possibly up to 500mW with a ND filter.

In case you don't know what an ND filter is, it is a Neutral Density filter and basically should allow a certain percentage of light through. I think they are "supposed" to be neutral and remove light evenly across all wavelengths, but they do not and therefore a calibration/percentage sheet if usually included in these sort of LPMs. Basically, say it is a ND2 filter, that means it passes light through by a factor of 1/2 (and say it is accurate for a red laser) - so if the meter reads 75mW, then the red laser is 150mW.

hmm that is a very good question...
I am really not sure
I never went past 200mW

back in the day, there were very few lasers that went past that range

any old school laser enthusiasts out there that remember the technical specs for the LPM-1?
