This is a quick review of the alpha LPM from radiant.

The LPM itself is a standalone system (TEC based from the looks of it) LPM that runs off a 9V battery, which fits into the back of the unit, and is rated to be used up to 2Ws. This was why I bought the thing, as I needed something cheap, small, simple and portable that doesn't require a computer.

The meter itself:


green display:


The TEC glued to a black heatsink (heatsink maybe originally used for TO-220 devices from the hole mounts?)


And some meter shots with a pair of greens:

400mw O-like laser:


DHOM head: (the black barrel thing in the behind is just a random piece of junk to hold the wire down from flipping the TEC to the ground.)


Overall, radiaint and its staff built a very nice meter, and were pleasant and easy to deal with.

^ haha :D

For the duration that I've been a part of LPF I've yet to see them IN stock. I personally prefer Jerrys LPM with data logging, but if radiant was in stock, I probably would have bought one of them. It's really a preference and as a buyer I would rather see datalogging, but I don't plan to sell many if any lasers.

No, I was at the bottom of the home page where it was recent posts and I saw this. I then saw it was a review. Want to sell it to me anyways? :bowdown:

I have an Alpha and a Laserbee USB. For down and dirty I use the Apha and for more precise readings I'll use the laserbee.

Cool reveiw GBD :beer: and the price is right for the meter :)

Yep.. Ive bought it as a "base-line" meter so I have an accurate idea to callibrate.

Working on a DIY meter to read 5W-10W for some of my other lasers, 2W range of the alpha isn't enough.
