DIY Laser Power Meter

[chido]

Don't think so, I've seen Andy use a similar power meter before. Did he get one of those from a GB in another forum or something?

Will it be accurate to a few mw? That is all I need, I just want an idea of power. Is it a good deal or not?

 

[knimrod]

Is this power meter good or is it a peice of junk.

That sensor looks like a small (8.5mm x 6mm) peltier unit epoxied to a heat sink and spray painted flat black. The seller claims it "can test Lasers from 7mW to 1000mW output power in 1mW increments." I suspect the accuracy is marginal at lower powers and the damage threshold is very low.

is anyone still working on this? i can`t find any recent posts, and a lot of the parts on the parts list are no longer there.. especially on ebay.. i am very interested in making one of these! i love diy projects and this one looks like a lot of fun!

I am also interested to see if this is still going on, I would like to participate in the group buy if its still available.

These sensors are long gone, there was one seller who had a bunch but that was several years ago.

In 2-years we'll get another question asking about this.
