Anyone selling a laser output power meter?
Do you have to get one for each wavelength, or can they be tuned?

Hi Steve
Have a look at this thread
http://www.photonlexicon.com/forums/...ad.php?p=19338
Tony (who makes and sells these) is a real good guy, I have one of his meters for holography and it works really well, you simply select the wavelength you want to measure from a simple menu. I also have a Coherent Lasercheck which is also a good quick way to get a reading from your laser. If you want better accuracy you'll end up paying for it; as accuracy improves so does the cost. However, for most purposes it's not really essential that we know how much power our lasers are putting out to the exact Mw (unless you are really paranoid ). Another thing to consider is that if you want REAL accuracy, you'll have to have your meter regularly calibrated and that's not cheap!

Hi..
Viasho sell one at $400.00 US$ . I have one its is a "broadband" job and covers most needs.
Its not a lab instrument but will do most things I need.
You can contact Frank at Viasho for more details also look at their website for details.
You can get him here:

I bought one of those Die4Things also and it works great. I think I got it under $200. Can't remember for sure.
i dont know, ask robin

Hello,
I have a used National Laser Company digital meter with two scales 0-20 mW and 0-150 mW. It was intended for air cooled Argon Ion. It seems to read slightly low on both scales but they agree. I would accept $150+ shipping. It is battery powered and in excellent condition. Phil Bergeron, 142laser, (813) 974-2378 Tampa, FL

I have both LPM-1 and Die4Thing and personally I think LPM-1 is only suitable for low powered lasers (<80mW) as it becomes inaccurate at higher power levels plus the sensor is very sensitive. You'll get slightly different reading if you hit different spot of the sensor. Die4Thing on the other hand is good at high power level but not very accurate at low but it's wavelength independent. They have their own pluses and minuses. Depends on what are you going to use it really.
Thanks for the feedback - having seen what's out there I think I might wait a while.
I probably need to spend a bit more money than I first thought.
