Whadda ya mean proper?
Optical ones only go up to a few 100mW possibly with ND filters.
Thermal meters are mega... (and proper) and go up to 10/100's of Watts.
- There is no such word as "can't" -
- 60% of the time it works every time -
maybe i meant like home made jobbies.
i want a proper power metre, although i suspect they will be out of my price range

If you need to ask the question 'whats so good about a laser' - you won't understand the answer.

Hi Andy,Ophir stuff is proper and come up on eBay quiet often. I just bought Marc's Coherent FieldmaxII.I've been looking for one for a while. I missed one on eBay a few months ago that went for a few hundred dollars. Grrrr.Also I missed one that was sold by a company that buys and sells second hand lab gear. Can't remember their name.Hofully the guys will chime in with some good models to look for. Keep checking eBay every few days, I forgot to look for a few weeks and missed a bargain. Even the Coherent field meters come up cheap when they are out of calibration because they are mind bendingly expensive to calibrate. They should still be plenty accurate enough for our purposes.Good luck and persevere.Kit
No doubt.....
You can get one of these....

All you need is 2 standard 9V batteries and a DMM and
you have yourself a Calibrated 5Watt OPHIR LPM....
But since you have to partially build it that may be called
a DIY LPM....
