I wanted mine to last around 100 hours others have posted an early death at over 200ma drive current I'm getting 258mw @ 189ma with the Jayrob lens With about an hour of use I lost 4mw and now it seems to have slowed down and is very consistent in power out measurements on a flex drive The power...

Yes Sir

Yes the head is calibrated The repeatability of showing no reading when there is no radiation on the absorber Jim

No once the amplifier is calibrated to the head with a high quality op-amp circuit continual calibration is unnecessary. At first I was talking in general Thermopile terms, within 1mw is the repeatability with this head Jim

Here is how it works The Thermopile is a very sensitive device, it consists of the absorber which is a very thin graphite disc with a broadband coating on it that absorbs energy over a wide spectrum "190nm to 20um in this case" Behind this disc are junctions of dissimilar metals or...

Re: Ophir LPM from nospin - Awesome!

Benm Yes the Enclosures are as you see them Jim

The Thermopile can be configured in 4 different ways with part changes to adjust the total range of the head to a max of 20 watts. but it also changes the resolution throughout the scale, I figured 1mw resolution was a must for a hobbyist meter, that then results in a 5 watt total measurable...

Re: Ophir LPM from nospin - Awesome! No worries Jerry! Those Ophir Thermopiles are sweet, I just wanted you to know they are new and very accurate. I got a deep deal on them and using my 40+ years in electronics found a way to let everyone have a chance to enjoy them! Jim

Re: Ophir LPM from nospin - Awesome! Jerry They are not Surplus they are New Ophir heads With built in amplifiers Jim

Re: Ophir LPM from nospin - Awesome! Jerry Yes this is that Ophir head And this is entirely my design I too have never seen a Kenometer Jim

Re: Ophir LPM from nospin - Awesome! Great review Jay! I have always been stand up guy and I have I have a well designed, well built meter, and it only made sense to have the same kind of honest gentleman review it! Thanks Jay!!!:yh: To answer one of your Questions about the Zeroing of the...

Aluminum under that coat? Nice

I got this it to work! The SF-AW210 at 263mw works better than the LOC Red at 300mw I'm guessing because the violet burns better and makes more smoke then the red? I have had maybe 8 or more particles trapped a few times for a very short duration! 1 or 2 is more common. Quality of the lens and...

Wow I got it to work! The AW-210 at 263mw works better than the LOC 300mw I'm guessing because a smoke is denser than with the red? I had 6 particles trapped a few times! 1 & 2 is more common Quality of the lens and a very short focal length are key to success with my 405 Jayrob lens a 1" FL...

Free Laser Power meter for the best Tested design!!!!!!!!!!!!!!!!!!!!!!

Jerry I have been involved in electronics continuously since 1965 when I built a diode smart switch for a science fair entry I built my first laser in 1982 and I still have it today! in your posts the word we should be replaced with I as you don't speak for everyone here! Also these jabs...

Sounds like your a little paranoid Jerry...:mad: The details will be out very soon! Stay tuned Jim
