New 5 Watt Laser Power Meter

[Kenom]

I missed the $60 heads.. The cheapest ones I could find were around $230 brand new.

And these were new as well.. Purchased surplus from a medical company going out of business, they were never used once. Hell of a deal.

Sadly someone purchased all teh remaining stock.

I'm not trying to copy anything, I got a great deal on a lot of these Ophir Thermopiles
and came up with smartly designed supporting hardware to get the most out of these superb heads and the power needed to run it.

And a metal enclosure

As for how it zeros out

Here is what its doing
when you touch the heat sink or heat the sensor disc you are speeding up the equalization of temperature
difference between the sensor disc and the sink by changing the temperature of one of the junction sides
It doesn't effect the final value, that is achieved with a fine calibration adjustment.
Whether you touch it or not when you stop effecting the difference between the two
sides it will eventually settle to the calibration setting.

I'm an honest man and I've been involved in electronics since the sixty's
and built my first laser in 1982 and it still works!

This is a great and well built meter and I would never try to copy some others
achievements.

I built this unit without seeing any other hobbyist LPM's

I have the highest respect for you Ken!

OMG Ken

I just read the entire thread:

Kenometer laser power meter interest. LITE version *closed*

And I'm not sure what your talking about

The poor souls that sent you $ and waited for months for a meter that needs more
parts to be sent

Power supply issues that could lead to Thermopile damage

A hack zeroing pot that throws off the accuracy of the readings

overheating 5 volt regulation issues

Continual power supply modifications

asking people to buy a product sight unseen and untested

Why would anyone want to COPY that!

No sweat Ken

I meant what I said about the respect I have for you!

And your Kenometer lite units were a fantastic deal "the sensors were worth way more than the cost"

My meters were designed and built entirely from my electronics background and experience not from stealing from the competition.

I am honored to be associated with everyone who enjoys this hobby
