Yummy. More pics. Looks nice! It does look a lot better without the knob.
Will there be a grommet or something to protect the thermopile wires where they go into the meter? I am sure you already thought of that but figured I would mention it anyway since it immediately stuck out as something that could cause the wires to get chaffed.
EDIT. Hey... you covered up your secret formulas this time . I assume the answer was 47 though.
hahah.. you mean my math homework! I needed a fresh page, the equation was getting outta hand.
Actually addressing the thermopile issue. I've planned on having a simple mini-din connector in the housing. Ya know like your old school mouse and keyboard ps2 connections. The wire will then have the male equivalent and will easily unplug from the base unit.
Hi & congratulations the the three of you, I'm sure the LPMs will be a great success :beer:
The Pro enclosure's looking great! I'm not sure however what the USB one looks like... :-? Furthermore, I've been trying to figure out what kind of heads you will be using for both versions (USB & Pro) and the only pics of a probe I've seen so far look like Ken's using a Coherent head... (see below)
The coating is designed for high temperature operation - unless you purposely focus a laser of several watts or more to a pinpoint on the sensor, it will not be burned. You should also avoid using high energy pulsed lasers for obvious reasons.
Information on the thermopile will be released very soon. Have patience. The major difference of a thermopile and anything else I've seen is a thermopile sensor is like 300 grit sand paper with particulates actually inside the coating. I think this acts to distribute the heat more evenly through the layer into the thermocouple behind it. By distributing the heat away from the surface, it prevents it from burning the sensor. Now, that being said, you CAN burn teh sensor. If the sensor is rated for 1W and you hit it with a focused concentrated beam of 1W you will start cooking the coating. Especially if you've touched it and added oils or whatever to teh coating.
What is important to remember with anyThermopile sensor is to
not go over the Thermopile's max rating which is normally stated as
Watts/sq. CM... (Example 20W/sq. CM)
That means if your Laser beam has a cross section of 1 sq. CM you can
shine a 20 Watt laser on the Sensor's surface... but if your Laser beam
has a cross section of 1 sq. mm then your Laser can only be a Maximum
of 20,000/100 = 200mW...
