I have an Ophir Nova Power meter with a 3A-P-SH thermal head and I love this meter. I don't have the RS232 cable assembly which retails for around 295.00 bucks which I am not willing to spend at this time. I was wondering if anyone had the pinouts for the 15 pin header connector so I may be able...

No laser, I repeat, NO laser should be purposely pointed directly into the eyes. This is foolish practice and amateur.

Rest assured, there is a driver module in that housing. You can't power a diode directly from 4 AA batteries. Well, I should not say you can't, you can but it would only last for a second before lights out!

I have killed Red diodes at 3.0 volts before, even with a well regulated current supply!

Oh, my bad. Yes I was just quickly going through new posts. Sorry for any misinformation.

Bushnell makes a series of range finders which are remarkably accurate and use a safe IR laser which allows accurate measurements out to I believe 1 mile with their newer units. I have the ARC1600 which measures out to 1,600 Yards. These use nice optics and an IR laser with an in-sight overlay...

I had a buddy came over one day with a basic 5mw-15mw 532nm laser pointer. He wanted me to break out my Artic III 1.5W to compare to his. We carefully selected an area of the sky which appeared to have no air traffic, and he fired off his little pointer, I then fired up the Artic III and...

I have a 3-Watt 365nm flashlight which works off of 2 Li-Ion batteries, and I have used it for quite some time without glasses. The general rule, Don't be stupid, and don't shine the light directly into your eyes or someone else eyes. Any prolong exposure of 365nm UV to your eyes will cause...

I am looking into building a meter that will gauge the amount of IR a laser is emitting. Before I get to involved in this project, are they any devices that currently exist to measure this emission? I know I can use varying techniques with infrared cameras to detect the presence of IR, but I...
