hi lpf, selling my radiant x4 laser power meter with white case. includes extra long usb cable, tec sensor, and of course the radiant x4 board. software is available online but not needed.
price is $100 shipped conus. web img
I have one of these and it has never smoked when reading laser over three watts and focused to a spot no more than 3mm in diameter. I have even focused a 405nm beam on it with a spot not larger than 0.5mm without any harmful effects to the coating on the sensor. The data logging is top notch and easily loaded to any computer using most formats.
paul is right with regards to the durability of the sensor. it holds up way better than my old laserbee. i never put a focused beam on a sensor, day one stuff lol.
3.7 watts is the max it can read and the data logging is easy/nice.
