At last! A TRG 105C Photodetector. Quote:
The TRG 105B Photodetector can directly measure the power of Q-switched laser outputs. To obtain a response from DC to 1.25Gc, the photodetecting photosensor element, the bias supply and the coaxial connector are part of one homogeneous microwave structure. Unit has a rise time faster the .3 nanosecond, output of up to 70 volts into a 125-ohm load, a DC bandwidth to 1.25Gc, and an Output impedance of 125 ohms.
That was from a listing way back in 2002, which I missed out on due to dithering. See first two pics. It was only $49, but while I was trying to make up my mind someone else bought it. I've never seen another one since.
Till this one came up. The next later model apparently. Bought it for $40. Last 3 pics. It's in the USA so it will take a while to get here via my reshipper. Fingers crossed it isn't broken, though I notice it's missing the front diffuser.
Ha ha, I offered $25, but on Saturday and I don't think the seller saw that yet. He did drop the price from 50 to 40. I'm really hoping he didn't see the offer and choose not to respond directly due to the thing sounding like broken glass rattling around inside or something. I couldn't take the suspense, and can afford $40.
I've also had no luck in all that time finding any data on it. Can anyone help with that?
