OC mirror has number 61-490-043-30 on it's side. If these indeed are 488nm mirrors, can you suggest any place to ask for multiliners.
HR mirror says: 61-490-000-30 and 60815-91 on other side.
I'm running magnet from rectified variac voltage(not visible in picture), got 970µF of filtering there and it has about 20volts of ripple.
Currently limited at 200V as thats high as the caps are rated for.
