Molectron

Information on Molectron / coherent laser power meters. Ultimately for the ezlaze project. I'm mostly interested in pyroelectric heads for pulsed power.

Ecosystem

Ecosystems:

• J25 smart
  • DB25
• LM smart
  • DB25

Warning: J25 and LM are not compatible. There was a conversion box you could buy at one point though, so it might just be different EPROM format

JD1000

Power supply: CS-1203000 (12V @ 3A, center positive)

McMaster

J25LP sensor

Came with JD1000. BNC output but no 25 pin adapter

Back:

MODEL NO: J25LP
SERIAL NO: 238

Cable label:

COHERENT
Item# 1110748
Model: J-25MB-HE
Serial#: 0984E07R

Responsitivity
6.694e + 0 V/J
Cal 1064 nm

LM-10

LM-10 HTD 250-10600nm 10mW-10w 500mJ/cm2 10ns @ 1064n Laser

Relatively cheap impulse buy to compare EEPROM formats

3Sigma (eBay) meter

Came with CW sensor

3Sigma (dumpster dive) meter

Came w/ sensor + BNC adapter

Screen is messed up

Came with Lemo cable. Doesn't fit trigger ports or anything I can tell

JD1000 meter

Capacitor exploded when plugged in (presumably due to age). Didn't work after, although some lights turned on. Scrapped
