Revision as of 02:36, 27 October 2021

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

Ecosystem

Ecosystems:

  • J DB-25 smart probes
    • Interface: DB25
    • Also known as JSA?
    • 3sigma, FieldMax-TOP, FieldMax-TO, FieldMate.s
    • Intended to be used with J25, J50 power probes
    • I also have an S10 energy probe, seems to be compatible
  • LM DB-25 smart probes
    • Interface: DB25
    • Intended to be used with LM probes

Warning: J25 and LM are not compatible.

Other DB25 probes (none are known to be compatible):

  • Ophir
  • Laserpoint
  • Gentec
  • Newport

List of Molectron related power meters:

  • 3sigma
  • 4omega
  • FieldMate
  • FieldMax-TO
  • FieldMax-TOP
  • Fieldmaster

Lots of good info:

  • Energy Sensors Coherent J25.pdf
  • 2009_LMCCatalog86.pdf


There was a conversion box you could buy at one point though (thermal-smartsensor-adapter-data-sheet.pdf), so it might just be different EPROM format

  • JSA-BNC Adapter
  • 0012-2340: JSA-BNC Adapter for use with 3sigma, FieldMax-TOP, and FieldMax-P
  • 1056827: SmartSensor Adapter for use with 3sigma, FieldMax-TOP, FieldMax-TO,and FieldMate
  • Automatically configures itself to work with LM-model sensors

TODO: figure out pinout, EEPROM format so I can recal and upgrade adapters

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
