Latest revision as of 05:11, 12 November 2021

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

Ecosystem

Summary
Family Connector Sensor Compatible

Meters

Memory
J DB25 Joule:

J8 J25

J50

J100


Power:

OP-2

S10

3sigma

FieldMax-TOP

FieldMax-TO

FieldMate

25LC320

(SPI)

Joule sensor: J25 is the most common followed by J50. J8 seems rare

Power sensor: OP-2 might be the most common. S10 seems rare


I've been calling these JSA due to "JSA-BNC", but that name might not be correct

LM

(LabMax)

DB25 LM-2

LM-10

LM-30

LM-45

LM-100

4omega?
 24C04

(I2C)

LM-P DB25 LM-P10 LM-P EEPROM looks slightly different than LM and in fact the LabMax-TOP user manual mentions these sensors are not compatible
PM

(PowerMax)

DB25 PM10

PM150

PM-P (PowerMax-Pro)

PM5200 93C46N

(SPI)

Even if it was electrically compatible w/ JSA EEPROM format is completely different


Ecosystems:

  • J DB-25 smart probes
    • Interface: DB25
    • Also known as JSA?
    • 3sigma, FieldMax-TOP, FieldMax-TO, FieldMate
    • 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
  • LabMax-TOP
    • Compatible with LM-, PM-, and PS- model thermopile sensors, and OP-2 and LM-2 model optical sensors. No adapters required.
    • Measures energy to 10000 pps and captures every pulse to 1000 pps with J-model and EnergyMax sensors
    • LabMax is not compatible with the legacy LM-P model energy sensors

PM official pinout for thermopile sensors


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

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

Newport 835

Newport project: http://hololaser.kwaoo.me/electronics/Newport835.html

I just happen to also have a few Newport 835s. Unfortunately my inventory is:

  • Newport 835, S/N 1477: calibrated for 818-SL, S/N 3190
  • Newport 835, S/N 1502: calibrated for 818-SL, S/N 3165
  • Newport 818-SL, S/N 3191

...which is close but doesn't entirely match. Dumped the EPROM / calibration data though in case I want to play with it in the future

Liconix 45PM

My oldest laser power meter. Meter + head both have S/N 9110014.

Completely analog / calibrated via pots.
