found this interesting looking item

was advertised as
Lam RESEARCH / EXCELITE PAX-10 Precision-Aligned Pulsed Xenon Light Source

what i saw was a setup of a light source and a spectrometer

had to find out what is it, even if it was a bit expensive

and so..

PAX-10 by excelitas xenon 10w light source

next thing was to find out what was the other unit, started to search some of

the numbers and found some horiba / jobin yvon spectrometers images that looks similar

still needed to find the specific model, i think it is the VS-7000-CCD

but the specific model configuration specs is still a mystery

looks like the power is shared between the light source and spectrometer,

signal is a DB9 plug that goes to the xenon light source and continue to the spectrometer,

usb belongs to the spectrometer

pinouts:

PAX-10:

pin 1 -- Vin

pin 2 -- Vin

pin 4 -- Trigger -

pin 5 -- Trigger +

pin 6 -- Gnd

pin 7 -- Gnd

Spectrometer:

pin 3 -- to main unit DB9 (pinout 3)

pin 5 -- Trigger +

pin 9 -- Trigger -

so looks like there is an option to trigger both the spectrometer

and the light source from the main DB9

a close look at the fiber optic tip

xenon light source is the outer fiber bundle

while the inner fiber goes to the spectrometer

next step was to find the power needs which i knew was somewhere between 11-28v

just because it was written on the PAX-10

first thing is to define the power polarity

next was starting at 11v and go up until ill find some signs from the usb

at 23v i saw a green led light, rounded it to 24v as there isn't much difference

in between if you consider the power tolerance and 24 looks also more logical then 23

usb details:
idVendor 0x0c9b Jobin Yvon, Inc.
idProduct 0x000e

next step was checking the light source trigger was specify as 5v

100Hz and then 1Hz

looks like everything is working ,cool :) wasn't a complete waste of money

might even find a good use to this setup even if not in its current configuration

first thing will be to replace the power plug with a more common one

still need to source the spectrometer driver

to this moment didn't get any answer from Horiba / Lam RESEARCH
