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 was to find out what was the other unit, started to search some of
the numbers and found some horiba / jobin yvon spectrometer images that look similar
still needed to find the specific model, i think it is the VS-7000-CCD

but the specific model configuration specs is yet unknown



looks like the power is shared between the light source and spectrometer,
signal is a DB9 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




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 so any help will be appreciated
 
to this moment didn't get any answer from Horiba / Lam RESEARCH

update:

looks like Horiba / Jobin Yvon / Lam RESEARCH
doesn't offer any kind of support nor replaying to mail / contact form
so if you encounter one of their products take that into count

next step will probably be hacking their spectrometer
try to interface with the spectrometer ccd
and see whats going on the open spectrometer market or just dim (do it myself)

I agree
I worked on Horiba gas analysers for a number of years
They provided no info at all.
Your best bet is to contact the USA office & talk to a tech.
Forget about Japan &  Singapore

Reviving an old thread. You may or may not have made any headway with this.
I recognize this unit from my recent work in the semiconductor mfg industry. I don't know why their eBay description was not accurate. This unit is called (By Lam Research) LSRi. Lam Spectrometry Reflectrometry 'i' (intelligent). It is a multi-mode optical endpoint device, capable of monitoring silicon wafer etching on the order of Angstroms, real time. Real splendid.
The reason I stumbled across this thread is I found one of these OESII CCD spectrometers on eBay for a stupid cheap price ($300 asking), while they are $30,000 USD new, and I was looking for anyone who was able to hack any Lam spectrometers. Their latter spectrometers are rather capable units, with a band of ~200nm-900nm IIRC, with what must be a 16bit CCD (in terms of intensity precision for each CCD pixel) and a sample rate of 10Hz.
As you must have already gathered, the CCD spectrometer communicates via USB and I believe can be powered by USB but also has that 4 pin (MOLEX?) connector on the opposite end.
The next most useful piece of information I could give you is good luck getting any response let alone technical information from Lam Research (These are supposedly made by Lam, not a third party, but that could be hogwash). It is near impossible to get any software or technical information from them outside of their Field Service Engineers, who work directly with their customers/semicon mfgs who titty feed them with tens or hundreds of millions of USD per year.
The easiest way to make use of that spectrometer probably would be to hack the CCD itself and process the outputs with your own ADCs. I have never had one open, so I'm unsure about how the CCD interfaces with its CPU. The spectrometer does spit out calibration information upon boot over USB (CCD gain 1, 2, 3 (I believe 3 gain coefficients), and C/offset).
Cheers mates

I'm not familiar with neither Lam Research nor their OEM spectrometers, but as a comment for people arriving here coincidentally, looking for cheap spectrometers, recently I found that there are bargains of Verity Instruments spectrometers on eBay (less than $800). I know them as I operate RIE tools with them installed as the EPD. the none -L postfix models use large, nice, TE cooled CCD detectors similar to Hamamatsu S7031. Thanks to the large (effective) fiber (bundle) diameter, these units have a very large etendue and are EXTREMELY SENSITIVE if your source is not as bright as a laser. When I measured the scattered light in a room with a distant CFL, my SD1024G appears to be more than x10 more sensitive than my USB4000. The -L postfix models are probably less sensitive but use the standard SMA fiber connector.
If anyone got one of those, you can PM me and provide some proof that you bought one, I can try to help you get started with them and provide some binaries in the SpectraView software as your IDA/GHIDRA exercises. The complete SpectraView software itself is kind of marked with it's customer name so I regret I cannot provide it unless you can convince me you are not going to redistribute. I'm also looking for newer firmware revisions as mine is quite old and with a awful bug when I want to run it at 500 Hz.

Found some teardown images of the Horiba units when hanging out on ebay. It seems the CCD used is Hamamatsu S9840
