content: found this interesting looking itemwas advertised asLam RESEARCH / EXCELITE PAX-10 Precision-Aligned Pulsed Xenon Light Sourcewhat i saw was a setup of a light source and a spectrometerhad to find out what is it even if it was a bit expensiveand so..PAX-10 by excelitas xenon 10w light sourcenext was to find out what was the other unit, started to search some ofthe numbers and found some horiba / jobin yvon spectrometer images that look similarstill needed to find the specific model, i think it is the VS-7000-CCDbut the specific model configuration specs is yet unknownlooks 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 spectrometerpinouts:PAX-10:pin 1 -- Vinpin 2 -- Vinpin 4 -- Trigger -pin 5 -- Trigger +pin 6 -- Gndpin 7 -- GndSpectrometer: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 spectrometerand the light source from the main DB9a close look at the fiber optic tipxenon light source is the outer fiber bundlewhile the inner fiber goes to the spectrometernext step was to find the power needs which i knew was somewhere between 11-28vjust because it was written on the PAX-10first thing is to define the power polaritynext was starting at 11v and go up until ill find some signs from the usbat 23v i saw a green led light, rounded it to 24v as there isn't much differencein between if you consider the power tolerance and 24 looks also more logical then 23usb details:idVendor 0x0c9b Jobin Yvon, Inc.idProduct 0x000enext step was checking the light source trigger was specify as 5vlooks like everything is working ,coolwasn't a complete waste of moneymight even find a good use to this setup even if not in its current configurationfirst thing will be to replace the power plug with a more common onestill need to source the spectrometer driver so any help will be appreciatedto this moment didn't get any answer from Horiba / Lam RESEARCH

content: update:looks like Horiba / Jobin Yvon / Lam RESEARCHdoesn't offer any kind of support nor replaying to mail / contact formso if you encounter one of their products take that into countnext step will probably be hacking their spectrometertry to interface with the spectrometer ccdand see whats going on the open spectrometer market or just dim (do it myself)

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

content: 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

content: 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.

content: Found some teardown images of the Horiba units when hanging out on ebay. It seems the CCD used is Hamamatsu S9840Source:https://www.ebay.com/itm/114930886583?hash=item1ac26a27b7:g:qVAAAOSwmWhdW2zq
