So, just a quick update...  I've started work on the cuvette tray assembly which is kinda the center of business right now....it holds the objective lens and mount...the beam splitter mount attaches inside...the display and keypad attach to it as well..

To arrange everything into the confined space...I've had to do a little reorganizing...  The Laser is now attached to the mirror directly, then the laser shutter is after that at a 90deg angle...then the beam splitter comes off of that into the drive bay where it attaches to the objective lens and faces the cuvette...I'll post updated renderings showing that asap... 

Meanwhile here's a couple renderings of what I've got going on it so far...lots to do...I have to work out the stepper motor rack and pinion for the tray, the tray slides... the cuvette holder itself (I don't like the one in the pics)... Also need to work out the attach points for the beam splitter and objective mounts... the display face needs some finishing, and so on...

Side view...with cuvette tray retracted...

A view with the cuvette tray open...

And a sneak preview of how it is sort of going to look in the ITX case....doesn't do it justice really...but it gets the point across for now...

That's all for the moment..but I am getting ready to get some schematics and stuff up for the controller board and display board...  More to come soon!
