While waiting for the new set of FlexDrives to come in, I recently stopped by an industrial surplus sale and picked up some of these little 'Lazerdata 9000e' industrial super high speed barcode scanners.  They are intended for inventory and assembly tracking on an automated assembly line and would you believe back in '97 they retailed for $3000 each.  They can read much more than UPC label codes, see the manual for more info.
I tested out each one and it's reading barcodes and sending them to the rs232 port.

Inside is a gold plated hexagonal spinning mirror that could be used for 'liquid sky' effects or other experiements you can come up with.  Its speed can be adjusted via a pot on the PCB.  There is a tiny little TEC that cools a 9mm laser diode and mount which is electrically isolated with nylon screws.  The laser is collimated with a multi-element coated glass lens of high quality.  Also there is a spherical lens of very high numerical aperture that is focused through a removeable IR filter onto a high speed photodiode sensor.

On the control side there are many FET op amps and some high speed op amps including a 150MHz amp (for the photodiode sensor.)  There is a data processing logic control board which hosts a hitachi HD647180x microcontroller fed by 2Mb AM28f020 flash ROM.  Also a 1Mb fifo buffer, tms320C31 DSP, and a XC3130a FPGA, along with RAM (they were really serious about high speed scanning).

Power requirements are +/- 12V, 5V And can be fed into the unit via a VGA cable.
It's all housed in a red anodized aluminum case with AR coated window.

Lava,
That hard to pass up, but I've overdrawn my workload.

A bug zapper project come to mind because of the gold IR scanning mirror.

When CPU aquires a proper feed-back then switch on a 5w diode pulse. Vaporize!
 
Re: Laser barcode readers: liquid sky mini TEC len

What wavelength is the Laser in your Laser barcode reader units.. :-?
 
Re: Laser barcode readers: liquid sky mini TEC len

The wavelength is about 650nm red, <10mW. You can replace it with a high powered 5.6mm red and meredith 9mm-5.6mm adapter.

Price drop.. $30!
 
Re: Laser barcode readers: liquid sky mini TEC len

Could you post some pictures of the effect?
 
Re: Laser barcode readers: liquid sky mini TEC len

looks quite promising, i would like to see more of this unit.

It looks like a good housing for a labby.

Hey drlava... I received the Bar Code Reader today.... Thanks..[smiley=thumbsup.gif]
