Coherent Bioray Compact Fiber Ready Laser 640nm 100+mW Adjustable Focus SMA

Description

This auction is for a Coherent BioRay 640nm Compact Laser System.  (640nm 100 mW)
These are compact lasers which include a laser diode driver and rs-232 interface for monitoring and control of the laser.
This particular laser has a wavelength of 640nm.  Measured output was 100 mW after the fiber launcher.  Output will be higher if the sma collimator is removed.  There is a sticker on the laser of 637nm, so unsure if someone measured the particular wavelength as this.
This laser has 373 hours.
This model has the sma fiber launch option.  You can remove this to have a free space beam.
Tem00 mode.  Adjustable focus.
I am including the rst connector so you can make your own power/data cable.  If you need help let me know.
The laser and controller can be stacked on top of each other for a compact form.
These run off a 5V to 24V dc power supply.  The 'modulation' input is used to control laser output power as well as modulation.
You will need to supply a 0-5V signal to control 0-100% of output power.
I have these in other wavelengths such as 405nm, 450nm, 640nm, 647nm, 785nm.  Please ask if interested.
I will include a pdf copy of the user manual.  I will email you the control software 'Coherent Connection'
Please ask if you have any questions.
Buyer to pay shipping.
Thanks for looking!
BioRay is Coherent’s compact high-performance laser for Life Science applications with an elliptical beam output with a user-adjustable beam divergence (adjustable focus). With BioRay, the elliptical beam is easier to integrate into today’s particle measuring systems. With RS-232 control the laser power is adjustable as well as on-board diagnostics for operating hours, diode current, output power, temperature, and more.
Select StingRay and BioRay also include the μFocus and Fiber-Ready (FR) versions.
