Ocean Optics HR4000 HR4Pro VIS Spectrometer - 392nm to 840nm - Calibrated -

Description

Up for sale is my Ocean Optics HR4Pro spectrometer that was just wavelength recalibrated again in August 2021. You also get an electronic link to free Ocean Optics 1.6.7 OceanView Lite software so you can start taking measurements as soon as this spectrometer arrives to you.  This spectrometer works perfectly, even with Windows 7 or 10.  It reads between 392nm and 836nm and is setup with a user changeable 25um slit.  This spectrometer, in my opinion, has a good combination of better resolution and better sensitivity compared to other setups.  To see for yourself, please view my 5th picture showing a dim Ocean Optics HG-1 mercury argon light source (light source not included) using a 200um fiber cable (cable not included) running at a fast 10ms integration time. It's very sensitive!!  Thank you.
I have been an eBay member since 2001 with excellent positive feedback.  I am fairly familiar with this spectrometer so if you have any questions please scroll up and click "contact seller".  Thank you.
If you have any questions about the free software, please Google "Ocean Optics OceanView Lite 1.6.7".  Thank you.
