Oculus Rift DK1 and DK2 Spectra

Not really exactly a development question but I didn't know where to put that.

Would someone with access to a spectrophotometer happen to have the spd for the respective screens of the kits? Oculus / Facebook maybe?

Cheers,

KS

    Here is the spectrum of the DK2 showing the brightest white it can in 60Hz full-persistence mode. I hope this helps.
    I used the "Project STAR Spectrometer". I looked into it with my iPhone 4S. For getting more definition into the very dim scene I took the photo with the app "Average Camera Pro".

    Hello!

    Cheers for that! Unfortunately, the spectrum taken from a spectroscope will be quite dependant on the filter assembly front of the CMOS / CCD (Which usually has strong IR cut). I actually have a home built high resolution spectroscope and the 5d Mark II is for instance trimming quite a bit of the ultraviolet range and a fair bunch of the solar / sky spectrum. That's why I'm interested by a spectrophotometer!

    I didn't know about the Project STAR Spectrometer, I'll take a look at that, thanks! :)

    I also thought about that, but I can ensure you that the direct view into spectrometer with my eyes looks pretty much the same. But, of course, if you need precise numbers, this picture won't help you.

    Yeah I'm in need of precise values!

    The Rift apparently uses the same screen as Galaxy Note 3, so you might be able to find more info searching for that screen, such as http://www.displaymate.com/Galaxy_Note3_ShootOut_1.htm#Spectra

    Excelent find Dan! Most seaches I did were yielding results for the LG Spectrum... I'll try to contact the guy from the website you linked!
