Buying Red-Sleds in UK (LOC diodes) or Pioneers red-sleds with 642nm.

Hmm I think I have an old pioneer 112 drive around here may have to harvest it and take a look.
thanks for the link.

Once you have "taken a look" could you let us blunderers know the results pls?

Still looking for red !!!!!!!!!!!!!!

Cheers

My bad. Found it at last!

Pioneer: 653.8 nm
or
" At least we can say the pioneer is operating at a significantly shorter wavelength that the Rohm,"

Desires always cloud the senses !

hi, I've been reviewing that data too. 653.8 and 660 are less than 1% apart, which falls well within the 1.5% measurement error that Hobbybob and I had recently with the same method. The excel sheet helps to estimate measurement error.

It may be a 660 diode after all, but it wouldn't hurt to test this diode again!
