so rocket better or this blue one better? as in which one stronger? i've seen the blue one too but there's no name for it is there?
can.. IF you want to convert your camera into a very heavy paperweight.
in other words, don't use non-approved chemicals on your sensor.. its very delicate..
In addition, NSC will clean for free if you had paid for a CCD cleaning the previous month.
I went to Aus in Nov 06. Had the sensor cleaned before I went. But it got dirty during the trip due to the changing of lens. When I went back to NSC in Dec 06, they did not charge me.
Another 3 cheers for NSC!
Don't...
There is special wipe with solution for sensor. Even the size of sensor is matter for the swap.

I have been cleaning my D50's CCD using the Copper Hill method. The results have been terrific. I was just as afraid as touching the CCD like you initially but I have learnt that the CCD is tougher than it looks. In fact, we are only cleaning a piece of glass protecting the CCD, not the CCD itself. How tough is glass? I think quite tough. Contact me if you need help with the DIY, FOC of course!
It's not just another piece of glass. It's a piece of low pass filter with sub-micron features etched on it for anti-aliasing. That's why when you look at the reflection from the surface of the 'glass' you will see some diffraction also. I would not want to touch it.
I don't think it's coating. IMO it should be some sub micron Fourier features and it should be etched on the glass. I don't think it's just a simple coating. Ideally the features should be on the inside but we never know. :dunno:
Just found some info though.. the stackup for the AA filter is as follow..
Anti-reflection coating->IR filter->AA filter->Anti-reflection coating-> CCD.
So I guess it should be safe to clean the sensor just like cleaning any lens/filter, but just be sure you don't scratch it.
Ok. Thanks!
That's why it is not advisable to touch it without proper tools as the etched may scratched and damage :think: .

So I guess it should be safe to clean the sensor just like cleaning any lens/filter since the AA filter is actually on the inside, but just be sure you don't scratch the coating. :dunno: Usually I just blow the dust off.

Just clean your ccd once with the wet method. Blowing only does half the job. Nikon advocate, Thom Hogan, uses the wet method, look at his article. Really... don't be scared of damaging the CCD, with a pair of steady hands and the right tools, you will save yourself loads of money and worries over a dusty CCD.

My last round of CCD cleaning only took 20 mins...
wow that's fast !! :bigeyes:
thanks for your info, bro :thumbsup:
yes the low-pass filter is actually pretty hard. iirc, i saw in some site stating that the low-pass filter is actually of hardness 5-6 (10 being diamond and 5-6 hardness is around quartz). but that news was like 3yrs+ ago, so im not very sure if the changed the material used to make the filter. :dunno:
