Infrared conversion of the nikon D5100 - DIY
May 16, 2012
I recently bought a D5100 body that I want to convert to be a Full-spectrum camera. To save costs (around 300 bucks) I decided to do the conversion myself. ( I live in Europe -shipping, customs, etc... +european converters like Makario in Germany cost a fortune.).
So far I found one less-detailed disassembly guide that helps a bit: http://www.ifixit.com/Teardown/Nikon-D5100-Teardown/5271/1
+ lifepixel's DIY guides on the D7000 and D5000 may give some hints.
One key question remained (besides a more detailed disassembly guide wouldn't hurt...): what are the dimensions of the replacement filter?
Has anybody converted/disassembled a D5100 yet?

I have a D5100 as well and will eventually modify it. However, I'm leaving it alone for awhile. If you should modify soon, let me know how it goes as I will be very interested. Thanks.

I'll do it in a month or so. First I test the camera if it has any issues to be fixed under warranty, then I improve my soldering skills a bit...

After all the waiting I can report full success!!!
Some additional - important! info for the iFixit guide:
1. The hidden screws: two are on the right
two in the backside (one hidden under the soft-rubber diopter-scale!!!):
2. To release the motherboard 4 cables have to be desoldered:
3. The sensor is attached with a grey plastic (heat spreader?) tape, you dont have to release the tape (you can't unless you cut it or you disassemble the entire camera). to release the sensor, you have to unscrew 5 srcews and play a bit:
4. The dust filter includes a schott BG39 like layer causes all the pain for IR and Astrophotographers. fortunately its easy to remove by desoldering its contacts:
The result:

(P.S.: The IR shot was done through a 18-105mm kit lens at f/22 and 1/50sec using an el cheapo 720nm filter)

Can you still clean the sensor with the filters removed? That's a lot of dust in that IR shot.

This question has been asked before in the forum - I think in respect of the D5100 - so do a search and you may find out more. I seem to recall that the dimensions are kept secret, so you would have to disassemble and measure the filter for yourself.

Re: Déjà Vu
As you can see above, I did disassemble it:) It seems, that the sensor is covered with a clear glass sheet (the system is quite sensitive using the 850nm filter), not a concern anymore. The problematic part (BG39) can be removed easily while the sensor stays protected.

The built-in sensor cleaning of course doesn't work, because you remove the glass sheet belonging to it, but you can still clean the sensor with a cotton swab wetted with a little isopropanol or ethanol. yes, I see, my first shot was quite dusty but I managed to remove all the dust with isopropanol. Manual exposure to B, and for being on the safe side, no direct light on the sensor - i didn't want to overload it. You probably have to do it a few times in order to get rid of all the dust.

One issue remained: infinity focus. I am checking suppliers for a multicoated 29*31*1.15mm BK7 or Quartz window.
Since the main application of the camera will be astrophotography, I tested how a Baader 26.5mm(diam)x2mm(thickness) UVIR block filter behaves if I tape it on the rear side of the lens. I tested on my unmodified D7k body to be able to compare sharpness/vignetting with and without the Baader filter.
So far I havent seen any significant image degradation with the 18-105 AFS, 2.8/105AFD micro and 2.8/14 samyang!

Found this thread while looking for information on the ir conversion. The added pictures are very helpful. The ifixit teardown guide is pretty sloppy. One of the screws that kept me from removing the front is hidden inside the battery compartement. Other than that the conversion went smoothly. It really is not that challenging if you stay calm, stay organized and don`t apply ridiculous forces on the band cables.
Cheers!

did you manage to get it focusing to infinity in the end? Removing the filter messed that up?
how does it work for normal photography?

To be honest i haven`t checked focus for normal lenses. I only used it with a telescope so far. Also my modification went further because i removed every glass that was in front of the sensor in order to remove the color filter. I doubt i can reach infinity focus with most of my normal lenses, but i can try to check it tomorrow.

Re: Infrared conversion of the nikon D5100 - DIY
thanks for your response!
You did the full mono mod? Nice.
Did you follow these instructions: http://kuulapaa.com/home/astrophotography/nikond5100mod.html
It looks ridiculously difficult to me.. very easy to destroy the sensor. How did you get the colours filters off?

Hello,
i tried to remove the mask on one sensor myself, but failed. Not the removal of the mask is the problem but the removal of the protection glass in front of the sensor (there`s another glass after the "hot mirror"). The protection glass is glued with epoxy into an aluminium frame. The only way to get it out is by heat shock treatment (soldering torch). At this stage i fried the sensor.
In the end i bought a mono D5100 sensor from Herra (the guy in the link) for the price of a used D5100. For detailed information either contact Herra or have a look at the following thread on SGL: https://stargazerslounge.com/topic/166334-debayering-a-dslrs-bayer-matrix/
best regards
PS: The CFA (and the microlenses) are removed with a plastic polish and e.g a leather "rubber". It`s easy to feel when the microlenses have come off, because the lenses make the surface rather rough.

Re: Infrared conversion of the nikon D5100 - DIY
thanks for your reply! It looks like a lot of people have destroyed their sensors with this mod. I guess I will see if I can get an already modified sensor like you did!

I know this is a really old thread but did you ever mod your d5100? If so, were you still able to achieve focus at infinity with regular lenses. I have a d5300 and want to ir mod it for astrophotography. I have telescopes I can use it with however I'd like to do some wide field imaging with my 55-200mm f/4-5.6 vr ii ed. I want to do the mod myself because of how unappealing the almost $300 conversion cost is at lifepixel, however i'd like to make sure I can still achieve focus at infinity.
