Conversion of an Olympus E-410 to an IR-Camera

After the conversion of an E-1 of mine to an IR-Camera ( suppoorted by this very fine documentation :
http://forum.fourthirdsphoto.com/showthread.php?t=29059 by Jens Birch), the idea suggested itself,<o></o>
trying the same with an E-system-Camera with ‘liveview’ ..The idea was that the AF<o></o>
was no longer responsible and the sensor assumes the problem of the sharpness<o></o>
(but don’t run away with this idea … for it is not a compact-camera ... and there is
still a problem - I've solved for myself) .<o></o>

The most important reason is, you can see the picture in the infrared colours <o></o>
before taking the picture.<o></o>

Caution !!! :<o></o>

By trying this conversion, the warranty of the producer expires .Therefore certain steps <o></o>
of this thread aren’t discribed .I don’t take any liability for the accuracy,completeness <o></o>
and the consequences of trying the following conversion .You will try it on your own risk !!!!<o></o>

First I had to unscrew the rear panel( Abb.), all about 9.

In this process 2 screws are hidden under the protection of the view finder. ( only the upper 2 are important ).

By lifting of the rear panel you have to be careful cause of a trace pitch inside , which connects the
display and the interior of the cam . This must not be unfixed – you simply can flip the rear panel up .
(For better sight I’ve removed it )

For the next step 4 screws have to be removed : 3 to fix the sensor , one (a) to hold the <o></o>
board - left aside the sensor .<o></o>
I only raised the board und pulled out the complete sensor … but<o></o>

CAUTION :<o></o>
By touching the frame of the sensor and the board it can cause an electric shock ! ! !

Now I lifted off the mount of the dust buster and then folded itself backwards . For I couldn’t get the
very damageable glas off – I had to be careful for not scratching the surface …

Next step : I’ve changed the filters ( the blue one is the combined Anti Alias with the IR-blocking filter –
the red one is an Schottglas IR 695 nm ) .That's the biggest problem !!! Replacing the metallic retaining
frame is a very difficult process. To get it back at its place was harder than all !<o></o>
<!--[if !supportEmptyParas]--> <!--[endif]--><o></o>
And now it’s time to get all together now …<o></o>
For nothing has to remain !<o></o>

With best regards,<o></o>

Very nice, this will definitely get moved to the keepers section at some point. Thanks!

Kobold,

Thanks for the tutorial. Where did you get the IR pass filter? Did you have to cut it yourself? Can a 720nm filter be used instead of the 695nm? How thick does the filter need to be? How much does the filter cost? I have an E-410 that I would like to convert, and wouldn't mind trying the conversion myself. Would like to have the filter in hand before taking apart the camera. Any info is appreciated.

on the same level, Im thinking AA less, where there has also been interest developing in this elsewhere.

Given (depending on your shooting regime) moire is likely to be present in <5% of your images, yet the AA filter dampens resolution 100% of the time, it just might not be as unreasonable as all that...
