Those are seriously good fotos! I do like that last one of the IC- that could almost have been taken through a microscope! The one of the frazzled bulb is good too- the melted ends of the tungsten filament can be very clearly seen. What sort of bulb is that?<HR></BLOCKQUOTE>
That was the bulb that blew up inside my ProMetric system's calibrator a couple of days after I got it. It is (or was) a 575 watt quartz iodine.

In the past, I have improvised means to take macro pictures. Here`s a few of my attempts, using a modified CCTV camera.<HR></BLOCKQUOTE>
I've seen the one of your diamond shaped LED die before. Sure is a strange critter.
You sent me one of those too last spring, didn't you? I'll have to dig through all of my little stashboxes to see where I put it so I can try to photograph it myself.

That's comparable to what I could do with my old camera, and it ain't too bad for a CCTV.
I have a couple of TIP-chip Luxeons around here that I should try to photograph.

These all took ages to get right, mainly cos the camera has to be so close to the objects that they almost touch the lens! Lighting these is [extremely tricky
<HR></BLOCKQUOTE>
Tripod helps. For lighting I balanced a Photon Fusion headlamp somewhere near the su bject where the camera wouldn't bump it.
It still isn't enough for those really close shots though, because the focal length can be measured in millimeters so the lens places the subject in shadow no matter what.
Manually holding the lens in place on the face of the camera introduces problems of its own, namely, movement. Once I find a way to secure the add-on lens while still allowing it to automatically fall off should the camera suddenly power down and retract its own lens, I can take these pictures totally hands free, using the self-timer. No more movement, which is of utmost importance with high magnifications like this.
P.S.
Your little axial lead bulb looks burnt out. :0
