Powers of 10

    Since my fluorescent source it at the shop for repairs, I took the opportunity to set up a proper macro imaging setup. I saw the "Powers of 10" movie in school, maybe 1st or 2nd grade, and it had a lasting impact on my career choices as a scientist. So, I decided to take a series of images similar in spirit to the movie as an homage to the filmakers, and (possibly) as a warm up to 10/10/10:

    http://www.powersof10.com/

    The first series of images is of a filter insert from an old Leitz microscope, and the second is of a 0.055" diameter bolt. The height of the 'K' is 0.07" in the first series. All images except for the final one in each sequence are full-frame.

    The lenses used for the first set are (in order): 24mm macro, 85mm planar, 100 mm luminar- two, 63 mm luminar- two, 25 mm luminar, 16 mm luminar, and a 100% crop of the 16 mm luminar. I estimate the range of magnification from the first to the last is about 1:10^5.

    The lenses used for the second set are the same as the first, but I've added the zoom luminar (one) in between the 85mm and 100 mm, only used one magnification at 63 mm, and then added a 16x, 40x, and 80x epiplan microscope at the bottom end. Again, the final image is a 100% crop at 80x, and this sequence represents a magnification range of about 1:10^6.

    As I said, these are warm-ups for something a little more 'professional', once I find something good to photograph- maybe a fine patterned cloth or needlepoint, for example.

    Enjoy!

    Very nice! But why does the ninth photo of the second lot seem different?

    Good eye- when I switched over to the epiplan objectives, the working distance got so short (<< 1 mm) that I needed to move the light. Consequently, I've adapted the luminar epi-illuminator for the next sequences of images (forthcoming).

    That is very cool.
    I will tune in for your subsequent demos.

    thanks- I made some progress last week (popped the top off a DSP with excellent results), but I'm still working on imaging dielectric materials (wood, paper, etc)- epi illumination provides nearly zero contrast.

    Hopefully I'll have something worth posting in a couple of weeks.

    Ok- here's my (likely) final two series. These images took a long time to setup and arrange, but I'm very pleased with the outcome. There may be a Nikon Small World submission hiding in these. These will be a part of a seminar I'm presenting here at CSU, and (shameless self-promotion) I'm willing to travel.

    The first set are images of a computer chip. Boring and cliche', I know. However, the images show the effect of lighting: most of the macro images use oblique reflected illumination, while the micro images use epi-illumination and DIC.

    The second set of images is of the balance point on an old analytical microbalance that I got from my dad. I really like these. All were done using reflected oblique illumination. For some reason, epi-illumination completely obliterates all contrast in dielectric materials: I tried stamps, 1200 grit sandpaper, and a wooden box. The 'box' images are ok, but in the interest of space I won't post them here.

    None of these images have been altered (other than size). Again, all full-frame except for the last computer ship image.

    Something about the luminars I really like is the level of contrast the images have: deep blacks and bright whites can coexist right next to each other (acutance).

    Enjoy!

    I don't have one. Too lazy/insufficient motivation. Although now that I have a lab and stuff to populate a site with, I should at least go and get a domain name.

    DaveC426913 gave me sufficient motivation- I started a blog for my lab. I won't duplicate postings, most likely I'll put a single image here and have the extended images/discussion on the blog.

    New set- an errant bluetooth headset fell into my clutches, and I couldn't resist taking it apart. It's takes time to find objects that look interesting through this large magnification range; computer chips and biological materials are pretty much the only things I have found. The headset has a a couple LEDs, one of which I assume is GaN, which has a nice blue color against the reddish copper tracings.

    Enjoy!

    Blimey, metal equipment and is that metal trunking I see running around the edge with a power supply on. Would I be right in thinking you don't have an earth on your equipment over there (I'm assuming you're in the states with the two pin plug)?

    Bit risky ain't it. :eek:

    Yes, after looking through all of those lovely pics, that is what I pick up on and feel urged to comment about!

    Hm? Let's see- the electrical lines are three-conductor (hot,neutral, ground); the white box is a lamp housing (which has a power supply inside, but I don't think that's what you meant), but yes- I do have a lot of electrical, optical, biological, and chemical hazards in my lab. Part of lab training for scientists is learning how to mitigate and control hazards.

    Sure, accidents happen- a chem. prof. here electrocuted himself last year (and the university is not at fault).

    Ah, so you do have an Earth in your electrics. Didn't think you did. Problem solved.

    In the UK, you're not supposed to fit any metal electrical fittings without an earth (ground). If it was to short to the metal and you touched it, you'd be in for a nasty shock.

    You can have all the lab training in the world, but if you don't have an earth and it shorts to a metal case / trunking / machine, you're going to be in a world of pain.

    Are you taking requests? =P If so:

    1) something biological/organic.
    2) something "fractal"

    Of course- at least, I can do my best. I have some fish vertebrae that may be interesting, and some sort of highly porous rock (maybe a byproduct of the local steelmills). Since the semester is almost over, I'll have some time to play.

    When it rains, it pours: here's another interesting object. This will be the last series for a little while, I found something that should give me some amazing images or be a complete failure- it's going to take a while for me to grok the thing.

    A long time ago, when the Earth was much younger, people recorded sounds on plastic disks called 'records'. These were large and prone to damage. After the usual sequence with the Luminars (which gave *amazing* images), I put the thing under the Ultraphot for further enlargement- up to 160x. I'm not sure where the colors came from, but they add a nice abstract quality to the images- I took images both of the top surface, and the bottom groove. One can almost hear Jello....

    Enjoy!
