ARCADE: Blinkenlights with Tetris

BorrisYeltsin writes "The guys from blinkenlights are doing it again, but this time in France on a 26x20 display, for 11 nights at the "Bibliotheque nationale de France" in Paris. This time instead of pong you get to play tetris on this 520 pixel display. Again they need your animations for the project."

    Of course, there will always be a bit of color error due to
    sphero-chromatism, etc. in apo refractors. The very fact that the
    colors in an Apo come so very close to focus (and are not spread out
    into a thin imperceptible haze), allows you to see them as slight
    fringes on the out of focus patterns. It is ironic then, that when a
    lens has very poor color correction, you may not see or notice a lot
    more of this when defocusing the image. For instance, if the blue end
    of the spectrum goes out of focus ever so slowly with decreasing
    wavelength, there is a lot of energy in the slightly out of focus
    waves. If, on the other hand, the blue end goes out of focus very
    rapidly, the decreasing wavelengths are so far out of focus, that the
    energy is spread out very far away from the disc, and contributes
    very little to the fringing effect. Thus, an inexperienced tester
    could easily conclude that a lens with very poor color correction in
    the blue does not seem to have very much color error. The color error
    is indeed there, but being so far spread out, it seems to disappear
    into "thin air".

    In lenses, the key is the color of the in-focus disc. The whiter it
    appears at focus, the better is the correction. In a lens with lesser
    color correction, the in-focus disc will appear more and more
    yellowish (at reasonably high powers of course). The resolution is
    not necessarily any different, but the main effect is that with
    better color correction, there is more light concentrated in the
    image, and fainter stars can be seen. Globulars, for instance, should
    look more crisp and the individual stars in the globular should have
    more of that sugar sparkle look.

    One can indeed make a fast achromat that would appear to have "very
    little color", simply by bringing the red end of the spectrum closer
    to the yellow and green waves. This sacrifices the blue end. In other
    words, if you cut the red error in half in a normal achromat, the
    blue error will double. This is called Cde correction (red yel green)
    as opposed to the normal CeF (red green blue) correction. The old
    time achromat designers tried to include as much of the visible waves
    as possible with the CeF correction, and relying on long focal
    lengths to increase the depth of focus and reduce the perceived color
    error. If a 6" F8 were made that way, it would look colorful, indeed.
    By skewing the color curve toward the red, and sacrificing the blue
    end, the perceived fringe does not look any bigger (far out of focus
    blue and violet waves have very little energy per unit area). Since
    the red end is close to focus, you will not see the typical "purple
    fringe", which is not really violet light, but the combination of red
    and blue.

    At low power, these lenses do have an almost Apo look to them,
    especially on the Moon. With an object that bright, two things
    happen. Your eye's color perception shifts over to the red end of the
    spectrum, and because of the brightness entering your eye, your pupil
    contracts. In effect, your eye stops down the aperture. So, instead
    of seeing the Moon with a 6"f8, you may be stopping it down to 3 or 4
    inches due to pupil contraction. If you move your eye around the
    eyepiece, you may catch glimpses of the light originating from the
    outer part of the lens' aperture, and will see various amounts of
    violet and blue flaring in and out. On deep sky, the eye has no color
    response, and everything looks white, no matter how well or poor the
    color correction is. I would expect a 6" F8 achromat with Cde
    correction to show bright globular star clusters buried in a thin
    nebulous haze (the out of focus blue and violet light). The
    brightness of the haze would be less, the worse the color is, and
    would depend, of course, on the magnitude of the cluster. If this
    background haze is below the detection limit of the eye, you might
    not see any. It would be interesting to compare this nebular
    background in CCD images taken with this kind of lens vs a mirror
    scope, or high end Apo.

    To clarify the situation on color correction a bit more for those
    who'se eyelids have not already closed and are nodding away from all
    this technical mumbo-jumbo, I will attempt to explain where achros,
    EDs, fluorites etc fit into the scheme of things by comparing the
    ability of each design to produce a reasonably focused image spot
    diameter over its wavelength range. Reasonably focused being
    somewhere around 25 microns.

    Fast 6"F8 Cde achromat: 550 - 650 nm
    Long 6"F15 CeF achomat: 480 - 650 nm
    Fast 6"F9 ED doublet: 450 - 650 nm
    Fast 6" fluorite doublet: 420 - 1000 nm
    Fast 6" FPL52/53 triplet: 380 - 1000 nm
    Fast 6" fluorite triplet: 360 - 1000nm

    It would be interesting then to divide the cost of each lens by its
    useful wavelength range. For instance, a 6"F8 Cde achromat selling
    for around $800 today would come in at $10 per nanometer. (our 6"
    EDFS at $4900 comes in at $7.90 per nanometer). Interestingly, an 8"
    SCT selling for around $900 comes in at $3.81 per nanometer. No fair
    asking how a Newtonian would fare!

    Seriously, why would you need correction well into the blue-violet
    past 480nm? With black and white emulsions, this was necessary
    because they have considerable sensitivity down to 380nm. Today's new
    blue sensitive CCD cameras also need good correction in the violet.
    Also, CCD cameras pick up lots of IR light below 650nm, so correction
    to 1000nm is a distinct advantage. For pure visual use, it would be
    quite sufficient if the useable range extended only from 440 to 650
    nm. So, check the above table for your particular needs and make your
    choice.

  33. Should I worry about my fluorite telescope? by Anonymous Coward · · Score: 0

    Crystalline Flourite, and to a lesser extent ED glass, is sensitive to thermal shock, but only under certain circumstances. You could take a 6" disc of Fluorite (or ED) and drop it into boiling water, and it would be quite happy. Take it out of boiling water, and drop it into cold water, and it will shatter into a million pieces.

    A warm blank of Fluorite heated evenly throughout will crack instantly if a small amount of water is dropped on it. It does not have to be very warm. The amount of heat that water can absorb is quite large, and the sudden contraction of the material surface will cause the surface to erupt and crack. Once a crack has developed, it is only a matter of time before the glass splits into two pieces. This is also true of ED glasses, although they require more cooling shock. It is doubtful that simply exposing warm fluorite to cold air would result in any damage - in fact there is a 10" Fluorite refractor on top of Kitt Peak that has survived several winters without damage, but I think the Fluorite is in the back, protected by a cover element. What can cause the Fluorite to split is to take a warm element into a bitterly cold night and expose the surface to a high freezing wind. I would be very cautious to not let that happen. I have experienced a 4" fluorite blank splitting in half under just such conditions. Fortunately, most fluorite lenses are somewhat protected deep within their cells, and even the dewcap offers a lot of protection against sudden temperature shocks.

    As far as using canned air to blow off dust - I would be very careful. I once accidentally caused the surface of an ED element to erupt and crack open when the canned air accidentally spit out a stream of frozen material. The ED was rescued by immediately grinding 3 mm off the surface before the crack had a chance to propagate.

    ED glass can withstand high temperatures, but crystalline Fluorite will delaminate above a certain point. I found that out the hard way too. I don't know where that point is, but suspect it begins to happen above 250 degrees F. If the material partially delaminates, it will be very susceptible to moisture attack, and can cloud up eventually. Besides, it destroys the figure. I would not leave a Flourite refractor on the back seat of a black leather interior car on a hot sunny day. Perhaps once or twice is fine, but I would not do it repeatedly. In fact, I would not subject any scope to that treatment.

    Finally, a word about coatings. No!, Fluoride coatings are not the same as Fluorite optics. Magnesium Fluoride (Mag Fluoride) has nothing to do with color correction, and is in any event not used to coat Calcium Fluoride or Fluorite optical materials. The type of coatings normally applied to Fluorite are oxide multilayers, which can be applied without using extremely high temperatures, and they are tough and scratch resistent. They won't fall off if you blow compressed air at them.

    I hope this clears up some misconceptions about these materials.
