... Main mirror assembly consists of: . mirror cell structure . ... relief mechanisms . ... central bed Main mirror is fixed in the mirror cell in axial direction by three rigid supports. ... The butt relief of main mirror is implemented according to Lassel and involves 18 relief mechanisms, three of which are replaced by rigid fixing supports after the adjustment. The side relief is similar with the relief mechanisms working in both directions since mounting points are glued to the mirror. ...
... Bad Astronomy . ... Mad Science . ... The color of light is determined by the wavelength: the long wavelengths make red light, somewhat shorter makes yellow, shorter even than that makes blue. ... The red light gets reflected by the shirt and into your eye. ... A perfect mirror does actually reflect all light hitting it. ... A mirror, on the other hand, reflects the blue and red light in the same direction, and so the mirror actually builds an image of the source of the light. ... 2008 Phil Plait. ...

In 1995, Hughes Danbury Optical Systems (now Goodrich Optical and Space Systems Division, Electro-Optical Systems) donated to Winer a 2/3-m (26.5-inch) Corning Ultra Low Expansion ULE lightweighted mirror. Using this donation as a basis, we entered into a project with a private, non-sectarian school to design and build a telescope for the school and one for us. ...
The picture above was made with this demo POV file and this Mirror object POV file . ... This is a magnifying mirror with a light around it, on an articulated arm, designed for wall-mounting. ... Behind this mirror in the image are two more mirrors, one above showing the front, and one below showing the arm in a bent position, and the whole thing roated so that you are effectively looking "up" at it. ... The two images below show details of the base, and the back of the mirror. ...

... The very demanding goal of 50 milliarcseconds root-mean-square (mas RMS) for the astrometric precision of the Sloan Digital Sky Survey implies that focus and collimation motions of the secondary must be very smooth. The Apache Point Observatory 3.5-m telescope secondary is a hot-gas-fusion borosilicate lightweight (25% of solid) mirror. ... Differential rotation provides tilt motions. ... Also, we made measurements with the indicators sensing the motion of the whiffletrees near actuators 1 and 2. ...
Circling around magnetic field lines. ... The ring current . Because positive ions and negative electrons drift in opposite directions (see drawing), that motion will create an electric current that circulates clockwise around the Earth when viewed from north. ... How then can the radiation belt and ring current arise? ... Electric fields are able to push trapped particles earthward, and unlike the purely magnetic motion described earlier, an electric field can also energize them. ...
... I am interested in Fano varieties -- those whose some multiple of sheaf of higher holomorphic differentials embeds them to a pro jective space. Mirror conjectures state an existence of a so called dual LandauGinzburg model, that is an open smooth CalabiYau variety with non-trivial complex-valued function called potential. ... The pro ject has 3 main directions. ... Mirror Symmetry predicts duality between anticanonical sections of Fano variety and fibers of its dual LandauGinzburg model. ...

The first near-infrared IFU spectrograph was the 3D instrument , constructed by the Max Planck Institut f r Extraterrestrische Physik. ... An effective slit width of 0.1" was chosen in order to probe to spatial scales approaching the 0.07" diffraction-limited image core size expected from the Gemini adaptive optics system at 2.2 microns while maintaining an acceptable field-of-view. ... The field mirror array then feeds the spectrograph collimator mirror (seen at left in the above figure). ...
