Front Surface Mirror - What is it? [Optical Mirror Academy] (2018)
Front surface mirror (first surface mirror) is an optical mirror which reflects an distorted image off the surface, eliminating a double image (also known as ghosting).
To make a high quality first surface mirror, aluminum is deposited on glass that's been carefully selected for flatness and screened for defects. A dielectric overcoat is applied to prevent the aluminum from tarnishing, and adds substantial durability.
Front surface mirrors are used in science and engineering projects, projector bounce mirrors, barcode scanners, binocular mounts, and for product photography.

Casting a $20 Million Mirror for the World’s Largest Telescope
Building a mirror for any giant telescope is no simple feat. The sheer size of the glass, the nanometer precision of its curves, its carefully calculated optics, and the adaptive software required to run it make this a task of herculean proportions. But the recent castings of the 15-metric ton, off-axis mirrors for the Giant Magellan Telescope forced engineers to push the design and manufacturing process beyond all previous limits.
How To Make Solar Concentrating Mirrors (super HOT focal point)
In this video I show how to convert inexpensive truck mirrors into powerful first surface solar concentrators. Check out my sponsor Brilliant for a really fun way to learn!
First surface mirrors are an extremely efficient way of concentrating solar energy, much more efficient for their size than a fresnel lens. This type of mirror is also essential for optical applications.

Pinched optics and how to correct it
A common aberration that’s misunderstood is a pinched optic. It’s common to have a factory telescope pinched right out of the box. Not much information is provided regarding the correct way to secure mirror clips or lens retaining rings and so this may be an issue for a lot of people. This video takes a quick look at what pinched optics look like and a simple solution to correct it for Newtonians and refractor telescopes. I hope if you found this video that it helped you solve an often misunderstood problem. Clear skies.

Optical Mirror - First Surface Mirror for Science & Engineering
A first surface mirror, also known as a front surface mirror, is an optical grade mirror which provides superior accuracy for engineering and scientific applications. Unlike a standard mirror, which is coated on the second surface of the glass, a first surface mirror provides a true reflection with no double image.

First ELT main mirror segments successfully cast
The first hexagonal segments for the main mirror of ESO’s Extremely Large Telescope (ELT) are shown being successfully cast by the German company SCHOTT at their facility in Mainz. These segments will form parts of the ELT’s 39-metre main mirror, which will have 798 segments in total when completed. The ELT will be the largest optical telescope in the world when it sees first light in 2024.

Humans are running a dangerous experiment on our planet. We're putting more and more carbon dioxide and other gases into the atmosphere, which are trapping the sun's energy, and lo and behold, our planet is heating up in response.
To fix this, we could cut carbon dioxide emissions, but that’s been hard. What if there were a shortcut? What if we could reflect some of the sun’s energy away before it had a chance to get trapped? Like… maybe with space mirrors?!

Meade Instruments- f/8 & f/10 OTAs (Optical Tube Assemblies)
Meade's advanced ACf.
Equipped with Advanced Coma-Free (ACF) optics. A proprietary coma-free optical design delivers the ultimate in clarity, contrast, and with flatter fields of view.
All Meade ACF optics include over-sized primary mirrors.
The f/8 OTAs are available in 10, 12, 14 & 16 apertures. Includes dual-speed mechanical focuser, Losmandy-style mounting rail, and an internal Crayford-style focuser design for zero-image shift focusing. The 14 and 16 include a primary mirror lock to aid in long expsoure astrophotography. Wider fields of view and short exposure time when compared to f/10 optics.
The f/10 OTAs are available in 8, 10, 12, 14 & 16 apertures. Feature single speed mechanical focuser, Losmandy-style mounting rail, primary mirror lock, and higher focal length that yield increase magnification, ideal for planetary and deep-sky objects.
Track mirror projection
The track mirror, also called Magic Mirror, is a creative moving image that is reflected by a rotatable optical plane mirror. Provides a more flexible multimedia imagery presentation for the light dance design team.
Having an orbital mirror system enabling the image be adjusted and projected at any time on the stage or in the theater with live performances, multimedia videos, and light to interpret dynamic image effects.
The combination of creative film source and mobile creative imagery bring you a fresh and new sensory experience. The projection will be more vivid with 3 dimensional to show you with artistic effects.
Installing a HyperStar Conversion Kit
This kit allows a non-HyperStar-compatible SCT to be converted into a compatible telescope. The kit includes three components that replace the original secondary mirror assembly.
To install, the original assembly must be removed from the telescope. The corrector plate is removed first. Then the baffle tube is unthreaded to allow the secondary holder to be removed. The secondary mirror itself is then removed and placed into the new holder. This assembly is then put back onto the corrector plate and reinstalled into the telescope.
After installation, the telescope optics must be collimated, but collimation is then retained when the secondary is removed for HyperStar imaging. Removing the secondary mirror is done using a threaded ring. While out of the telescope, the secondary is safely stored in a holder included with the HyperStar lens.
Note: The old orange-tube Celestron SCTs have secondary mirrors which are mounted differently from the current model telescopes. This requires a modification to the Conversion Kit which is an extra $50. Please call to order the Conversion Kit or if you have any questions on which version your telescope requires.
