Dream
Hypergraph - Prime Focus Telescope: 32" f3.0 |
|
* The telescope is optimized to provide 100% illumination
of a 60mm diameter focal plane. But it can be used with even
larger focal planes, with vignetting. A custom version can be
produced for greater illumination of fields up to 135mm in diameter. |
|
* The 100%
illuminated field provides a 1 square
degree field. |
|
* Like all Dream telescopes, carbon fiber and
carbon fiber skinned sandwich
core are used extensively, including
the main telescope structure, primary mirror mount, backplate
and the main housing & internal spacers for the 4-element
Prime Focus Corrector (PFC) that comes with this telescope. |
|
* Primary mirror is an engineered, lightweight
Dream mirror. |
|
* Due to Dream's well-matched, in-house fabricated
carbon fiber and mirror technologies, the telescope is extremely
stable through temperature changes. |
|
* It includes
ASCOM-compliant focusing. |
|
* The telescope includes Dream's Filtered Air
System Technology, which means it has the lowest maintenance
of any product on the market. |

32" PM obscuration: PFT versus Newtonian
configuration. |
|
|
|
|
|
This Prime Focus Telescope(PFT), no Secondary Mirror (SM), offers higher
throughput and performance compared to a fast Cassegrain or Newtonian
configuration (Nc) for numerous reasons; |
|
* Reduced
obscuration means less diffraction effects and the use of more
surface area of the Primary Mirror (PM). Obscuration: <205mm
for PF versus 475mm for Nc. See the animation above showing that
94% of the PM is used in the PFT, while only 66% is used in the
Nc. |
|
* No light loss from SM surface. |
|
* No quality loss from SM surface. |
|
* Optical alignment is simplified. |
|
* Baffling is both simplified and can be
more complete. |
|
* Symmetric optical system provides better mechanical performance,
which leads to better all-sky performance. |
|
* Future re-coating only involves one mirror,
not two. |
|
* Installation & alignment far
more straight-forward for PFT. |
|
|
|
This telescope is ideal for a wide
range of discovery, follow-up, research and other applications:
NEO, LEO, KBO, GRB, SN, comet, survey and wide field imaging.
The telescope offers unprecedented all-sky performance, throughput
and field size. |
|
|
100% illumination of 60mm focal plane diameter, with
optical design spot performance that is optimized for seeing
as good as 0.5 arc-second.
It is currently optimized for 400-750nm waveband but
can be customized. Contact Dream to discuss your needs.
Dream has a great many designs to draw from for faster
opto-mechanical systems. From fast Cassegrains to fast Newtonian
& Hypergraphs to folded & straight PFT's. Contact
Dream to discuss your needs. |
