|
* Optical & mechanical research and development
for Classical and Ritchey-Chretien Cassegrains at: f8, f10 and
f12. |
|
- f12 Dall-Kirkham versus CC
versus RC |
- f8 Newtonian versus CC versus
RC |
|
- A 20" f8 Ritchey-Chretien Cassegrain OTA has been spec'd
out. |
|
- Optical specifications can be viewed at the bottom of this
page. |
- The OTA is an open truss, estimated at 56.5" in length.
Total weight, with focuser and optics, is estimated to be 75
lbs, with conventional glass technology. Cellular optics would
allow for a 55 lb 20", which includes electronic focuser,
thermal control system (temperature probes and cooling fans),
mounting plates, etc.. |

* Completed rapid CAD prototyping for
a customer's kick-off meeting with the US Navy. Meeting occured
one week after Dream was initially contacted by this customer. |
|
|
- OTA and mounting rings for an 8" four element refractor,
f4.3 |
- Due to the weight of this lens and cell, the OTA needed to
be stronger and more rigid than a typical OTA in this size |
- Imaging at 1.6 microns (1600nm), infrared - visual is 400-700nm |
- Design needed to be fully baffled and completely light (IR)
tight |
- Reduced CTE was important to hold focus better than metal alternatives |
- Customer will provide lens in cell and CCD camera |
- CAD work was completed two days before clients meeting and
four days after initial contact |
* Dream has been contracted to provide a prototype spherical
mirror for the initial prototype/testing phase. The four element
refractor has been changed to a combination refractive and reflective
system for numerous reasons. Eventual product, which will include
three optical assemblies housed within one composite structure,
will begin fabrication around September of 2004. |
7/1/04 - Dream has delivered the prototype mirror on time. Optical
test documentation was included. Documentation was also provided
for the reflectance percentage at the planned 1.6 micron wavelength. |
11/04 - Client is completing initial testing of prototype design,
that utilizes the spherical primary mirror Dream delivered. Lockheed
has shown interest, to Dream's client, in the project as well. |

|
* Initial design work for a University portable
~1m complete telescope. |
- determine trailer size, opening design and mechanisms, etc. |
- fork or split-ring type telescope mount |
- weight of complete telescope, without trailer, should be less
than 500lbs |
* Dream was hired to do the initial
design work for a unique roll off structure to house the 38"
telescope. The telescope design is now a low-profile Dobsonian
to be made of welded steel, produced by another vendor, not Dream.
The unique enclosure
will be approximately 20 feet by 30 feet. A control room
will be housed at one end of the structure. |
|
|
- Initial design phase is complete.
Second, more detailed, design phase will soon begin. |
|
|
- This project was cancelled due
to the optician going out of business. |
