All advanced composite work is done in-house. The
image to the right shows three 20" OD hybrid profile tubes
designed for ~16"/40cm optical systems. The tubes
shown have two flat sides, for mounting, which eliminates the
need, additional flexure and mass associated with mounting rings.
Two tubes are 57" long and the other is 65.5" long.
The 57" long tubes are used for telescopes like the Dream 16" f3.75 Astrograph.
All three use Carbon Fiber skinned Sandwich
Core (CFSC), with a wall thickness
of ~1.0". This is what Dream has specialized in since its
inception in 2003; meticulous carbon fiber work for the much
more demanding opto-mechanical industry, especially the use of
thick sandwich core, for the ultimate in high stiffness and low
Held in the foreground is a 16.5" (physical OD)
mirror support that is made from carbon fiber and CFSC. Axial
and lateral supports act independantly, which prevents an over-constrained
condition (distortion of the optical figure). Lateral supports
hold the optic at its CG (Center of Gravity).
If you are frustrated by conventional tube flexure,
request Dream's thick-walled CFSC
tubes, mirror supports or complete telescopes. High modulus,
low CTE structures and sub structures help maintain optical alignment,
optical spacing and support optics with far lower displacement
(distortion). All of these combine to provide the ultimate in
The carbon fiber mirror supports and structures that
Dream produces in-house have more than a decade of empirical
testing behind them. As well as additional in-house expertise
