Expect high quality optics (0.10m to 0.81m) using Computerized Polishing providing the best price/performance optics possible.
Instead of polishing to a specification and hoping for the best (as all mass produced telescope makers do), our opticians use interferometry to test and evaluate the wave front quality of each optical set made for RCOS. Integrating interferometry into their computerized polishing machines allows for fewer iterations which results in lower cost.
The result is a known quality with supporting documentation. View an Interferogram of a Computer Polished 20RC.
