PARABOLIZATION After bringing the mirror to the sphere, the moment of parabolization has arrived, which for many is perhaps the most delicate phase of the entire process. In this specific case, a machine configuration was adopted designed to preserve the edge of the mirror as much as possible, which in the initial spherical surface was already clean and
OVERVIEW OF ALL WORKING SESSIONS The mirror processing was carried out with a mirror-o-matic type machine, characterized by a rotating table and an oscillating arm on which the tool is fixed. The latter can be positioned at different points along the arm, allowing you to vary the offset with respect to the center of the mirror e
INITIAL PHASES AND CONTROL OF VOLTAGES INTERNAL TO THE BLANK In these chapters I will describe the phases that led me to the creation of a parabolic mirror to 410 mm f/4.5, focusing first on the phases that led me to create a good spherical surface, necessary for the subsequent parabolization phase. Let's start with the preliminary checks that are
The manufacturing phases of a meniscus parabolic mirror 610 mm in diameter and 20 mm thick, focus 1770 mm with focal ratio of F3.

Building a Ritchey-Chretien: preconditions
And, it's possible to do it (*) by manually working the optics and you don't need special equipment or more sophisticated than what we normally use for the construction of a parabolic mirror but, let us now, to embark on such an adventure necessarily have to have more than one working behind, to understand how to generate two hyperbolic surfaces, and
