Manasota Optics, Inc. (MOI) is a “build to print” manufacturer of metal optical components that are used in the Defense and Aerospace Sector. MOI fabricates optics that are used in various sighting systems in military vehicles, laser rangefinders, targeting and infrared countermeasure systems, scanners, biological & chemical detection systems and space applications.

Diamond TruingManasota Optics' Diamond Turning Equipment consists of the following Custom-Built Single Point Diamond Turning “SPDT" "Fly-Cutting" Machines. Diamond Turning materials consists of variety of Bare Aluminum 6061, 5052 and 7075, Electroless Nickel Plated Substrates, Copper, and Invar. MOI's Diamond Turning produces "plano" or flat optics.

The sizes of components can range up to 15" in length and the optical requirements are typically 1/8 wave PV or better depending on the part geometry or aspect ratios and 40-80 angstroms RMS for surface roughness.

MOI's Diamond Turning Machines can meet tight angular requirements for Polygons or scanner optics.

The Diamond Turning Machine Controllers have been upgraded to allow for quick repairs and expansion slots were added for future upgrades.


Bare Aluminum, Copper, Silver, Invar, and Brass as well as Nickel Plated Aluminum

  • Plano (Flat) Optics up to 15” in length.
  • 1/8 Wave PV, 40-80 Angstroms RMS
  • Ability to hold tight angular tolerances

Optics Polishing and GrindingManasota Optic's Polishing/Grinding Department can produce "plano" or flat optics as well as spherical components. The sizes of components can range up to 24" in diameter and the optical requirements are typically 1/8 wave or better PV and 20-40 angstroms RMS for surface roughness.

The planetary polisher has a lap surface which accommodates three 26” polishing rings, allowing us to polish three 24” mirrors at one time.  MOI also has tooling capabilities to produce many smaller components within the 26" ring. The flatness of the lap is controlled by a 40” conditioning granite rock, which results in controlled material removal and near identical flatness of the mirrors in the polishing rings.

The single and dual spindle machines give MOI the autonomy to run many different components simultaneously that have different sizes, shapes and or optical requirements.

MOI's Polishing Equipment consists of the following:

  • 72" Strasbaugh Planetary Polisher
  • 9 Single Spindle Polishing / Lapping Machines
  • 1 Dual Spindle Polishing / Lapping Machine

Polishing and Grinding materials consists of Electroless Nickel Plated Substrates, Copper, a variety of Stainless Steels, AlBeMet and Titanium.
