Optical Parts

Our capabilities include all aspects of rough fabrication—ie surface grinding, slicing, dicing, edging, lapping, and fine grinding to very demanding tolerances.
Our polishing capabilities encompass the fabrication of windows, mirrors, prisms, and retardation waveplates with the ability to routinely achieve surface quality of 10/5 scratch/dig with /10 flatness. Our surface roughness typically measures in the area of 3 to 5 angstroms RMS.
Tower fabricates most of your typical visible optical glasses like NBK7, Crystal Quartz, and Fused Silica but also has experience processing calcium fluoride (CaF2), magnesium fluoride (MgF2), sapphire, undoped YAG, and zerodur.
We can also provide coated optical parts that require:
• Anti-Reflective coatings to maximize transmission
• Reflective mirror coatings of Aluminum, Silver, and Gold (protected & enhanced)
• Partial reflectance beamsplitter coatings
• High Laser Damage Thresholds
