Astro Optics has the capability to process spherical and plano surfaces.
We have complete in-house facilities right from slitting to thin film coating.
We use conventional slow speed pitch polishing machines from Dama, LOH, Rogers & Clark for precision requirementss as well as Korean diamond lapping and pad polishing machines for faster production.
We have Laser aided centering & Edging machine from LOH.
Our coating machines from Leybold are located in Class 10,000 cleanroom. Both are equipped with electron beam evaporators for multi-layer dielectric AR and beamsplitter coatings as well as thermal evaporators for metal coatings.
We also have metal working machinery including a CNC turning machine from Hardinge, USA.
We have a number of skilled empoloyees with more than 25 years experience in precision optics.
