Optics Manufacturing

Assembly - Testing - Diamond Turning - Polishing - Tolerances

Navitar manufactures high quality optical lenses and components including high magnification imaging lenses, ultra-precision microscope objectives, 4K projection lenses, cine prime lenses and infrared (IR) solutions. We utilize conventional optics, diamond turned components, precision mechanics and world class assembly to deliver full OEM lens modules that meet demanding image quality requirements.. We produce large volume commercial orders and complex, custom-built prototypes - to exact customer specifications.

With our recent acquisition of AMF Optics, an ITAR registered and ISO 9000 certified facility, we now offer our customers precision single point diamond-turning and metal polishing capabilities.
