Infrared Optics

We supply the very best infrared optics for a diverse range of applications across Short-Wave (SWIR), Mid-Wave (MWIR), and Long-Wave (LWIR) spectra. Using diamond turning and other conventional fabrication techniques, along with tightly controlled processes we strive to deliver your components on time and on budget — and always meeting or exceeding your specifications. Our industry-leading fabrication, project documentation, and data deliverables ensure your success, no matter the application.

Hardin Optical produces infrared optical components for defense, medical and commercial applications. Our extensive list of successes includes optical hardware in both small and large volumes to meet the needs of our customers and deliver beyond their expectations.
