Gavish

What Gavish does

Gavish is a privately held sapphire optics manufacturer founded in 1995 and headquartered at Omer Industrial Park in Israel, with a US sales subsidiary (Gavish, Inc.) in Bedford, New Hampshire, and a representative presence in Taiwan. The company is vertically integrated across the full sapphire value chain — from crystal growth through fabrication, optical coating, metallization, metrology, and packaging — and grows synthetic sapphire (Al2O3) using three methods (EFG/Stephanov, Kyropulos, and HDSM) to cover a broader range of form factors, sizes (from <3mm to >370mm diameter), and material grades than single-method competitors.

Its product portfolio comprises five core lines: sapphire optical windows, coated and metallized optics (BBAR, UV filters, bandpass/cutoff coatings, solderable metallization), sapphire tubes and injectors for plasma and thermocouple protection, custom-fabricated sapphire components (precision ground, lapped, polished, drilled, threaded), and sapphire rods and lift/guide pins produced at tolerances to 0.0005 inches. The company operates a fully equipped metrology lab including Varian Cary 50 spectrophotometers, Zygo interferometers, and Keyence inspection systems, and holds ISO 9001:2015 certification in both Israel and the US as well as ITAR registration.

Gavish sells exclusively on a direct B2B basis to enterprise customers in semiconductor process equipment manufacturing (plasma chambers, vacuum chambers, lift pins, showerheads), medical equipment OEM (laser, imaging, SWIR optics), and university research institutions. Pricing is custom quote-based per specification, with no public pricing tiers and revenue generated through one-time component purchases rather than recurring licensing. The company does not disclose revenue, has no known outside investors, and operates with 11–50 employees — making it a small, founder-controlled, specialty industrial manufacturer.

Core offering

Gavish manufactures custom engineered sapphire (Al2O3) optical components, controlling the entire production chain from synthetic sapphire crystal growth through precision fabrication, optical coating, metallization, metrology, and certified packaging. Products include sapphire windows, coated/metallized optics, tubes, injectors, lift pins, rods, and custom-fabricated shapes engineered for semiconductor process equipment, medical laser/imaging systems, and research applications.

Product overview

Gavish is a sapphire optics manufacturer founded in 1995, operating as a vertically integrated company that grows sapphire using EFG/Stephanove, Kyropolus, and HDSM methods, then fabricates, coats, and metallizes it into precision optical components. The product portfolio consists of five core offerings: Sapphire Windows (optical windows for imaging, laser, and sensing applications), Coated & Metallized Optics (BBAR, filter, and solderable metallization coatings), Sapphire Tubes and Injectors (plasma and thermocouple protection components), Custom Fabricated Sapphire (precision-machined components with threaded, shaped, and complex geometries), and Sapphire Rods & Lift Pins (mechanical components for semiconductor processing). Supporting these products are Technical Data Resources providing material specifications. Gavish serves markets ranging from university researchers to major semiconductor and medical equipment OEMs.

Products and services

• Sapphire Windows Optical sapphire windows for flame detectors, vacuum chamber windows for semiconductor process chambers, laser windows, intense illumination, light guides, optical probes, and lenses/prisms. Available in diameters from less than 3mm to over 370mm with flatness less than Lambda/10. Targeted at semiconductor OEMs, medical equipment OEMs, and research customers.
• Coated & Metallized Optics Sapphire windows and arrays with solderable metallization and AR or filter coatings, including BBAR anti-reflective coatings, UV filters, bandpass/cutoff coatings, reflective coatings, and solderable metallization for hermetic sealing in vacuum applications. Designed for cameras, imaging, and sensing devices operating from visible through Short Wave Infrared (SWIR).
• Sapphire Tubes and Injectors Sapphire tubes, injectors, spray injector nozzles, and thermocouple protection sheaths for semiconductor process equipment and other high-temperature applications. Made from acid-insoluble material resistant to hydrofluoric acid and fluorine plasma, usable to 2000°C.
• Custom Fabricated Sapphire Precision grinding, lapping, polishing, shaping, drilling, and threading of sapphire into threaded components, complex geometries, thin-walled showerheads, integrated flanges, and polished faces/diameters for specialized customer applications.
• Sapphire Rods & Sapphire Lift Pins Sapphire lift pins, guide/alignment pins, and polished rods for semiconductor wafer handling and optical light guide/sensor probe applications. Provides high mechanical strength with diametric accuracy to 0.0005" and dimensional stability within 0.0002" (5 microns) in high-temperature plasma environments.
