Meller Optics

For more than 35 years, Meller Optics has been the original supplier of centrifuge cell windows to Beckman Coulter. Today, we continue that expertise with OEM-quality sapphire replacement windows for Beckman® and other high-speed centrifuges. Melleroptics.com

We specialize in the precision fabrication of custom optical components for OEMs, research institutions, and government contractors.

Our capabilities include sapphire windows and lenses, optical flats, prisms, domes, substrates, infrared optics, and custom optical components manufactured to exact customer specifications.

We provide precision CNC machining, grinding, polishing, edging, drilling, and optical metrology to ensure every component meets demanding performance requirements.

We work closely with engineers to solve challenging optical manufacturing problems, producing high-quality components with tight tolerances, rapid turnaround, and responsive customer service. Our ITAR registration, DFARS compliance, and commitment to American manufacturing make us a trusted partner for aerospace, defense, medical, scientific, industrial, and laser applications. Made in the USA.

Sapphire remains one of the most versatile optical materials available.
✔ Excellent scratch resistance
✔ High mechanical strength
✔ Outstanding thermal stability
✔ Broad optical transmission
That's why it's used in demanding industrial, defense, aerospace, and scientific applications. Melleroptics.com

Stronger than glass. Built for demanding environments.

Sapphire optics provide exceptional scratch resistance, thermal stability, and optical performance for applications where durability matters.

Optical clarity combined with mechanical strength — engineered to last.

We’ve seen repeated cases where optical components fail not because of poor design—but because the wrong material was selected for the environment.
Harsh conditions like abrasion, heat, and chemical exposure don’t expose design flaws as much as they expose material limitations.
In those situations, sapphire often becomes the clear choice for durability and long-term performance.

What's the most unusual way you've seen an optical component fail?

Scratched coatings?

Thermal shock?

Chemical attack?

Unexpected contamination?

Every engineer has at least one story.

We'll start: many industrial windows fail because the material wasn't selected for the actual operating environment.
