See the Difference

From Conventional Cavities to Open Cavities

See how E-VITY's open-cavity designs address light leakage and integration limitations while expanding optical-cavity applications.

Conventional Cavities

Light divergence, surface imperfections and misalignment can lead to low stability and significant light leakage.

E-VITY Open Cavities

Open-cavity designs feature Direct Injection Stability and Real Ray Stability, enabling low-cost integration and tolerance to environmental variations.

Higher Reflectivity

In conventional cavities, light leakage limits the benefit of higher reflectivity; E-VITY's optical cavities show significant efficiency gains as reflectivity increases.

Expanded Applications

Applications extend from precision optics to UVC air purification, photocatalysis, cavity-enhanced spectroscopy and sensing.
