EssentOptics at Photonics West 2026

At EssentOptics, we work with optical metrology challenges that go far beyond individual measurements or instruments.
Our strength lies in the ability to support real optical applications — across geometries, spectral ranges, and performance limits — with consistent accuracy and physics-based measurements.

From deep ultraviolet (185 nm) to long-wave infrared (14 µm),
from classical thin-film coatings to ultra-steep edges, ultra-narrow bandwidths, and extreme optical densities,
from planar optics to diffraction gratings, prisms, and complex optical components —
EssentOptics solutions are designed to address the full spectrum of modern optical challenges.

This application-driven approach allows us to act not only as an instrument provider, but as a competent technical adviser and long-term partner, supporting optical development, verification, and production over many years.

At Photonics West 2026, we look forward to discussions focused on:

• DUV coating measurements with polarization and variable angles of incidence
• characterization of ultra-narrow bandwidth filters and steep spectral edges
• reference-free, absolute measurements in the LWIR range
• spectral efficiency and polarization analysis of diffraction gratings

Explore how these challenges are addressed across different application domains:
