Outstanding spectral measurements of optical coatings

We develop high-precision optical instruments to measure transmittance and reflectance on virtually any type of optical sample you can imagine

What makes us different

We have our own production technology well down to the key components - spectrometers and monochromators. As a result, we can easily adapt our solutions to the individual requirements of our customers allowing us to be more flexible in implementing responsible projects.

Our  instruments combine original technical and optical solutions, high meassurement accuracy and long-term reliable operation, providing our customers with a real competitive advantage.  

Who We Are

EssentOptics develops and manufactures optical instruments based on originally designed spectrometers and monochromators. All our products are specifically designed to meet the needs of optical coating experts.   

Process Control

IRIS and AKRA optical monitoring systems offer reliable process control ensuring deposition of optical coatings in the UV, VIS and IR ranges. The AKRA systems cover the widest spectrum range available now on the market. The IRIS broadband systems support our customers for trustful and high process yeild deposition even for high-spec coatings Read more

Measurement of plano optics

PHOTON RT UV-VIS-MWIR Universal Spectrophotometer is the only instrument on the market designed for unattended measurement of optical samples with coatings from 185 nm up to 5200 nm. Unique set of capabilities like absolute specular reflectance, transmittance and polarization-dependent measurements are provided as standard Read more

Testing of lenses

LINZA 150 spectrophotometer offers unique opportunity for unattended measurement of transmittance and reflectance on lenses and lens assemblies Read more

Thin Film Calculation

MultiSpectrum thin film software is designed for calculation of the intermediate target layers and supports our optical monitoring systems for reliable control of the vacuum deposition process Read more
