21.06 Laser World of Photoncs 2017: EssentOptics will showcase its PHOTON RT spectrophotometer - the only instrument developed exclusively to test optical coatings

10.04 EssentOptics will demonstrate its optical testing technologies during the OCLA 2107 Symposium.

16.01 EssentOptics has prepared its trend-setting PHOTON RT scanning spectrophotometer for display at coming PhotonicsWest 2017 show (German Pavilion, booth #4629. January 31 – February 2, 2017, Moscone Center, San Francisco, CA).



About us

EssentOptics develops and manufactures optical instruments based on originally designed spectrometers and monochromators. All our products are specifically designed to meet present and future needs of optical industry experts. Our product lines include:


  • PHOTON RT UV-VIS-MWIR Universal Spectrophotometers are the only instruments on the market developed specifically for unattended measurement of optical samples with coatings from 185 nm up to 5200 nm, including absolute specular reflectance, transmittance and polarization-dependent measurements in wide angular and wavelength ranges
  • LINZA 150 spectrophotometers offer unique opportunities for unattended measurement of transmittance and reflectance on lenses and lens objectives
  • IRIS Broadband spectral optical monitoring systems and AKRA monochromator-based optical monitoring systems are developed for reliable monitoring of the vacuum deposition of optical coatings in the UV, VIS and IR ranges up to 20 um. The AKRA single wavelength optical monitoring systems cover the widest spectrum range available now on the market. The IRIS broadband monitoring systems ensure trustful and high process yeild deposition even for multispectral coatings.
  • Specialized software for IRIS and AKRA systems, as well as MultiSpectrum thin film calculation software.

We develop and possess our own technology down to spectrometer and monochromator levels. Having our technology "in-house" means we own the production process and can adapt products easily according to specific customer requirements, making us more flexible than other companies.

The developed instruments combine original engineering and optical solutions, space saving design, flexibility to adapt to different applications and long-term reliable operation providing our customers with a real competitive advantage and satisfaction.
