Manufacturer: EssentOptics Ltd

Product name: PHOTON RT

Scanning spectrophotometer.

New this year: Expanded spectral range to 190-4000 nm, new feature: average polarization measurement, redesigned interface.

Features: designed specifically to run wide range of optical measurements of thin film coatings – transmittance, reflectance, polarizationdependent measurements in wide angular and spectral range. Average polarization (S+P)/2, optical density 0-4D, etc. All measurements are done automatically and without any additional external fixtures or accessories.

Used for: Lab, Process analysis

Measurement Mode: Transmittance, Reflectance, Angular dependent measurements, Polarization dependent measurements, Optical density, Integral values

Suggested applications: Optical measurement of parts with coatings – all types of optical filters, mirrors, AR coatings, cube polarizers etc in UV, VIS and NIR range (190-4000 nm)

Primary benefits: easy and convenient way to measure optics with coatings, focused specifically on optics.

Unique features: All measurement features are built-in, designed just for optics so it does not have any extra elements: neither in design nor software.
