Measurement Systems

We supply equipment for monochromatic optical real-time monitoring (OMS), optical low-coherence interferometry  (OLCI),  optical measurement of film thickness  (OTFP – optical thin film probe) and equipment for optical density measurement of metallized films (DISS).

Solutions

Optical monitoring systems (OMS)

Optical low-coherence interferometry (OLCI, HP OLCI)

Optical thin-film probe (OTFP)

Dual in-situ sensor (DISS)

OMS

Double-beam photometer based on monochromatic measurement of reflectance or transmission. Measuring technology for automated monitoring in optical production processes.

OLCI, HP OLCI

The Leybold Optics OLCI (optical low-coherence interferometry) series of optical measuring devices were developed for contactless measurement of thickness and surface profile of samples transparent to the measured wavelength of 1310 nm. Leybold Optics OLCI instruments measure absolute thickness with a precision of +/- 1µm, relative thickness with +/- 10 nm and allow the creation of xy-profiles of sample thickness. OLCI comes with its own PC and is used in the glass industry, in ophthalmics, medical coatings and packaging.

OTFP

OTFP (optical thin film probe) allows fast, precise and contactless measurement of film thickness of smooth, transparent films in the nanometer and micrometer range using thin film interference. Semi-transparent layers and semiconductors can be measured with a spectrometer at λ 200-1100nm and a thickness range of 50nm – 50µm.
