OES Spectrometers

OES Spectrometers (Optical Emission Spectrometers for OEMs) optimized for SEMICON applications including plasma monitoring/end-point detection and reflectometry (with the addition of a flash lamp). The OES-Star features unmatched throughput and SNR, spectral coverage and < 1 nm resolution). Our new OES Family, OES-Star, VS70-MC and InVizU all include our latest “Multi-Communications interface” electronics (MC= EtherCAT, Ethernet, USB-2). The Invizu integrates both a linear CMOS sensor for UV-VIS and a TE-Cooled INGAAS sensor, which extends the spectral coverage to 1700 nm.

The M116 is a new imaging multi-spectra spectrometer (200-1050 nm) with a high speed Scientific 2D CMOS sensor which allows the monitoring of multiple tools or multiple areas of a plasma,with 8, 16 or 32 fiber optic channels, fully simultaneously acquired. Its sensor features < 2e- readout noise, an e-shutter and a USB3 interface. For integration in a Reflectometer, custom fiber optic bundles can be designed to your requirements.
