Multi crystals optics
Multi crystal optics (2, 3 or 4 reflections) such as a Channel Cut or Bartels monochromator, decreases the ration λ/λ. However this increase in wavelength selectivity is possible only diminished intensity of X-Ray beam.
These monochromators can be either Germanium or Silicon and of varied orientations including (440, 220, 111).
MF2/4Ge Model
The 4 bounce monochromator has been designed with 2 separate but integrated mechanical mounts which contain the channel-cut crystal. A design feature of this mount is that provision has been made to allow the selection of either 4 or 2 reflections as required.
Applications are mainly those of high resolution reflection measurements or line profile studies.

Description: The EP200™ Series monochromators are designed to measure a single wavelength of light in the range of 185–925nm. When used with Verity’s system controllers and the proper optical input path, the EP200 Series provides robust endpoint detection for production or research applications.
The EP200 Series is used extensively in semiconductor and related thin film applications for endpoint detection in etch, CVD etchback, photoresist stripping and related applications. The EP200Mmd is designed for manual adjustment of wavelengths. The EP200Msd permits computer-controlled spectral scanning through the use of a stepper motor, hardened lead screw assembly and position encoders. These elements allow the scanning monochromator to reposition itself for different wavelengths when a process recipe changes or a new product calls for monitoring a new endpoint emission. Performance of the EP200 Series monochromators is enhanced by its wide spectral range, superior wavelength resolution (up to 0.2nm) and extraordinary dynamic range of the photomultiplier tube (PMT).

Our Oriel Cornerstone 260 1/4 m Monochromators are economical, fully automated, multi-grating instruments with dual output ports and exceptional optical performance. We offer a dual grating and a triple grating model; both were designed for fast, automated, continuous scanning over a broad spectral range. Simply program your filter, grating, and port changeover points, and walk away while Cornerstone 260 automatically scans from the UV through the far IR. Other standard features include a built-in electronic shutter, filter wheel control, USB 2.0 or RS-232 and IEEE-488 communications, and a family of interchangeable gratings and slits.
