EssentOptics AKRA Monochromatic Optical Monitoring Systems

The EssentOptics AKRA Monochromatic Optical Monitoring Systems are designed to measure transmission and/or reflection of optical coatings during the vacuum deposition process. The system is based on EssentOptics original design of monochromator and control software for visualization of the measurement process on the system’s control display.

The system can be chosen to operate within a wide spectral range: 200-1100 nm, 200-1700 nm, 380-1100 nm, 380-1700 nm, 380-2600 nm, 1,5-5 um. The AKRA system allows accurate control of layer growth on any one selected wavelength as well as a full broadband scan after completion of each layer. Additionally, the theoretical spectra of each layer can be uploaded to the system’s software and displayed on the screen – this option is very helpful for comparing the calculated and actual values and termination of the deposition process once the desired value is achieved.

The installation of the AKRA Systems requires no modifications to the vacuum chamber in most cases. The set of supply includes all necessary connection flanges and components designed to fit into majority of the vacuum coaters.
