Index Dispersion Enhanced Optical Monitoring (IDEM)

Instead of continuously struggling to get your coating system to produce films that match your design program, why not use the SpectraLock IDEM to allow your design program to accurately predict the product your machine will produce?

What is IDEM?

Two fundamental properties define the full spectrum optical properties of a transparent coating: its Thickness and its Refractive Index dispersion

Current Thin Film Design Programs and Optical Coating Systems use standard materials reference table values for refractive index dispersion in the design and monitoring of coatings. Unfortunately, the refractive index dispersion for each material in a given coating system process deviates from the standards by a small amount. These errors multiply with each additional layer applied requiring expert compensation by specialists for successful results.

The SpectraLock IDEM provides calibration of the exact Refractive Index Dispersion for each material and process you use. Thereafter, your Thin Film Design Program and the Optical Monitoring Controller produce optical coatings that precisely match their design every time without iteration or error.

How Does IDEM Work?

Prior to fabrication of designed coatings, a 2000nm-3000nm calibration layer is deposited on witness and sample substrates for each coating process to be used in your system. The SpectraLock measures the Refractive Index Dispersion of the coating on each witness chip and stores the curves for future use. The substrate samples are then measured to determine the monitor to work ratio for each material.

These process Index Dispersions and Monitor to Work ratios are then translated and loaded into both your Thin Film Design Program and the SpectraLock Controller for precise coating thickness control at each layer.

The SpectraLock is the only commercial instrument capable of measuring In-Situ the broadband Optical Index Dispersions produced by your coating machine.
