OEM spectrophotometer ESCORT SM
for optical coating deposition monitoring
(Precise Broadband optical monitor)
SOL instruments has many years' experience in development and production of optical monitoring
systems for various technological processes.
OEM spectrophotometer ESCORT SM is a high-end instrument based on innovative investigations
of spectral devices and precise measuring systems, with no analogs on the market.
OEM spectrophotometer ESCORT SM provides precise and rapid measurements of emission
(E) spectrum of evaporated material, transmission (T) or reflected (R) spectra of deposited coating,
the automatic control and optimization of deposition process (Control&Optimization System).
?
Purpose- ESCORT SM spectrophotometer is a specialized OEM complex that measures optical coating parameters in the process of deposition and after the process, in the vacuum sputtering chambers of various types.
- ESCORT SM spectrophotometer has measuring channel of broadband monitoring (S125) and measuring channel of single wavelength monitoring (M450)
- ESCORT SM spectrophotometer enables to measure transmittance (T) or reflectance (R) simultaneously through two measuring channels and displays these coating parameters for automatic deposition process control.
- The measuring channel of broadband monitoring allows simultaneous measurement of a spectrum for all wavelength ranges. The measuring channel of single wavelength monitoring measures coating parameters at the selected wavelength precisely and synchronously with the broadband channel.
- The single wavelength channel allows precise spectrum measurements after the deposition process by scanning in the defined spectral range with the set step.
Reflection coefficient measurement of rotated sample in the vacuum chamber during the coating deposition process.?
Examples of use Transmission coefficient or reflection coefficient measurement of rotated sample in the vacuum chamber during the coating deposition
Functions- Measurements of emission, transmission and reflection spectra
- Measurements of emission value, transmittance, optical density value and reflectance at fixed wavelength
- Kinetic measurements at selected wavelength
- Statistical characteristics calculation
Features - Monochromatic and broadband optical monitoring with two independent measuring channels: broadband (BBOM) and single wavelength (SWOM)
- High performance original optical schemes
- 3,5" embedded personal computer that performs rapid processing of the measurement results and data transferring to the external software that controls a vacuum chamber
- Embedded color TFT-LCD Touch Screen module based on 3,5" PC or РС104 and internal software for stand-alone operation. External computer connection through high-speed interface 10/100 Ethernet, connection to a company's local network
