Optical monitoring for ophthalmic optics applications
LEYBOLD OPTICS WLP
Bühler Leybold Optics offers a broad portfolio of optical measuring devices which includes a white-light photometer (WLP). This is a proven tool used to measure the integral visible transmittance in-situ on the substrate to be coated via visible light transmission (VLT). It allows for continuous quality checking during the coating process and can halt the coating process once the optical threshold has been reached. This makes the LEYBOLD OPTICS WLP the ideal tool to achieve exact absorption values.
With the focus set on the visible wavelength, this device is perfectly adapted to the requirements of the ophthalmic markets. It can also represent a cost-attractive solution for specific applications in the precision optics markets.
Optical monitoring for optoelectronics and precision optics applications
LEYBOLD OPTICS OMS 5100
The LEYBOLD OPTICS OMS 5100 is the premium benchmark setting device for in-situ optical monitoring. The system is equipped with a doublebeam photometer based on a monochromatic measurement of reflectance or transmission. Bühler Leybold Optics’ optical monitoring system is equipped with both single- and multi-wavelength capabilities, automatic pre-calculation and linear online trigger-point correction. Results from layer design programs can be transferred directly. LEYBOLD OPTICS OMS 5100 is customarily fully integrated into the machine’s control system so as to ensure fully automated operation and highly reproducible and stable coating results.
LEYBOLD OPTICS BBM
The LEYBOLD OPTICS BBM broadband monitoring system is an in-situ optical monitoring system used to control the layer thickness directly on the substrate. It is used for production and process development, as well as for quality management. During broadband monitoring, the individual layers of the process are terminated based on the measured spectral information. The actual spectral curve is then displayed on the monitor.
The system consists of a halogen light source, a compact multi-channel spectrometer with CCD array, and a PC-unit with the BBM software program onboard.
