MKS Instruments Announces Ophir® PD300RM-UVA, Irradiance and Dosage Sensor with Flat Spectral Response for Use with Narrowband and Broadband Sources

Andover, MA – February 24, 2021 – MKS Instruments, Inc. (NASDAQ: MKSI), a global provider of technologies that enable advanced processes and improve productivity, has announced the Ophir® PD300RM-UVA Irradiance and Dosage Sensor. Calibrated over the UVA and violet spectral range (350-450nm), the sensor provides a flat spectral response that is forgiving of inexact wavelengths, wide bandwidths, and wavelength shifts (e.g. due to heating). This allows for measuring both narrowband (lasers) and broadband sources, such as LEDs, without the need to know the exact wavelength. The sensor also supports measuring sources at different wavelengths simultaneously. It is designed to analyze light sources, including for UV curing and drying of polymers, paints, and other UV responsive materials that are used in industrial applications, such as semiconductor processing and additive manufacturing.
