MKS Announces New Ophir® Large Beam Profiler with Small Pixel Size for Higher Resolution Measurement of Large and Divergent Beams

Andover, MA – September 13, 2022 – MKS Instruments, Inc. (NASDAQ: MKSI), a global provider of technologies that enable advanced processes and improve productivity, has announced the Ophir® SP504S Beam Profiling Camera. Designed to measure large and divergent beams, the SP504S camera accurately captures and analyzes wavelengths from 340-1100nm for beam sizes from 45µm up to 23mm x 23mm. The camera features a wide dynamic range of 44.6dB, a lowest measurable signal of 0.25nW/cm2, and high accuracy at NIR wavelengths. The SP504S camera provides the industry’s smallest pixel size of 4.5 µm – up to 3X smaller than competitive offerings – which allows measurement of laser beams with higher spatial resolution and smaller beam sizes. That makes the camera ideal for large beam diameter applications that require high resolution or when beam tracking is needed over a large area, such as laser material processing, VCSEL / LEDs, and medical aesthetics.
