MKS Instruments, Inc., a global provider of technologies helping to transform the world, introduced the Ophir ® BeamSquared ® SP204S-PRO and Ophir ® BeamSquared ® SP1203 M two-beam transmission analyzers at SPIE Photonics West 2025 .
The BeamSquared SP204S-PRO M 2 Analyzer is a precision beam shaping and etching system for advanced laser manufacturing in semiconductor manufacturing, display manufacturing, medical systems, defense and industrial applications. This compact and fully automated instrument quickly and accurately measures the propagation characteristics of standard and large diameter CW and pulsed lasers over an extended Rayleigh range (up to 40 meters). The BeamSquared SP204S-PRO M 2 Analyzer is designed for manufacturers in high-precision manufacturing environments who need to accurately characterize key beam parameters such as M 2 , beam position, astigmatism and beam symmetry . It is the newest member of the Ophir BeamSquared beam spread analyzer family, delivering significant improvements in waist position measurement of large diameter beams and 3% astigmatism measurement accuracy that is essential for optimizing advanced optical systems. The BeamSquared SP204S-PRO M 2 Analyzer provides more accurate beam delivery and quality parameters while maintaining device-to-device consistency in laser parameter measurements. This is a critical feature for continuous production environments.
The BeamSquared M2 beam propagation analyzer series also includes the BeamSquared analyzer. ® SP1203 (including the Ophir SP1203 GigE Beam Analyzer). This high-resolution beam analyzer can accurately measure lasers with larger Rayleigh lengths and smaller beam diameters (up to 150 µm in the SWIR and NIR ranges) that need to be focused to a narrower spot. This enables the BeamSquared SP1203 M2 system to be used in a wider range of advanced applications such as communications, advanced manufacturing (welding, cutting, 3D printing), autonomous vehicles (LiDAR) and medical devices (ophthalmology and optical tomography).
“The evolution of advanced laser systems has driven leading manufacturers to seek more accurate ways to validate performance for their customers’ demanding applications,” said Reuven Silverman, general manager, Ophir Photonics Products. “Manufacturers face significant errors in astigmatism and caustic position measurement, as well as quality control spanning the UV to NIR spectrum. The new BeamSquared M 2 analyzer addresses these issues. The analyzer offers the most accurate product on the market, combining ISO 11146 compliance, precise beam caustic measurement, and extensive laser characterization capabilities, enabling process manufacturers to continuously tune their lasers with optimal precision and reliability.”
The BeamSquared M 2 analyzer includes Ophir BeamSquared software, an optical transmitter, and a high-resolution camera. The latest analyzer features longer optical transmission and patented UltraCal™ advanced calibration software, providing highly accurate beam analysis for lasers with an extended Rayleigh range of up to 40 meters. The software measures beam propagation characteristics in both the X and Y axes, including waist diameter, total angular divergence, waist position, Rayleigh length, M2 or K factor , BPP, astigmatism, and asymmetry . The system displays 2D or 3D beam profiles to visually verify the behavior of the beam through the focus. Features include a 3D slice display and the ability to add 3D views to reports. Reports can also incorporate beam caustic charts in addition to setup information, laser measurements, and many other statistics. An automation interface through a .Net component allows users to build custom applications that combine laser beam analysis with the processing power of the BeamSquared system.
All BeamSquared M 2 analyzers can be mounted horizontally or vertically to optimize bench space. Each machine is equipped with a focusing lens, typically in the range of 400-1000 mm. The BeamSquared SP204S-PRO analyzer is equipped with a specially designed calibration lens that is optimally designed for use with long range Rayleigh lasers (40 m) that include both long waist positions and large beams.
