Starting in 2024, the MKS Ophir BeamSquared analyzer will be equipped with the new SP204S backside illuminated CMOS camera. This camera has several advantages over the older CCD camera (SP920) it is replacing. CMOS cameras lack the smearing found in CCD cameras. Our latest cameras also show a greatly reduced blooming effect particularly attributed to CMOS sensors. Backside illuminated CMOS sensors flip and thin the silicon, enhancing photodiode light collection efficiency for improved sensitivity. The new camera combined with our advanced BeamSquared system brings in improvement in sensitivity and M² measurement in the NIR region. The reduced pixel size in the new camera allows measurement of smaller beam sizes accurately.
