In 1990, development began on an advanced technology light scattering photometer to replace an older instrument that could not detect the higher protection factors offered by new gas mask designs. The result was the Laser Photometer 8587A, which is still used today to test filter efficiency.

The photometer owner asked TSI to develop a modern version of the Laser Photometer 8587 that would retain data continuity with the original version. Without data continuity, a large number of legacy studies could not be directly compared to new studies. The result is the Laser Photometer 8587A.

The Model 8587A can also be used in HEPA filter scanning systems to detect penetration of large, high efficiency filter assemblies.
