The ML9002A is a compact handy power meter with a measurement level as wide as other more expensive instruments. Seven optical sensors are available for different wavelengths, measurement levels, and optical input types . Each can be calibrated for three common wavelengths so absolute optical power can be read directly. Each optical sensor can either be incorporated directly in the main frame or connected using a connecting cord. The ML9002A can be used to check opt ical disks, optical printers and optical communications systems and can back up on-side operations as a powerful multifunctional measuring instrument for maintenance.
