Agilent / HP / Keysight 81628B

This High power optical head also enables fully traceable measurements within a wavelength ranging from 800nm to 1700nm. This feature, together with the fast and accurate measurement of optical power levels up to +38dBm, reduces test time, increases yield and accelerates time to market. The optical head combined with integrating sphere ensures safe and flexible operation. The sphere can be rotated to optimize the input port position and allows almost any connector to be safely connected with the input port.
