*1 The measurement accuracy in the specification is (strictly) limited to the calibration conditions of our factory.
・Note that specifications are subject to change without prior notice for product improvement purposes.

Field of view

(Unit: mm)
  • BFL-30 / standard lens

  • With no lens attached (fiber only)


・The device is calibrated to the standard lens upon shipment.
When using an optional lens or the fiber only, TEACH/ε (emissivity) adjustment must be performed.
・The field of view stated above are measurement diameters with an optical response of 90%.
・The size of the measurement target must be sufficiently larger than the measurement diameters shown in the above diagram.
