Field of view

(Unit: mm)
  • ・How to read the diagram
    At 300 mm from a measurement target, the product measures the average temperature of a 25 mm diameter surface area (surface area within the circle).
    ・The laser marker is located 13 mm to the left of the light axis.
    ・The measurement fields 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 figures shown in the above diagram.
