Field of View

φ 30/500
D (distance) : S (area) = 22:1
φ 40/500
D:S = 15:1
[For correct measurement]
The range of fi eld of view is equivalent to 90% of optical response (energy).
The target measured should be suffi ciently larger than the fi eld of view shown above.
When measuring a high-temperature target, keep as much distance from it as possible within the range
of the fi eld of view.
If the main body rapidly heats up, a measurement error may occur.
 When using the optional CF lens
[CS-30TAC/CS-30TAC-HT + CF]
φ 0.6/12
φ 26.5/50
* When the CF lens is attached, correction is necessary because light intensity received from the target
decreases by 20 to 30%.
When measuring a minute spot, the recommended target size is approximately 1.5 times of the fi eld
of view shown above.
