2.5 Optics
The vario optics of the CTratio allows a smooth focusing of the optics to the desired distance.
Optics Focus adjustable in the range
SFV 300 mm till infinity
The following tables show the diameter of the measuring spot for some selected distances. The spot size
refers to 90 % of the radiation energy.
The distance is always measured from the front edge of the sensing head.
As an alternative to the optical diagrams, the spot size calculator can also be used on the Optris website
(
https://www.optris.global/spot-size-calculator ) or via the Optris calculator app. The app can be downloaded
for free from the Google Play Store (see QR code).
D = Distance from front of the sensing head to the object
S = Spot size
