Title
Maximum Reachable Distance with Ulisse2 when using two IRs
Brands
Summary
How to calculate the distance using 2 illuminators instead of one, for which the distance is known?
Environment
- ULISSE 2
- UPTIRN
- ILLUMINATORS
Resolution
Since this is a luminous flux involving a surface, the light (visible) or radiant (IR) irradiation is reduced with the square of the variation of the distance, therefore by doubling the irradiation the inverse function is applied, i.e. the distance increases by the square root of the variation in irradiation.
Hence the scientific theory reports: √2 = 1,41
This is the multiplier to obtain the maximum distance using two lights of the same type instead of one.
Eg. UPTIRN 10° 850nm gives 240mt. distance, thus using two illuminators you will get 240*1,41 = 338mt.

Additional Notes
Please always note:
The distances and the performance depend on the camera/lens utilized and on the environmental light conditions.
Internal Notes
This rule can be applied to every product using 2 same illuminators as well as to the illuminators themselves.
