I made some new friends in the industry of Infrared thermometers. :)
And in their Users manual there is a nice picture that demonstrates in detail the specifications regarding Distance Spot Ratio of the advanced technologically Infrared thermometers.

It does not require much of imagination that the suggested Distance Spot Ratio of what an electrician needs to have so to aim on a circuit board or electrical panel needs to be 50:1.
The benefits of 50:1 are very specific.
a) You can get one very accurate reading by the distance of 70-80cm away ( That is a safe distance regarding high voltage)
b) You can have an accurate reading even up to two meters ( extremely high temperature sources )
c) The diameter of the beam is 16mm = 1.6cm that is almost good enough for aiming circuitry breakers.
In such Infrared thermometers of 50:1 and with one so narrow in diameter beam, those dual pointing lasers is a must have too as aiming assistance.
All the above details they do present clearly the profile which one successfully designed 50:1 Infrared thermometer must have.
What I would describe as even higher in quality Infrared thermometer in the 50:1 Distance Spot Ratio,
it would be the one with even narrower diameter of beam at less than 16mm. ;)
