Thermomedics - Narrow Field-of-View Silicon Lens

Caregiver with its silicon lens has a more narrow field of view (FOV) requiring more complex optic components and amplifying electronics than typical infrared thermometers.  (Its FOV is similar to a 150mm telephoto lens on a 35mm camera).  This translates to better repeatability when the distance to the skin varies and so it is less susceptible to differences in operator technique.
