Emissivity
A surface treatment is used to create a spectrally flat emissivity of > 0.970 (3µm to 5.5µm), > 0.950 (8µm to 14µm).

Intelli-Probe (iProbe)
The iProbe is an intelligent temperature sensor that is calibrated independently of the blackbody system.

To re-calibrate the system you need only exchange the probe with a recently calibrated one.

No special equipment is required and there is no down time in the test area.

Uniformity
The Infinity blackbody incorporates design and construction features that maximize spatial uniformity

and minimize convection influences resulting in typical surface uniformity of > 98% of set absolute temperature

less ambient temperature or 0.010ºC whichever is greater, over 90% of the emitting surface area.

Milli-Kelvin Temperature Stability
SBIR has developed unique temperature measurement and analog-to-digital conversion circuitry with integrated control logic

that results in extremely responsive temperature control.

True set point and precise milli-kelvin control have been achieved allowing for precision testing at contrast levels of 1 milli-kelvin.
