The phrase "at irradiance" is correct and usable in written English.
It can be used in contexts related to light intensity or energy received per unit area, often in scientific or technical discussions.
Example: "The experiment was conducted at irradiance levels of 1000 watts per square meter."
Alternatives: "under irradiance" or "with irradiance".
The system was tested with and without the honeycomb at irradiance of 828 W/m2 and mass flow rate spanning from 0.02 kg/s to 0.13 kg/s.
All of the cultures were incubated under a light condition with 16/8-h (light/dark) photoperiod at irradiance of 28 36 μmol m−2s−1 and temperature of 26 ± 1 °C for further development.
The opto-mechanical design permits real-sun flash illumination at a millisecond time scale so that solar cells can be characterized with only insubstantial increases in cell temperature even at irradiance levels of thousands of suns.
The leaf explants were placed on the culture and incubated in 90 × 15 mm2 Petri dishes under darkness or a light condition at irradiance of 28 36 μmol m−2s−1 as mention above in an incubator at temperature of 26 ± 1 °C.
All of the cultures were incubated under a 16/8-h (light/dark) photoperiod at irradiance of 28 36 μmol m−2s−1 (daylight fluorescent tubes FL-30D/29 FL-30D/29ina Electric Co., Taipei, Taiwan) and temperature of 26 ± 1 °C.
We also demonstrate that cone photoresponses driving pupilloconstriction adapt considerably and contribute little after 30 s, but rod photoresponses adapt less and contribute significantly to the maintenance of pupilloconstriction in response to steady-state light stimuli at irradiance levels which are below the threshold of the melanopsin photoresponse.
Samples are irradiated using a 1.07 µm fiber laser at irradiances of 1000 and 3600 W/cm2 in dry air environment (20% O2, < 1% H2O) at atmospheric pressure, producing a buoyant flow.
Porous graphite targets were irradiated with a 1.07 µm, 20-kW ytterbium fiber laser at irradiances of 0.25 4 kW/cm2.
The correlation of Ek versus irradiance showed that light acclimation mechanisms of L. papulosum decreased at irradiances below 5 mol photons m−2 per day.
Pressed cylindrical pellets with diameters of 3.2 mm and heights between 1 and 2 mm were ignited at irradiances ranging from 310 to 1446 W/cm2.
Since the silicon carbide substrate reaches its peritectic temperature (3100 K) at irradiances of 80.6 and 61 MW/cm2 for Nd YAG and excimer lasers, respectively, lower irradiances were used to achieve solid-state diffusion.
