Precision instruments, metrology, fluorescence, low-noise analog electronics – that’s what we do.
Weight gain at NIST
We like to measure things – and NIST is our source of the best measurement advice.
Radiometry Explained by NIST
The measurement of light is complicated by a variety of units and concepts that are not used in other fields.
Radiometric Measurements
It’s easy to confuse the units of LED light output. Steradians, luminous intensity, etc.
CCD Cameras, Eyes, And Physics
This tech note was motivated by the question – how does the response of our eyes differ from the response of a CCD camera sensor.
Vision Response vs. Planck’s Black Body Curve
Color temperature is based upon the idea of a Planck black-body radiator.
