“…To assess the stability, we measured the signal that a green GTLS produced on a calibrated photodiode (Thorlabs S130C sensor head with PM100D power meter) at a fixed position over time. While work by Mikhal'chenko et al [15] has demonstrated in principle the stability of tritium radioluminescent sources, and others have praised their stable properties [11,16], we found little quantitative data, and it is unclear how these results would apply to generically sourced GTLSs, given their proprietary formulations and manufacturing methods.…”

We propose a practical method for radiometrically calibrating cameras using widely available gaseous tritium light sources ( betalights ). Along with the gain (conversion factor) and read noise level, the predictable photon flux of the source allows us to gauge the quantum efficiency. The design is easily reproducible with a 3D printer (three-dimensional printer) and three inexpensive parts. Suitable for common image sensors, we believe that the method has the potential to be a useful tool in microscopy facilities and optical laboratories alike. This article is part of the theme issue ‘Super-resolution structured illumination microscopy (part 2)’.

An analysis of rocket AMF‐VB‐41 measurements of the spatial variation of the I6300/I5200 intensity ratio in the dayside cleft and polar cap ionosphere is reported. The measured variation of the I6300/I5200 ratio is not consistent with significant production of 6300 Å emission via the reaction N(²D) + O2 → NO + O(¹D). An upper limit to the O(¹D) yield of 0.1 is obtained for this mechanism.
