The BPC300-C is a complete measurement solution for the automatic characterisation of photochromic (sun-darkening) prescription contact lenses. Multiple samples can be mounted in an automatic lens changing carousel, and analysed sequentially and automatically under a variety of irradiance and ambient temperature conditions. Spectral and temporal transmittance measurements can be performed in darkness and under the intense irradiation of a nominally AM2 (but highly configurable) conditioning beam, which allows darkening and fading-back kinetic studies. Full characterisation sequences including preconditioning, faded spectral optical density measurements, darkening dynamics measurements, darkened spectral optical density measurements, fading dynamics measurements, and spectral optical density measurements after fading can all be performed sequentially on up to 6 samples without requiring further user interaction.
