BPC300-C photochromic lens test

The BPC300-C is a complete solution for automatic characterization of photochromic (sun-darkening) prescription contact lenses. Multiple samples can be mounted in the temperature-controlled water bath that houses an automatic lens carousel, and can be analyzed sequentially and automatically, which allows for machine readable files and PDF reports of measured characteristics. 

Spectral and temporal measurements of optical transmittance/density can be performed at various temperatures in darkness and under intense irradiation of a nominally AM2 (but highly configurable) conditioning beam, which allows kinetic studies of darkening and fading. 

The complete characterization sequences, including preconditioning, spectral optical density measurements after fading, darkening dynamics measurements, spectral optical density measurements after darkening, fading dynamics measurements and spectral optical density measurements after fading can all be performed sequentially on up to 6 samples without the need for user intervention.
