Lens maker Fraen has again applied its nested collimator intellectual property, this time to a 50mm diameter optics that will fit in MR16 applications – the earlier 75mm types are aimed at PAR20s. +/-6° beams, or narrower, can be expected from CoBs with a light emitting surface unser 6.5mm across. Applications are expected in architecture, ...
