@Pimaxusa @Matthew.Xu Would pimax consider the development of new aspheric or hybrid fresnel-aspheric lenses using this formula or one of the formulas in the related articles provided in these journal articles linked below?
Maybe plastic aspherics are the solution to keep the cost and weight low ? The supposed cost of custom lenses is as little as $2000, and around $2-$10 each in bulk orders per unit according to this article. (these guys also do custom lenses)
Also,there have been talks within Pimax regarding Pimax looking at new lense developments(also quoted below), @Pimaxusa can this be an item of discussion in the next update?
