Ecoptik (également connu comme BRD Optique) fournit ménisque lentille, dans les deux positifs et négatifs focales. Ces ménisques sont utiles lorsqu'il est utilisé avec un autre lentilles pour augmenter ou diminuer la longueur focale. Cette lentille ménisque élément configuration ne pas introduire toute supplémentaires coma ou aberrations sphériques
Ecoptik (également connu comme BRD Optique) fournit ménisque lentille, dans les deux positifs et négatifs focales. Sur l'aspect de forme, il peut être divisé en convexe et concave lentille ménisque. Sur l'aspect de l'effet, il peut être divisé en divergentes et convergentes ménisque lentille.
