Abstract[English]
The present invention provides an external lens and a projection module. The external lens sequentially comprises, from a first side to a second side, a first lens group having a negative focal power and a second lens group having a positive focal power, wherein the first lens group and the second lens group are non-coaxially arranged, the first lens group comprises at least one lens having a negative focal power, and the second lens group comprises at least one lens having a positive focal power. The present invention solves the problem of large size of external lenses in the prior art.[French]
La présente invention concerne une lentille externe et un module de projection. La lentille externe comprend séquentiellement, d'un premier côté à un second côté, un premier groupe de lentilles ayant une puissance focale négative et un second groupe de lentilles ayant une puissance focale positive, le premier groupe de lentilles et le second groupe de lentilles étant agencés de manière non coaxiale, le premier groupe de lentilles comprenant au moins une lentille ayant une puissance focale négative, et le second groupe de lentilles comprenant au moins une lentille ayant une puissance focale positive. La présente invention résout le problème de grande taille de lentilles externes dans l'état de la technique.[Chinese]
