Abstract: The present invention uses the concave hybrid architecture to form a wide angle projection lens with large numerical aperture. The wide angle projection lens includes a refraction system and a reflection system, wherein the refraction system includes a first lenses group containing a plurality of spherical lenses and at least one spherical lenses, and a second lenses group containing at least two aspheric lenses and at least one spherical lens, and the at least one spherical lens is configured between any two of the at least two aspheric lenses. The present invention is beneficial in reducing the wide angle projection lens in size and is able to effectively overcome the problem in low geometric efficiency, and enable the ultra-short focus projector have compact and portable advantages.
