A Huawei engineer explains the free-form lens advantages of the Huawei Mate 40 Pro

Huawei issued a publication in which one of its engineers explained the advantages of free-form lens technology in the Huawei Mate 40 Pro. The translation from the Chinese language is somewhat approximate but we have got to the bottom of it.

The free-form lens is undoubtedly one of the most prominent features of the Huawei Mate 40 Pro. Instead of using the traditional spherical or aspherical optical lenses, the 20MP wide-angle camera in Huawei’s new flagship phone uses an asymmetrical lens with a complex and uneven surface. With this, engineers are trying to address one of the biggest problems with wide angle cameras, and the issue at stake is distortion.

But distortion is not the only problem Huawei is trying to solve. Smartphones today are quite heavy so the freeform lenses will partially help solve this problem as they are lighter and thinner as well. Perhaps in the future when this technology is improved, we will get cameras that do not protrude from the backsides of our smartphones. That’s because freeform lenses require fewer elements. Moreover, the new lens technology allows more light to pass into the sensor, which improves the performance and quality of the camera.

Huawei has been working with this lens for over two years now and is finally ready to be used widely in consumer devices. The company plans to do this with telephoto lenses as well since they have a different kind of distortion of their own. Reducing lens thickness is more important here.
