Earlier this year, we had reported on LG Innotek and Corning working on Liquid Lens technology that could seemingly benefit the smartphone photography. Now, an from the latter firm had touted the various benefits of this new lens technology.
In an interview with TheElec, Frederic Laune, business manager at Corning Varioptic Lenses stated that liquid lens can help with changing local lengths in cameras. The manager also added that the company is looking to expand the applications of this technology in various other industries like the medical and industrial fields. For those unaware, liquid lens is basically filled with liquid materials inside the physical lens that can change the curvature of the lens by using currents and voltages to control the focal length of the camera.
Laune stated that liquid lens can be used to solve the focal length changing issue, which is when the distance between the camera and subject is constantly changing. He said that the new lens technology can basically focus on a particular object even if there were varying distances in between. Conventional lens technology usually had the lens being placed close to the image sensor or further away from it to maintain the focus on the object. However, these mechanical solutions are vulnerable to external shock and increase the power consumption of devices while being slow.
So, liquid lens technology aims to be a power efficient alternative, which is more effective and quicker as well. Furthermore, this is the reason why industrial cameras rarely use these lens solutions, as per the Manager. Liquid lens is also durable against shakes external shocks, making it practical in various fields like augmented reality.
