The TLens® Products
Imagine a simple autofocus technology, produced on a wafer scale level using the largest semi-conductor MEMS fab, capable of producing very large volumes at high yield and high quality. Imagine that this technology is suitable to replace your current Voice Coil actuator used in your camera module solution by improving its speed, its power consumption, its footprint and its robustness without degrading the optical performance. Today this solution exits: it is poLight TLens® . TLens® is the ideal solution for the latest camera phone applications such as videos with continuous-autofocus. The new poLight technology will be available in various aperature sizes and configurations. The released product is the TLens® Silver, see specification below.
The TLens® Silver is available in two versions, the TLens® Silver without package and the Packaged TLens® Silver. Below is an overview of the product specifications.
General Description The TLens® Silver can be mounted on an existing barrel-type fixed focus camera module, and is designed to support high picture quality and resolutions from 3MP and upwards, and is compatible with up to 1/3″ sensor sizes. TLens® Silver is not just a replacement of traditional VCM (Voice Coil Motor) technology for Auto Focus, it enables a range of totally new experiences, use cases and ways to build innovation.
• Response time down to <1ms
• Ultra-low power consumption <5mW
• Small footprint 3.2mm x 3.2mm
• Aperture of 1.55mm
• Focus distance from infinity down to 10cm
Potential application areas
•Camera Phones (front and back)
•HD Video Camera
tlens-status-03-03 The package TLens® has been designed in order to facilitate the integration of a TLens® on a fixed focus camera module. It has been designed in order to guarantee optimum TLens® performance over the operating temperature range, storage conditions as well as drop test according to most demanding mobile phone specifications. The package TLens® is cost effective since it has been integrated in the TLens® manufacturing processes and is minimizing the overall handling steps of TLens® integration on a camera module. The package TLens® will be 100% functionally tested (focusing range, optical quality) by poLight resulting in improved manufacturing yield of camera module. The package TLens® is made of a metal insert plastic over molding, wire bonding for electrical connections and structural bonding for mechanical performances. The package TLens® interfaces with the camera module are:
•Plastic feature for auto centring on camera module
•Top, bottom and side metal contacts to allow easy electrical contact to FPC or other camera module electrical contact.
The packaged TLens® can come with ESD and stray light cover that can be assembled at camera module level as an option. The new packaged TLens® can be added on an existing camera module in an easy and efficient way while optimizing the performances of the camera module. The package is designed to fit most existing fixed camera modules and to allow for rapid implementation of the TLens®.
