TriLite, a former SPIE Start-up Challenge finalist, is presenting the 'world's smallest' laser beam scanner project display at Photonics West this week. 

Trixel 3 is the company's first laser beam scanner light engine based on Infineon’s 2D MEMS mirror, and is targeting augmented reality (AR) glasses. 

The MEMS mirror, the company says, negates the need for complex relay optics between the mirror and waveguide/holographic input. With no relay optics required, the overall module size is shrunk to a volume of less than 1cm3 with an ultra-light weigth of 1.5g.

Last October, TriLite raised €8 million to bring mass market augmented reality eyewear to the consumer market. 

In addition to its hardware, the company has invested heavily in software that makes it simple for developers to adopt its solutions. The TriLite calibration module (TCM) software simplifies system integration, by providing real-time correction of lens errors, distortions, and colour shifts (true tone), and allows the size and complexity of the optical system to be reduced.

Peter Weigand, CEO at Trilite, said: 'We’re proud to present the first laser beam scanner demonstrator powered by Infineon’s unique 2D MEMS mirror. This is the first step in the collaboration between TriLite and Infineon focusing on a light engine with the very smallest form factor.'
