Nanostart AG of Frankfurt, Germany, has augmented its share in Microlight Sensors from 19 to 31 percent by investing through its Nanostart Singapore Early Stage Venture Fund. The increased share stems from payment of a second tranche from the round of financing concluded in 2010. The additional funds will be used for commercial expansion, including the buildup of marketing and sales structures in Asia and development of innovative sensor technologies. Microlight Sensors, based in Singapore, supplies fully integrated optical sensor and scanning systems for applications in the homeland security and commercial spectral instrumentation systems markets.
