LONGMONT - Lightwave Logic Inc., which earlier this year moved its corporate headquarters from Delaware to Longmont, has raised about $1.5 million of an ongoing $3 million equity offering to private investors, according to a filing made this week with the Securities and Exchange Commission.

Chief executive Tom Zelibor said Wednesday that the money will be used as operating funds to further the company's research and development.

Lightwave (OTCQB: LWLG) is working to create organic polymer materials that would speed up the transfer of data in optical-computing devices.

The company, which is pre-revenue, has 15 employees at offices in Longmont, Delaware, Washington state and Connecticut. Five spend either all or a good portion of their time working out of the Longmont office. Zelibor said there are no immediate plans to add any employees.

Lightwave, which partners with the Guided Wave Optics lab at the University of Colorado's engineering school, is in the process of building a cleanroom at its 1831 Lefthand Circle location where it can build prototype devices.
