Product Description
The OneLight Spectra is a digitally-controlled spectrally programmable light engine. Through powerful proprietary software, the Spectra allows users to create any desired mix of wavelengths instantly, and control the intensity and exposure sequences of each wavelength independently. This is the foundation of quantitative illumination.
Output to existing equipment is highly configurable via a liquid light guide connection compatible with many optical adapters. [See Accessories]
The application software allows users to control the instrument functions via a computer equipped with a standard USB 2.0 interface and high speed synchronization to other equipment via opto-isolated TTL I/O. A software API can be used to program custom applications as well. [See Software]
The OneLight Spectra is patented according to US Patent No. 6,781,691, filed on Jan 31, 2002 and granted on Aug 24, 2004. [See Intellectual Property]
Product Advantages
A single unit with the power to create and control light in software, the OneLight Spectra’s digital light technology replaces the complex assembly of mechanical components required to condition light for optical measurements.
Product Specifications
There are three different models of the OneLight Spectra, each optimized for certain wavelength ranges. These models are:
