WOBURN, Mass., Sept. 24, 2012 — Ultrahigh-brightness LED light engines with integrated fluorescence excitation filters are being offered by Innovations in Optics Inc. LumiBright LE light engines use state-of-the-art LED technology and interference filters with hard dielectric coatings for fluorescence excitation in life sciences instrumentation and medical illumination. The ability to add excitation filters to each light engine ensures that the excitation energy spectrum is optimized for the application. Applications for integrated fluorescence excitation filters include gel and blot imagers, real-time polymerase chain reaction systems, cytometers, colony counters, microplate readers and gene array readers. Excitation filters are available at several center wavelengths and bandwidths. They feature in-band peak transmission >92% and out-of-band blocking >OD7. Patented nonimaging optics direct LED light into a desired cone angle, while producing uniform angular and spatial output. The two standard half angles are 20° and 41°. Available peak LED wavelengths range from 365 nm through the near-infrared, or as broadband white, configured as dense chip-on-board LED arrays with single- or multicolor options. The light engines offer intense and stable optical power, short warm-up time, high energy efficiency, low maintenance and long life. Some models can be fiber-coupled and supplied with a photodiode for feedback light control.
