White LED Module Suits Bio-Medical Apps

Groomed for bio-medical and analytical designs, the OTLA-0130 broadband white LED light module integrates a white LED with additional monochromatic LED die to expand spectral output. The component also features a small light-emitting source size of less than 2 mm in diameter, which allows coupling to fiber and focusing optics. Each white LED wavelength—395 nm, 470 nm, 630 nm, and 660 nm—can be individually addressed for separate pulsing and intensity balancing. Potential applications include fluorescence, absorbance, transmittance, reflectance, and color-metric measurements. OPTO TECHNOLOGY INC., Wheeling, IL. (847) 537-4277.
