Abstract

Characterization of LED and laser is very important to know the specifications. An electrical and optical characteristic study has been conducted on LED and Laser. The LED  used are Ultrabright red, blue, green, red, yellow and white colors and red color laser sources. Based on the results of the study stated that the current and voltage values are almost linear for voltages above 3 volts, the smallest dark current value on white LED lights, yellow LED, and laser. Yellow LED has the biggest energy loss. The optical characteristics included FWHM (Full width at half maximum) , relative intensity and angle radiated maximum. The red LED has a FWHM value and the largest angle θo, while laser has the smallest FWHM and angle θo.
