摘要: There are many types of component that able to produce light and the is produced based on angle wavelength lens. Light penetration depends type material used. The tests done using basic electronic components which including emitting diode (LED), laser infrared source. From component, there two line, one with an without. It known only produces a straight line while thickness from both LED, source increase distance. results show different must use lenses they suitable for all properties.
