摘要 |
An optical analyzer 100 includes a light emitting diode (LED) 102. LED 102 has a body 104 pervious to light and a PN junction semiconductor 105. The body 104 has a surface portion 107 where a primary light emitted from semiconductor 105 is divided into a first light and a second lights. The first light is reflected at a sample 109 and then received by a detector 111 while the second light is detected by a detector 113. An optical property of the sample 109 is determined by the use of outputs of the detectors 111 and 113. <IMAGE> |
