● 說(shuō)明：
1、注意：該激光二管發(fā)射的激光為不可見(jiàn)光，有可能對(duì)人眼造成傷害。激光管工作時(shí)，嚴(yán)禁直接注視其端面。
2、激光管需要合適的驅(qū)動(dòng)電源，瞬時(shí)反向電流不能過(guò) 25μA，反向電壓不能過(guò) 2V，否則會(huì)損壞激光管。
接通電源前先插好激光管，電源初始輸出電壓應(yīng)為，電流調(diào)節(jié)時(shí)應(yīng)緩慢增加或減少，電流沖擊損壞激光管。
測(cè)試激光管：或拔起激光管須在斷電后進(jìn)行。切勿帶電插/拔激光管，否則激光管將會(huì)損壞、失效。
3、激光管應(yīng)當(dāng)存放或工作于干燥環(huán)境，以結(jié)露，結(jié)露會(huì)損壞激光管。
4、在較高溫度下工作，會(huì)閾值電流，降低轉(zhuǎn)換效率，加速激光管的老化。
5、輸出功率高于指定參數(shù)工作，會(huì)加速激光管老化。
6、激光管需要充分散熱或在制冷條件下使用。
7、激光二管屬于靜電敏感器件，應(yīng)做好靜電措施，在人體有良好接地的情況下方可拿取，否則激光管很容易被靜電擊穿，造成激光管失效。靜電可配帶靜電手腕帶。
