Thorlabs 評(píng)估板和激光二極管驅(qū)動(dòng)器
評(píng)估板
MLDEVAL評(píng)估板是一種開放型電路板，可將我們的OEM級(jí)激光二極管驅(qū)動(dòng)器與幾種常用接頭連接。它包含母頭DB9接頭，可用于連接到消應(yīng)力電纜的激光二極管，還包含螺絲終端，用戶可用其直接連接TO封裝激光二極管。通過(guò)USB或可以連接5 VDC電源的螺絲終端可以供應(yīng)電源。
兩個(gè)電位器控制激光二極管的工作設(shè)定點(diǎn)。Pset/Iset電位器對(duì)激光器電流的調(diào)節(jié)范圍在0 mA-200 mA之間，可用于恒定電流和恒定功率激光器。TIA增益電位器能限制監(jiān)測(cè)二極管的電流，因而只能用于恒定功率驅(qū)動(dòng)器。為了遠(yuǎn)程調(diào)制激光器的光學(xué)輸出功率，可在母頭SMA接頭施加電壓。
評(píng)估板的總尺寸為105.8 mm × 56.0 mm × 14.1 mm(包含母頭DB9接頭)。邊角處有四個(gè)?3.2 mm通孔，用于自定義安裝。
激光二極管驅(qū)動(dòng)器，用于評(píng)估板
我們的OEM級(jí)激光二極管驅(qū)動(dòng)器包含鍍有半孔的接頭，接頭可通過(guò)自動(dòng)組裝系統(tǒng)安裝。為了便于安裝在MLDEVAL評(píng)估板，每個(gè)驅(qū)動(dòng)器預(yù)先安裝在了子板上。zui后將子板插入評(píng)估板上匹配的插孔即可，這樣，就可以在實(shí)驗(yàn)和測(cè)試環(huán)境中快速使用這些驅(qū)動(dòng)器。
安裝驅(qū)動(dòng)器之前，根據(jù)所選驅(qū)動(dòng)器和激光器的引腳類型，需將評(píng)估板上的幾個(gè)開關(guān)設(shè)置在正確的位置。有關(guān)正確位置的詳細(xì)說(shuō)明，請(qǐng)看評(píng)估板手冊(cè)的第4和第5章。選定了驅(qū)動(dòng)器，有些開關(guān)不能改變，安裝驅(qū)動(dòng)器時(shí)就不能進(jìn)行操作。
