DLC pro：數(shù)字控制用于可調(diào)二極管激光器的全數(shù)字控制器
極低的噪音和的控制
方便的本地和遠(yuǎn)程操作
智能鎖定功能
DLC pro是一個(gè)平臺(tái)，可驅(qū)動(dòng)TOPTICA的所有可調(diào)二極管激光器：適用于所有波長的控制器。
二極管激光器的性能在很大程度上取決于其控制器DLC pro是一個(gè)基于數(shù)字基礎(chǔ)的二極管激光控制器，DLC pro是一個(gè)基于數(shù)字基礎(chǔ)的二極管激光控制器，它對(duì)獲得所有關(guān)鍵參數(shù)的優(yōu)良性能至關(guān)重要:窄激光線寬的低電流噪聲，穩(wěn)定運(yùn)行的出色的溫度控制和頻率調(diào)諧的壓電控制。
為了釋放此高性能控制器的全部潛能，提供了直觀的用戶界面：借助觸摸屏和旋鈕，可以輕松調(diào)整掃描，放大觀察到的功能，激活頻率鎖定等。數(shù)字基礎(chǔ)還可以實(shí)現(xiàn)全面的遠(yuǎn)程控制，包括Windows計(jì)算機(jī)的GUI和命令界面。該接口對(duì)所有編程語言開放；提供了Python SDK。
許多應(yīng)用需要參考激光的頻率。 TOPTICA提供滿足所有需求的解決方案：便捷的軟件解決方案DLC pro Lock直接集成到DLC pro中，而FALC pro提供了高性能鎖定。
DLC pro是二極管激光控制器的基準(zhǔn)：具有優(yōu)良性能的硬件，以以前沒有的便利性運(yùn)行。
Python 支持 | 作為TOPTICA的Laser SDK的一部分，我們提供了DLC pro的Python支持，可通過pip安裝輕松獲得。 該軟件包又Python軟件包索引（PyPI）提供。 |
PC GUI | DLC pro的直觀PC GUI允許從計(jì)算機(jī)進(jìn)行全部控制（需要Windows 8或更高版本）。 只需連接到實(shí)驗(yàn)室中的任何激光器，并從其當(dāng)前設(shè)置開始。 |
以太網(wǎng)絡(luò) | 將DLC pro連接到局域網(wǎng)可以從計(jì)算機(jī)進(jìn)行遠(yuǎn)程控制，例如 通過PC GUI和命令界面。 支持DHCP和手動(dòng)IP配置。 |
LabVIEW示例 | 在示例程序中演示了將DLC pro的控件集成到LabVIEW中的方法，請(qǐng)參見下面 |
氣壓補(bǔ)償 | 此功能可通過校正測(cè)得的氣壓變化來提高穩(wěn)定性，并使波長更穩(wěn)定。 |
配置管理器 | 配置管理器允許返回以前保存的激光設(shè)置。嘗試新的設(shè)置，例如鎖定參數(shù)會(huì)被大大簡化。 |
功率穩(wěn)定 | 作為每個(gè)激光器的一部分，可以激活功率穩(wěn)定反饋環(huán)路。 可以達(dá)到的帶寬會(huì)在下表的當(dāng)前控制模塊CC-500和CC-5000的規(guī)格中列出。 |
寬掃描模式 | 寬掃描允許記錄和顯示高分辨率光譜掃描。 這對(duì)于CTL和DFB pro系統(tǒng)尤為重要，可以在激光二極管的整個(gè)波長范圍內(nèi)進(jìn)行掃描。 |
屏幕截圖 | 只需按一下按鈕，即可將觸摸屏界面的屏幕快照保存到USB驅(qū)動(dòng)器。 |
