PC GUI
DLC pro的直观PC GUI允许从计算机进行完全控制（需要Windows 8或更高版本）。 只需连接到实验室中的任何激光器，并从其当前设置开始。
电子邮件通知
我们通过时事通讯通知有关软件的新更新。 只需发送电子邮件至dlcpro [at] toptica.com，并附带“订阅”即可，并确认您感兴趣的方面。
以太网络
将DLC pro连接到局域网可以从计算机进行远程控制，例如 通过PC GUI和命令界面。 支持DHCP和手动IP配置。
LabVIEW示例
在示例程序中演示了将DLC pro的控件集成到LabVIEW中的方法，请参见下面的下载部分。
气压补偿
此功能可通过校正测得的气压变化来提高稳定性，并使波长更稳定。
配置管理器
配置管理器允许返回以前保存的激光设置。尝试新的设置，例如锁定参数会被大大简化。
功率稳定
作为每个激光器的一部分，可以激活功率稳定反馈环路。 可以达到的带宽会在下表的当前控制模块CC-500和CC-5000的规格中列出。
宽扫描模式
宽扫描允许记录和显示高分辨率光谱扫描。 这对于CTL和DFB pro系统尤为重要，可以在激光二极管的整个波长范围内进行扫描。
屏幕截图
只需按一下按钮，即可将触摸屏界面的屏幕快照保存到USB驱动器。

Additional Product Information
TOPTICA Python Laser SDK (updated with every DLC pro software release) makes the command interface of the DLC pro (and other TOPTICA lasers) easily available in Python. The documentation of the command interface is provided by the DLC pro Command Reference, which is included in any DLC pro software package in the documentation folder. How to use the Python SDK is explained in the project homepage of the package
LabView example VIs for connecting to DLC pro (no technical support, also included in any DLC pro update) shows how a connection to a DLC pro is established in LabVIEW.
