LDC205C In Stock

The LDC205C by ThorLabs is a benchtop laser diode current controller that is an essential tool for high-precision applications that require a reliable and versatile solution. It can be operated in both constant current and constant power modes, making it an ideal choice for a range of specific tasks. The LDC205C delivers superior performance as a highly accurate, precise injection current controller for laser diodes and LEDs.

The LDC205C is equipped with an enhanced compliance voltage of over 10V, making it compatible with blue laser diodes. The LDC205C also boasts a 5-digit LED display that can show critical information such as laser current, optical power in mW, photodiode monitor current, or laser current limit. Additionally, it features analog control input and output and can operate with designated polarities of laser diodes and photodiodes, making it highly user-friendly. Grounded operation provides the LDC205C with exceptionally low noise capabilities, as well as advantages in transient suppression and stability. To ensure top performance, the device should be recalibrated annually. It is also compatible with a CAB400, which is essential when using the controller with a laser diode mount.

One of the most critical features of the LDC205C is the various safety features built-in to protect against damage to the laser diode. The soft start function protects against undesired transients, while adjustable current limitation prevents unintentional current values. An open circuit function switches the output off if connection to the laser is interrupted, while electronic short-circuit protection guards against accidental ESD and induced current transients. A line failure protection turns the laser current off if a power failure occurs. The LDC205C also comes with an interlock interface that includes a safety lock to prevent unintentional use, cable disconnect or monitoring, an external emergency switch, and an external LED to indicate when the laser is switched on. With dimensions of 146 mm x 66 mm x 290 mm without operating elements, and weighing less than 3.1 kg, the LDC205C is compact and lightweight, making it ideal for a range of applications.
