Thorlabs' advanced UV Curing LED Systems are designed to cure adhesives that need to be exposed to reproducible high-intensity light at UV wavelengths. Complete systems are available with center wavelengths of 365 nm, 385 nm, 395 nm, and 405 nm. Five operation modes allow fine control of the duration and intensity of emission. Up to 10 different settings for intensity and exposure time can be stored in configuration profiles. The integrated power density detector enables calibration of the emission time based on the current power density of the LED.
Five Operation Modes
- Continuous Mode: The intensity of the emitted light can be continuously adjusted up to the user-set maximum current limit (by default, the absolute maximum of the chip). The intensity scale can be displayed as current in mA, % of maximum current, or the output irradiance (in mW/cm²).
- Timer Mode: This mode allows the user to limit the exposure time for a selected intensity.
- Slope Mode: This mode allows the user to gradually increase or decrease the intensity over a chosen time interval. Simply choose the initial and final intensities and the intensity will vary in a linear fashion during the chosen time period.
- Configuration Mode: 10 different user-defined timer mode profiles can can be stored.
- Irradiance Mode: Use this mode to recalibrate all settings or to measure the irradiance of the LED source.
The integrated power density detector enables calibration of the emission time based on the current power density of the LED source. An acoustic signal can also be activated to generate beeps at determined time intervals. The output of the curing system is SM05-threaded; optics can be easily interchanged to produce different beam spot sizes and shapes.
Compared to conventional arc-lamp UV systems, these LED systems offer many advantages, such as an intense, uniform UV radiation profile and a long lifetime of 10,000+ hours. It requires much less energy, needs no warm-up time, and exhibits low IR heat emission. The system has no moving parts (passive, fan-less cooling) and is maintenance free. Additionally, the source contains no mercury and generates no ozone during the curing process.
See below for optical accessories for the UV Curing LED Systems. The beam diameter can be changed to 9 mm or 1 mm with the CS20A2 Collimation Adapter or CS20A3 Focus Adapter, respectively. One CS20A2 Collimation Adapter is included with each UV curing LED system. While the LED system can be used without an optic, the output light will diverge to 32 mm diameter measured 20 mm from the output.
See below for electrical accessories for the UV Curing LED Systems. The CS20A1 Foot Switch is designed as an alternative means for turning the LED on and off without having to use the controller or software. The CAB-CS20 adapter cable allows the driver in any of our UV curing LED systems to be used to drive our mounted LEDs or fiber-coupled LEDs.
Safety glasses are recommended when using our UV Curing LED Systems. One pair is included with the purchase of a UV Curing LED system. In addition, Thorlabs offers several pairs of glasses that are appropriate for use with these systems. Please visit our Laser Safety Glasses page for detailed information about each of these items. Since the correct choice of laser safety eyewear depends upon many local factors that cannot be evaluated remotely, including the beam path, light source parameters, and lab environment, we recommend that you discuss your needs with your organization's laser safety officer to determine the best option.

|Driver Unit Operating Specifications
The CAB-CS20 adapter cable (sold separately below), allows the driver unit of Thorlabs UV curing systems to drive any Thorlabs mounted LED or fiber-coupled LED. This flexibility enables our UV curing systems to be adapted for use in more stable or space-constrained setups using our complete families of optomechanical components, fiber patch cables, and fiber optomechanics. We also offer a much broader wavelength selection from deep UV to NIR for both our mounted LEDs and our fiber-coupled LEDs, down to as low as 265 nm and 285 nm, respectively.
Using Driver Unit with Thorlabs Mounted LEDs
For applications that require high power and stability, any Thorlabs mounted LED can be connected using the CAB-CS20 adapter cable to the driver unit of the CS20K2, CS20K3, CS20K4, or CS20K5. The LED can be mounted using standard optomechanical components as shown in the example to the right (top). The parts list is given as an example and can easily be adapted for the space and stability constraints of any particular setup. Please contact Tech Support for help on selecting the appropriate items for a specific application.
Using Driver Unit with Thorlabs Fiber-Coupled LEDs
For curing applications with space constraints, a fiber-coupled LED can be connected using the CAB-CS20 adapter cable to the driver unit of the CS20K2, CS20K3, CS20K4, or CS20K5. The LED can be mounted using standard optomechanical components as shown in the example to the right (bottom). We also offer a wide range of fiber collimators to ensure the output is suitable for curing applications. The parts list is given as an example and can easily be adapted for the space and stability constraints of any particular setup.
