Hoenle announced the launch of its new bluepoint LED UV spot curing system. The system is available to customers starting today. The curing system combines irradiation intensity, process control, and a compact, scalable design for industrial curing applications.

Designed for applications in medical device manufacturing, electronics production, optics, and photonics, the bluepoint LED delivers irradiation intensities of up to 20,000 mW/cm² and is available in wavelengths of 365 nm, 385 nm, and 405 nm.

A key feature of the system is its modular architecture. Up to 20 LED heads can be operated via a single touch display. Each control unit supports up to four LED heads, while up to five control units can be stacked and combined. This allows users to configure the system according to their production requirements. According to Hoenle, the scalable architecture allows the system to expand as production requirements evolve.

The bluepoint LED is equipped with a detachable touch display that can be mounted either directly on the control unit or on the production machine, providing flexibility for integration into automated manufacturing environments.

As part of the product launch, Hoenle has also developed new LED heads. With a diameter of 12 mm and a length of approximately 55 mm, depending on the selected optic, the LED heads are designed for installations where space is limited while providing heat dissipation. For applications involving difficult-to-access areas, the LED heads can optionally be equipped with a 90° beam deflection adapter.

The LED heads can be connected to existing bluepoint LED devices from Hoenle and can also serve as a drop-in solution for third-party curing systems of identical dimensions.

The LED heads can be combined with optical lenses that generate irradiation diameters from approximately 3 mm to 20 mm. In addition to spot optics, Hoenle also offers a 10 × 2 mm line optic for homogeneous linear irradiation. According to the company, this is intended for applications such as active alignment, where uniform exposure is required.

The bluepoint LED also features power control with adjustable output from 10% to 100%. Integrated Process Flow Control (PFC) allows users to program and store irradiation sequences, with up to six individual programs available. According to the company, these functions support repeatable curing processes in automated production environments.

For machine integration, the system provides a PLC interface for switching, monitoring, and status feedback of the LEDs, while external analog inputs allow individual power adjustment for each LED head. The bluepoint LED also provides a signal input for LED switch-off according to current safety guidelines. An RS232 interface is included for external control and transmission of exposure parameters. Additional accessories include extension cables for the LED heads in various lengths and adapters for operating up to four foot switches per control unit.

Typical applications include the spot curing of UV-curable adhesives in automated production processes. The bluepoint LED is intended for manufacturing environments including disposable medical devices, electronics assembly, bonding of optical components, and photonics applications. Hoenle stated that cooperation with Hoenle Adhesives (formerly Panacol) enables curing and bonding processes for these applications.

With a service life exceeding 20,000 operating hours, irradiation intensities of up to 20,000 mW/cm², flexible optics, and process control capabilities, the bluepoint LED is designed for precision UV curing applications.
