Hönle: New Bluepoint LED UV Spot Curing System for Adhesive Curing

Hoenle’s Bluepoint LED was developed for curing adhesives on small surfaces in applications such as medical technology, electronics manufacturing, optics, and photonics. The system generates 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 new system is its modular architecture. Up to 20 LED heads can be controlled via a single touchscreen display. Each control unit supports up to four LED heads, and up to five control units can be stacked and combined with one another. This allows users to tailor the system precisely to their production requirements. This scalable architecture allows for system expansion. The Bluepoint LED is equipped with a modern, detachable touchscreen display that enables simple and intuitive operation. The display can be mounted either directly on the control unit or on the production machine, offering maximum flexibility for integration into automated manufacturing environments.

New and Improved LED Heads

As part of the product launch, Hoenle has also developed new, improved LED heads. These compact new LED heads can also be connected to existing Bluepoint LED units from Hoenle. With a diameter of just 12 mm and a length of approximately 55 mm—depending on the selected lens—the LED heads are exceptionally compact. Thanks to their slim design, they are ideal for installations in confined spaces while still ensuring effective heat dissipation. For applications in hard-to-reach areas, the LED heads can be optionally equipped with a 90° beam angle adapter. Thanks to the compact dimensions of the LED heads, the Bluepoint LED also serves as a direct replacement for curing systems from other manufacturers with identical dimensions. To ensure maximum flexibility for various curing tasks, the LED heads can be combined with a range of optical lenses that produce spot diameters from approximately 3 mm to 20 mm. In addition to the proven spot optics, Hoenle now offers a new 10 × 2 mm line optic that enables homogeneous linear irradiation. This makes the device particularly suitable for applications such as active alignment, where precise and uniform exposure is essential. The Bluepoint LED also features intelligent power control with an adjustable power range from 10% to 100%. Thanks to the integrated process flow control (PFC), users can program and save complete irradiation sequences, with up to six individual programs available. These features enable repeatable and reliable curing processes in automated production environments.
