1. 365nm UVA Main Peak — Cures Both Shallow and Deep UV Adhesives
The 365nm main wavelength lands precisely in the UVA band while also covering multiple effective curing lines such as 405nm and 436nm. It cures shallow UV adhesives and also meets the excitation needs of deep-layer photoinitiators, making it compatible with the vast majority of UV adhesives, UV inks, and photoresist materials on the market.
2. Quartz Fiber Coupling — Fixed-Point Cold-Light Output
After concentration, light is delivered through a quartz fiber-optic light guide. Thermal radiation in the working area is low, enabling close-range, precise curing of heat-sensitive parts such as camera modules and optical communication components without thermal damage to surrounding materials.
3. High-Intensity Output from a High-Pressure Mercury-Xenon Lamp
Continuing the 275W preset-type UV lamp architecture used by the original SP-11, it maintains high illuminance output and is compatible with the SP-11 irradiator’s motorized shutter and timer control system (0.5–999 s in 0.1 s steps; 1,000–9,999 s in 1 s steps).
4. Supply and Cost Advantages of a Domestic Alternative
Compared with the long ordering cycles of the imported original, the AKL-275UH has ample stock and controllable lead time, at a per-lamp cost significantly lower than the OEM. It suits batch replacement on UV curing lines with multiple machines and frequent lamp changes.
