Hyderabad. 27 June, 2025. Zen Technologies Limited (“Zen”) announced the grant of its 54th Indian patent, titled “Single ILU Long Pass Filter”, marking a significant breakthrough in laser- based military training systems.
Long-Pass Optical Filter
The newly patented long-pass optical filter enables the seamless integration of visible and infrared laser beams into a single, stable output. This innovation enhances the accuracy, realism, and responsiveness of combat training simulators. Unlike traditional systems that rely on separate beams and often face issues related to alignment and durability, Zen’s compact and robust solution delivers superior optical performance under rugged field conditions, while significantly reducing the need for recalibration and maintenance.
Export Opportunities
In addition to bolstering domestic capabilities, this technological leap opens significant export opportunities for Zen. With several nations actively seeking to modernize their military training infrastructure, Zen’s high-performance, cost-effective, and low- footprint solution is well-positioned to address international demand. The patented filter system’s compact design and modularity make it ideal not only for full-scale simulator environments but also for mobile deployment and export-oriented models.
Substantial Stride in Self-Sufficiency
This development further demonstrates India’s growing capability to design and deliver advanced defence technologies through homegrown innovation. By reducing reliance on foreign components and emphasizing domestic R&D, Zen contributes to building a more self-sufficient and globally competitive defence manufacturing ecosystem. The patent adds to Zen’s expanding intellectual property portfolio and highlights the strategic importance of sustained investment in indigenous technological advancement
Zen Technologies Limited is a pioneer and leader in providing world class state-of-the art Defense Training and Anti-Drone solutions and has a proven track record in building training systems for imparting defense training and measuring combat readiness of security forces.
