Services
Quartz crystals
We manufacture precision quartz crystals for oscillator manufacturers worldwide. Our products include high-reliability SC-cut and AT-cut crystals optimised for low phase noise and long-term stability. These components serve critical applications in telecommunications infrastructure, satellite systems, and precision measurement equipment where timing accuracy is paramount.
OCXO modules
Our oven-controlled crystal oscillators deliver exceptional frequency stability across operating conditions. Available in standard and custom designs, these modules incorporate GPS synchronisation and PLL technology for applications requiring nanosecond-level timing precision in base stations, radar systems, and test equipment.
Lapping services
We provide industrial lapping and polishing for quartz substrates and other materials. Our capabilities include single- and double-sided processing up to 230mm diameter with parallelism tolerances measured in microns. This supports both production components and research applications requiring controlled surface finishes from matte to optical-grade polish.
Wildlife tracking crystals
Specialist miniature crystals for wildlife transmitter tags operate in 145-175MHz range with low power consumption. These third-overtone designs enable extended battery life in tracking systems for insects, mammals, and marine species. We support low-volume production runs from three units per channel for research applications.
Custom oscillator design
Our engineering team develops bespoke frequency control products for specialist requirements. This includes space-qualified components, medical device timing circuits, and ruggedised oscillators for industrial environments. We support clients from initial specification through prototyping to volume production of technically challenging designs.
