OptiCore™ Diamond

Optical-Grade Single-Crystal CVD Diamond for Photonics, Spectroscopy, and Research Applications

OptiCore™ Diamond is a high-quality single-crystal CVD diamond platform developed for optical, photonic, spectroscopy, thermal, and general research applications that require excellent surface quality, broad optical transmission, and a controlled crystalline substrate.

Unlike NVCore™ products, OptiCore™ Diamond is not intentionally engineered for a defined NV-center population. Instead, it is optimized as an optical-grade diamond substrate with a nitrogen concentration below approximately 10 ppm, making it a practical and cost-effective choice for experiments where ultra-low nitrogen electronic-grade material is not required.

OptiCore™ Diamond is supplied with a (100) crystal orientation, double-side polished surfaces, and AFM roughness below 5 nm. Standard formats include 3 × 3 × 0.3 mm and 3 × 3 × 0.5 mm, with full-corner geometry and a controlled thickness tolerance (different sizes available on demand).

Its combination of optical transparency, low surface roughness, mechanical robustness, and high thermal conductivity makes OptiCore™ Diamond suitable for a broad range of laboratory and device-development applications.

OptiCore™ Diamond is particularly suited for:

• Optical transmission and absorption studies
• Photoluminescence spectroscopy
• Raman spectroscopy
• Laser and photonics experiments
• Diamond substrate studies
• Thermal transport and heat-spreading research
• Defect and impurity studies
• Optical window and transparent substrate applications
• General CVD diamond research and device integration
• Applications where ppm-level nitrogen is acceptable and electronic-grade purity is not required

Product selection guidelines

Because OptiCore™ Diamond is not specifically processed for NV-center generation, the concentration and charge state of naturally occurring NV centers are not guaranteed. For applications requiring intentionally engineered ensemble NV centers, NVCore™ Ensemble or NVCore™ Premium would be more appropriate. For ultra-low nitrogen backgrounds and user-controlled NV creation, an electronic-grade diamond host would be preferred.

Choose NVCore™ Ensemble or NVCore™ Premium for ready-to-use ensemble NV centers, OptiCore™ for general optical and spectroscopy applications, and QuantumCore™ Ultra for ultra-pure diamond intended for custom defect engineering, electronics, and quantum sensing research.
