OPTICAL-GRADE CVD DIAMOND

Broadband Transmission: The Ultimate Choice for Optical Systems

We provide optical-grade single-crystal and polycrystalline diamonds grown using CVD (chemical vapor deposition). Leveraging their outstanding broadband optical transmission and exceptional thermal conductivity, these diamonds serve as core transmission components in high-power laser, microwave, and infrared optical systems, providing an irreplaceable material solution for advanced optoelectronic applications.

CORE PRODUCTS

Core Product Overview

Optical-Grade Single-Crystal CVD Diamond

The single-crystal structure eliminates grain-boundary scattering and provides excellent optical uniformity. Combined with precision polishing, it can achieve sub-nanometer surface roughness, making it ideal for high-power laser applications with the most stringent requirements for beam quality and transmission loss.

Optical-Grade Polycrystalline CVD Diamond

The polycrystalline structure enables the production of larger optical windows. While maintaining excellent transmission and thermal conductivity, it also offers cost efficiency, making it suitable for large-area optical windows and high-volume applications.

CORE CHARACTERISTICS

Key Performance Advantages

Broadband Transmission Range: Covers the ultraviolet, visible, infrared, and microwave bands, spanning nearly the entire spectrum

Exceptionally High Thermal Conductivity: Single-crystal diamond can exceed 2000 W/m·K, rapidly dissipating absorbed energy to prevent thermal-lens effects or thermal-crack damage under high-power irradiation

Low Optical Absorption Coefficient: Ensures extremely low losses during high-power laser transmission while preserving beam quality

High Mechanical Strength and Chemical Inertness: Resistant to wear and corrosion, making it suitable for extreme-temperature and corrosive-gas environments

APPLICATIONS

Applications

Output windows for high-power laser systems (industrial laser cutting/welding, fiber lasers)

Vacuum-sealed windows for high-frequency/high-power microwave components (gyrotrons, radar systems)

Infrared optical systems (thermal imaging devices, protective windows for infrared sensors)

Optical payloads for space and defense applications, laser weapon systems, and other extreme-environment applications
