Lightweight Optical Structures

For the fields of space remote sensing and high-energy laser beam control, we have developed a series of high-precision, lightweight structural components, achieving weight and volume reductions of 30%-70% while maintaining surface accuracy.

The lightweight materials we use are

Silicon Carbide

Silicon carbide combines high contrast stiffness, low coefficient of thermal expansion, and high thermal conductivity, making it the preferred material for large space mirrors.

Silicon

Single-crystal silicon has high thermal conductivity, low density, and high purity, making it suitable for lightweight mirrors in the mid-infrared band.

Glass-Crystal

Glass-ceramics have a low coefficient of thermal expansion, making them suitable for large, precision optical systems and lithography machines.

Fused Quartz

Fused quartz possesses excellent uniformity and resistance to laser damage, making it a lightweight component suitable for high-power laser systems.

Typical lightweight products

Silicon carbide aspherical mirrors

Currently, we can process:

  • Materials: RB-SiC, SiC coating.
  • Surface shapes: Planar, spherical, aspherical, off-axis aspherical.
  • Diameter: Φ100~800mm.
  • Lightweight structures: Open-back hexagonal honeycomb, open-back aperture, irregularly shaped network structure.

All surfaces and materials are integrally sintered, eliminating the need for splicing. Furthermore, we employ precision grinding and ion beam shaping for error control.

Lightweight Silicon Mirrors

We can currently process high-precision lightweight silicon mirrors:

  • Materials: Monocrystalline silicon, polycrystalline silicon.
  • Diameter: Φ50~600mm.
  • Lightweight Structure: Triangular mesh, rectangular mesh.

Quartz and Microcrystalline Glass

Currently, we can process:

  • Quartz and microcrystalline elongated perforated mirrors.
  • Quartz and microcrystalline aspherical mirrors.

Other lightweight products we can process

Silicon prisms

Sapphire irregular-shaped window microcrystalline mirrors, quartz square mirrors

L-shaped microcrystalline glass reference fixtures
