Technical Data
- The diameter of the incident parallel light beam can be expanded or contracted by a fixed factor.
- Reflective design, achromatic, suitable for broadband light sources.
- It exhibits high reflectance across a wavelength range from 450 nm to 20 μm.
- Low wavefront error of λ/10
Chongfan Technology’s reflective beam expander employs two silver‑coated spherical mirrors and features a low‑aberration design. Following optimization, the system’s wavefront error is less than λ/10 (for an incident beam diameter of 1 mm). It can expand (or contract) the diameter of a collimated input beam by a fixed magnification factor. The expander’s input and output ports are threaded with SM05 and SM30 interfaces, ensuring compatibility with our SM‑threaded lens tubes; additionally, it incorporates four M3 mounting holes for integration with our 30‑mm coaxial systems. After being focused by the reflective beam expander, polychromatic light can be coupled into an optical fiber using our reflective collimator.
Chongfan Technology also offers a range of customization services, including tailored specifications for special dimensions, operating wavelengths, beam‑expansion ratios, and more. For specific customization requirements, please contact Chongfan Technology’s technical support team.
