Broadband Fused Silica Dielectric High Reflective Mirrors Product Discription
Broadband Fused Silica Dielectric High Reflective Mirrors are high-reflectivity mirrors specifically designed for applications requiring high reflectivity across a wide spectral range. Utilizing fused silica as the substrate and combined with multi-layer dielectric coating technology, these mirrors provide high reflectivity across a broad wavelength range while minimizing absorption and scattering losses in the substrate. Asin Optics manufactures and customizes Broadband Fused Silica Dielectric High Reflective Mirrors with high reflectivity and a 20/10 scratch-dig rating. In addition to fused silica substrates, we also offer BK7, CaF₂, MgF₂, and YAG as substrate options, suitable for optical systems such as laser systems and imaging optical paths.
Broadband Fused Silica Dielectric High Reflective Mirrors Key Advantage
- Our Broadband Fused Silica Dielectric High-Reflectivity Mirrors achieve an average reflectivity of over 99.5% across the UV, visible, and near-infrared regions, such as 400–1000 nm, 700–1400 nm, and 1200–2000 nm.
- Fused silica, used as the substrate, offers excellent thermal stability, a low coefficient of thermal expansion, and high-temperature resistance, making it suitable for high-power laser systems and operating environments with significant temperature fluctuations.
- Our Broadband Fused Silica Dielectric High Reflective Mirrors, featuring a dielectric coating design, lack metal absorption layers, which reduces optical energy loss while increasing the laser damage threshold. Additionally, the dielectric coating is dense, corrosion-resistant, and offers excellent environmental stability.
- For this high-reflectivity mirror, we can achieve a surface quality of R10. We can also achieve a parallelism of 1/20λ.
- We offer flexible AOI customization, accepting custom AOI values within the range of 0° to 45°.

Fused Silica Laser Mirrors Applications
- Femtosecond and Picosecond Laser Systems
Conventional metal coatings or narrow-band mirrors can cause spectral narrowing, pulse broadening, and energy loss. Broadband dielectric coatings maintain a reflectivity of over 99.5% across the entire pulse spectral range, ensuring pulse integrity. Additionally, dielectric coatings have very low absorption and can withstand high-power ultrashort laser pulses. - Spectrometers
Raman or fluorescence spectroscopy requires the transmission of excitation light and signal light with a very wide bandwidth through the same optical path. Broadband high-reflectivity mirrors can maintain high reflectivity across the entire wavelength range without the need to replace optical components. This allows a single optical path calibration to cover the entire spectrum, improving experimental efficiency. - High-Power Laser Processing
In high-power semiconductor or fiber laser beam combining systems, it is necessary to maintain broad-spectrum reflectivity across multiple adjacent wavelengths to combine beams from different modules. Dielectric mirrors have low absorption and are less prone to thermal effects; they can also serve as beam combiners to merge multiple laser sources into a single coaxial output.
