Broadband Metallic Mirrors |
These mirrors are affordable with good reflectance in a wide range of wavelength. Mirrors are available in aluminum, silver and gold coating and at any angle of incidence. Light absorption coating, reflection is slightly reduced. |

Dielectric Mirrors |
These mirrors are designed for high reflectance with low loss. The coating is resistant to hard scratches. To be used from 0-45 degrees angle of incidence. |
Round: φ10, (0.5”), 15, 20, 25, (1.0”), 30, 40, 50, (2.0”) |

|
Super Mirrors |
Our Super mirrors are ultra-high performance mirrors which provide near 100% reflection in order to maximize the performance of a Fabry-Perot resonator cavity. |
Round: (0.5”), 25, (1.0”), 30, 50 |

Synthetic Fused Silica |
|
Femtosecond Laser Mirrors |
This mirror is designed to provide low wavelength dispersion suitable for use with ultra-short pulse lasers with 100 femtosecond or less. |
Round: (0.5”), (1.0”), 30 |
