Ultra-Broadband Metallic Mirrors
Avantier is a well-established custom optics manufacturer with over 55 years of experience in the field. They specialize in producing high-precision Ultra-Broadband Metallic Mirrors tailored to meet specific customer specifications. Here are the key features and details about these mirrors:
Key Features of Ultra-Broadband Metallic Mirrors:
- High Reflectance Over a Broad Spectral Range: These mirrors are designed to provide high reflectivity across a wide spectral bandwidth. They are effective at reflecting light over a broad range of wavelengths, making them versatile for various applications.
- Enhanced Reflectance in the Visible Range: These mirrors are optimized to provide enhanced reflectance in the visible range of the electromagnetic spectrum. This characteristic is valuable for applications that require good reflectivity within the visible light spectrum.
- Effective Over Wide Angles of Incidence: Ultra-Broadband Metallic Mirrors are designed to maintain their high reflectance properties even when light strikes them at wide angles of incidence. This feature ensures their performance remains consistent across different viewing angles.
- Standard Diameters: These mirrors are available in standard diameters ranging from 12.7 mm (0.5 inches) to 50.4 mm (2 inches). Standard sizes make them suitable for integration into various optical systems and setups.

Coating Options
Avantier offers three different metallic coating options for these mirrors, each with its unique spectral characteristics:
- Aluminum: Aluminum coating provides a good general-purpose mirror with high reflectance in the visible range. It is commonly used for applications that require reflection within the visible spectrum.
- Silver: Silver-coated mirrors offer very high reflectance over the visible and near-infrared range. This makes silver an excellent choice when you need maximum reflectivity in these wavelength regions.
Gold: Gold coating is the preferred choice for infrared (IR) applications, especially at wavelengths greater than 2 microns. Gold-coated mirrors are well-suited for IR imaging and sensing applications.
These mirrors undergo a manufacturing process that begins with the application of a reflective metal film, which is subsequently followed by the addition of a dielectric overcoat. This dielectric overcoat serves a dual purpose: it provides protection to the underlying reflective metal layer while simultaneously augmenting the mirror’s overall reflectivity and performance.
Avantier’s proficiency in the field of custom optics manufacturing guarantees that these Ultra-Broadband Metallic Mirrors are tailored precisely to meet the specific specifications and demands of their customers. As a result, these mirrors find applicability across a diverse spectrum of optical applications in fields such as research, industry, and technology.
