Product DescriptionProduct DescriptionBroadband Dielectric Mirrors (BDMs) are optical components designed to reflect a wide range of wavelengths with high efficiency. Unlike narrowband HR mirrors, BDMs use multi-layer dielectric coatings to achieve reflectivity >99% across broad spectral bands (e.g., 400–700 nm, 700–1100 nm). These mirrors are ideal for applications requiring uniform performance across multiple wavelengths, such as fluorescence microscopy, laser communications, and white-light interferometry .SpecificationProduct:Broadband Dielectric MirrorsMaterial:Fused Silica/BK7Clear Aperture:>90%Diameter Tolerance:+/-0.1mmBevel: Break sharp edgesFlatness (PV): <1/10L@633nmSurface Quality: 10-5Thickness Tolerance: +/-0.1mmFAQFAQ of Broadband Dielectric MirrorsQ: How do Broadband Dielectric Mirrors achieve broadband reflectivity?A: Broadband Dielectric Mirrors use alternating layers of high and low refractive index materials (e.g., TiO2 and SiO2) to create constructive interference across a broad wavelength range. Q: Can Broadband Dielectric Mirrors be used at angles other than 45°?A: Broadband Dielectric Mirrors are typically designed for 45° AOI, but custom designs can accommodate other angles. However, reflectivity and bandwidth may shift with angle changes. Q: What is the trade-off between bandwidth and reflectivity?A: Wider bandwidths generally result in slightly lower peak reflectivity. Our Broadband Dielectric Mirrors balance these factors to meet application-specific requirements. Q: Are Broadband Dielectric Mirrors suitable for high-power continuous-wave (CW) lasers?A: Yes, Broadband Dielectric Mirrors with optimized coatings can handle CW lasers up to kilowatt levels. Always specify your laser parameters for optimal design.Extended Product RangeProduction LineCompany HistoryCertifications
