High Reflection (HR) Dielectric coatings can be produced for a diverse range of substrates for the VIS, NIR, SWIR, and MWIR spectral regions.
Main Page
Dielectric mirrors, also known as Bragg mirrors, are a high-performance solution for achieving precision reflectivity in optical systems. Unlike metal coatings, dielectric mirrors use multi-layer thin film structures to reflect specific wavelengths with exceptional accuracy and minimal absorption.
Thanks to advanced thin-film deposition techniques, dielectric mirrors offer superior purity, uniformity, and compatibility with complex geometries. This makes them a preferred method for applications requiring high reflectivity, spectral selectivity, and long-term durability.
Custom Engineered Coatings
Intlvac systems can produce a wide variety of multilayer dielectric coatings tailored to your exact specifications. We support a broad selection of substrates and coating designs for use in the Visible (VIS), Near-Infrared (NIR), Short-Wave Infrared (SWIR) and Mid-Wave Infrared (MWIR) spectral regions.
Whether you need a basic high-reflectivity mirror or a custom optical filter with sharp edge performance, Intlvac delivers coating solutions that meet both optical and environmental demands.
Available Dielectric Filter Types
1. Bandpass Filters
Function:
Transmit energy only within a selected wavelength band while rejecting all others.
Applications:
-
Laser systems
-
Fluorescence imaging
-
Spectroscopy.
Durability Standards:
2. Long Wave Pass (LWP) Filters
Function:
Transmit wavelengths longer than a specified cut-on value; block shorter wavelengths.
Applications:
-
IR imaging
-
Photodetector protection
-
Remote sensing.
Durability Standards:
Same as listed above.
3. Short Wave Pass (SWP) Filters
Function:
Transmit wavelengths shorter than a specified cutoff; block longer wavelengths.
Applications:
-
UV filtering
-
Fluorescence excitation
-
Optical instrumentation.
Durability Standards:
Same as listed above.
4. Neutral Density (ND) Filters
Function:
Reduce the intensity of incident light without altering its spectral profile. This is achieved by controlling the thickness of a metallic or dielectric layer to reach a target transmittance level.
Applications:
-
Laser attenuation
-
Imaging systems
-
Beam shaping.
