Dielectric Mirrors

Dielectric Mirrors

Dielectric Mirrors, also known as Bragg Mirrors consist of multiple layers of dielectric coating materials deposited onto glass surfaces typically. OptoSigma offers a wide variety of dielectric mirrors that are appropriate for high power lasers, broadband light sources in a varity of applictions. Whether you need a laser line solution, or, an ultra-broadband solution, we have a great selection. Regardless, if you cannot find what you need from our standard offerings, contact us direct for a custom product.

  • Broadband Dielectric Mirror

    Description

    This section may be titled Broadband Dielectric Mirrors, although, you will also see these named Ultra-Broadband Dielectric Mirrors and the ranges are incredibly wide, with high reflectance throughout!  With UV mirrors from 245nm-400nm and UV to NIR from 300nm-2000nm!  WOW!  Reflectance values up to 98% average across the bands.  These are specific for use at 45-Degree AOI and are suitable for applications that require high reflectance across a broad spectrum.  As always, if one of our many standard products do not meet your needs, ask us for a custom solution!

  • Laser Line Mirrors

    Description

    These Laser Line Dielectric Mirrors are suitable for demanding laser applications.  You will find a variety of sizes starting at 12.7mm diameters, up to 50.8mm and specific wavelength mirrors starting from the Ultraviolet, 157nm, up to Nd: YAG, 1064nm.  Our substrates are highly polished to 10/5 Scratch Dig and Surface Flatness, λ/10.  Additionally, these offer high laser damage thresholds up to 20J/cm2.  Do not forget to pair these with our MHX Mirror Mounts to enable low thermal drift and high stability.  As always, if one of our many standard products do not meet your needs, ask us for a custom solution!

  • Wide Angle Dielectric Mirrors

    Description

    This family of Dielectric Mirrors are specified for use from 0-45 Degree AOI with reflectance values of Ravg>99%.  They range in size from 10mm round to 50mm and in wavelengths from 405nm to 1550nm.  These are also suitable for demanding laser applications and substrates are polished to a flatness of λ/10 and 10/5 Scratch Dig.  As always, if one of our many standard products do not meet your needs, ask us for a custom solution!

  • High Power Mirrors

    Description

    This section contains a variety of High Power Yb Dielectric Mirrors.  Wavelengths from 257nm, 343nm, 515nm & 1030nm and in sizes from 12.7mm to 50.8mm in diameter.   The substrate material is Fused Silica for low thermal expansion, and they are polished to a flatness of λ/10 and 10/5 Scratch Dig.  The laser damage thresholds go up to 28J/cm2.  As always, if one of our many standard products do not meet your needs, ask us for a custom solution!
