Ultra Broadband Dielectric Mirrors are manufactured using all dielectric multi-layer coatings of alternating high and low index layers. These are specifically designed for use at 45 degrees angle of incidence. The mirrors are offered for use in applications where high-reflection over a broad wavelength range is required.

◦Visible, near infrared and multiple wavelengths are covered with a single mirror.
◦These mirrors have many advantages over a metal mirror including very little deterioration with age and that it is durable and easy to clean and maintain.

▶Please consult our Sales Division for assistance in your selection and for customized products. (customized on outer diameter, wavelength characteristic, etc.) Please use the inquiry sheet.
W3800
▶Also available are our surface flatness guarantee (HTFM) mirrors with accuracy guarantee after surface coating.
W3002
▶Please refer to here for Wavelength Characteristic Data (Reference Data, EXCEL file format).

Attention

▶Reflectance of dielectric mirrors will vary according to the polarization of the input beams.
▶The un-coated rear surface of the mirror is polished and the arrow on the side of the substrate points towards the coated surface. Reflectance of laser line mirrors are different according to the polarization of input beams. S-Polarization has high reflectance with a wide reflective bandwidth compared with P-Polarization.
▶The reflectance specification listed is at random polarization or (P-Polarization reflectance + S-Polarization reflectance) / 2.
