Ultrafast Mirror — Model UFPM20-UVB

Operating wavelength 340 nm-425 nm, Ø50.8 mm, thickness 12 mm, substrate UV fused silica.

Product Description

  • Low Group Delay Dispersion Dielectric Coating, using Ion Beam Sputtering (IBS) Process
  • Wavelength range from 340 nm to 1700 nm
  • Lower Coefficient of Thermal Expansion and extremely high thermal shock stability
  • Suitable for high-power femtosecond pulse lasers and imaging fields
  • For 45° incidence

The substrate material of LBTEK ultrafast mirrors is fused silica, with a high-reflectance coating on the surface being a low group delay dispersion dielectric coating deposited using ion-beam sputtering (IBS). During the ion-beam sputtering process, a high-energy electric field accelerates the ion beam toward the target, causing ions to be sputtered from the target and releasing more ions, which ultimately deposit the coating on a rotating substrate. Using ion-beam sputtering enables high repeatability in batch coating and low coating layer thickness errors, thereby ensuring the corresponding design wavelength range and low group delay dispersion.

Fused silica has a lower coefficient of thermal expansion and extremely high thermal shock stability, making it particularly suitable for high-power femtosecond pulsed lasers and imaging applications. Note: The direction indicated by the arrow engraved on the side edge corresponds to the coated surface.

Ultrafast Mirror

  • Wavelength range from 340 nm to 1700 nm
  • Commonly used for optical path deflection
  • Suitable for high-power femtosecond pulsed laser and image fields

LBTEK Ultrafast Mirrors are commonly used for optical path deflection. Fused Silica has a lower Coefficient of Thermal Expansion and extremely high thermal vibration stability, making Ultrafast Mirrors particularly suitable for high-power femtosecond pulse lasers and imaging applications. Additionally, LBTEK Ultrafast Mirrors meet the requirement of a 45° incidence angle for the beam, with reflectance exceeding 99%.
