Product Family Description

  • R < 0.25% for 266nm, 355nm, 532nm or 1064nm
  • Low Auto-Fluorescence
  • Damage Thresholds up to 10 J/cm2 @ 10ns @ 1064nm

TECHSPEC® λ/20 High Power Laser Line Windows features a high efficiency, high damage threshold V-coating to maximize transmission at the design wavelength. Damage thresholds ranging from 2 - 10J/cm2 allow easy integration into most Nd:YAG laser systems. The coating is deposited on a precision excimer grade UV grade fused silica substrate for excellent thermal stability, low wavefront distortion, and ultra-low auto-fluorescence. TECHSPEC® λ/20 High Power Laser Line Windows are available in diameters ranging from 5 to 50mm.. For custom options or wedged versions, please contact our Sales Department.
