Laser Line Windows with Nebular™ Technology
• Precision Fused Silica Windows with Nebular™ Nano-Structured Anti-Reflective Surfaces
• Greater than 99.8% Transmission at Popular Nd:YAG Laser Wavelengths
• High Power Alternative to Traditional Anti-Reflective Coatings
TECHSPEC® Laser Line Windows with Nebular™ Technology are designed to be used in demanding laser applications
requiring high transmission and high laser damage thresholds. The absence of dissimilar materials
such as thin film coatings eliminates stress, absorption, and heating at the surface of the window, reducing
thermal lensing and increasing the laser-induced damage threshold. 355, 532, and 1064nm versions are available
with specified high transmission, guaranteeing minimal scatter loss from the sub-wavelength structures at
the design wavelength. TECHSPEC® Laser Line Windows with Nebular™ Technology are available in common
imperial sizes and are ideal for integration in laser optics assemblies.
NOTE: While the nano-structured surfaces can withstand high laser fluences and powers and have excellent
UV durability, the surfaces are sensitive to mechanical contact. Do not touch surfaces and do not wipe clean.

IBS Laser Line Windows
• IBS Coated for Minimal Absorption and Scatter
• <0.1% Reflectivity at Nd:YAG Laser Lines
• Guaranteed Laser Damage Thresholds at Design Wavelength
TECHSPEC® IBS Laser Line Windows feature an ion beam sputtering (IBS) anti-reflection coating that provides
<0.1% reflectivity at their design wavelength with minimal losses due to absorption or scatter. The IBS coating
process produces dense, homogeneous coating layers that are environmentally stable and insensitive to
temperature and humidity changes, enabling these windows to be used in harsh environments. TECHSPEC®
IBS Laser Line Windows are available in standard imperial sizes with designs for the Nd:YAG laser wavelengths
of 355nm, 532nm, and 1064nm. In-house manufacturing enables Edmund Optics to provide custom sizes and
designs in the wavelength range 343nm to 1600nm.
