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. Nebular™ Technology won the Gold-Level 2020 Laser Focus World Innovators Award.

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.

Nebular™ Technology has an indistinguishable effect on transmitted beam profile relative to thin films while offering minimal loss and high laser-induced damage threshold (LIDT)
