    Laser Windows

    Laser Optics

    Laser Windows are used to provide a high degree of transmission of specified wavelengths for use in laser applications or safety needs. Laser Windows may be designed for either laser transmission or laser safety purposes. In safety applications, Laser Windows are designed to provide safe, observable surface through which to view a laser or laser system. Laser Windows may also be used to isolate a laser beam, reflecting or absorbing all other wavelengths. Several varieties of Laser Windows are available for both laser transmission or laser blocking applications.

    Edmund Optics offers a wide range of Laser Windows suited for many laser transmission or laser safety needs. Laser Line Windows provide exceptional transmission of desired wavelengths while effectively reflecting unwanted wavelengths. High power versions of Laser Line Windows are also available for higher energy laser applications where higher damage thresholds are needed. Acrylic Laser Windows are ideal for laser applications that use Nd:YAG, CO2, KTP or Argon-Ion laser sources. Acrylic Laser Windows may be easily cut to fit into any shape required. Laser Speckle Reducers are also available for reducing speckle noise in laser systems.
