Laser protection windows

Good resolutions - for a long life

With our laser protection windows, you are opting for a high-quality and affordable solution for the optics of your lasers.

The anti-reflective special glass acts like a protective shield in front of the optics: sparks, splashes and scratches no longer stand a chance.

Available in all common glass thicknesses, diameters or wavelengths, you will receive a custom-made product according to your individual specifications. And with that, a longer lifespan for your laser - plus longer quality in series!

 

 

Standard specification for laser protection windows

 

  • Standard substrate: Fused Silica (for lasers with higher output power)
  • Standard tolerances: ر0.1mm or +0/-2.0mm
  • Thickness: ±0.1mm or +0/-0.2mm
  • Edges grinded with facette                          (f.e. 0.3mmx45°)
  • Both sides mechanically polished λ4-λ6
  • Scratch/dig 60/40
  • Typical Standard Coatings: @1064nm T≥99.5%, @633nm T≥99.5% or broad band coating: for example @900-1080nm T≥99.5%
  • smudge-proof and scratch-resistant, adhesive peeling test, cleaning with alcohol mixture in a dust-free chamber, ultrasonic cleaning

Product features / typical applications

 

  • Single layer - AR (advantageous for materials with high refractive index)
  • Narrow-band AR coatings (e.g. for V-type single laser wavelength)
  • Broadband AR coatings
  • Multispectral AR coatings
  • Antireflective sight glass window to protect high-quality laser optics from splashing material
  • Antireflective laser scanner window

Optical antireflection-Coatings

„Antireflective coating enhances performance!“
 
Each beam of light generates a back reflection during the transition from one into another medium. Antireflective coatings are used to minimize effects like loss of power and the appearance of dangerous hot spots caused by the back reflection.

Antireflective coatings (short AR-coating) are used in a variety in optics as they reduce the reflection of  glass surfaces. The increased light transmission and a reduction of aberrations are the main advantages.

The following specification is necessary for a quotation

  • Required wavelength range
  • Substrate material (Fused Silica, BK7, Borosilicate glass 3.3, Float glass, Sapphire, and more)
  • Dimension tolerances
  • Transmission output and/or reflection
  • Angle of incidence in degrees
  • Laser power density in W/cm² (cw)
  • Energy density in J/cm² (pulsed laser)

Please feel free to contact us, if your need laser disc is not stated in the list and let us have your specification. (Diameter, coating and so on), so that we can arrange an individual offer for you.
