Optical BK7 / Fused Silica  Optical Windows With Laser Protective Window

BK7 Windows

Description:

BK7 Windows are used in laser applications to separate different environments from one another. Laser Windows are ideal for protecting work areas or sensitive components by deflecting harmful laser beams. LaserLine Windows use substrates, coatings, or a combination of the two to transmit specific wavelengths or ranges of wavelengths. LaserLine Windows can also be used to optimize laser transmissions by transmitting only the wanted wavelengths

BK7 Windows are ideally suited for industrial and low power laser applications. The high tolerance design yields minimal beam distortion and scatter. Anti-reflection coatings provide <0.25% reflection at the coating\'s design wavelengths.

Competitive Advantage:

BK7 Windows  ,competitive price , good quality, delivery on time, providing perfect after-sales service, to provide customers with professional customized products of parameter. We will supply you with best solution.
