• Protective Shield for Optical Systems
• Sizes from 50 mm to 134 mm
• Uncoated and Laser Line Coated Options Available
Laser Debris Shields, also referred to as laser cover slides or laser cover glass, are designed for use in laser
machining applications and can dramatically improve the longevity of more complex optical assemblies within
a system. These shields are constructed of durable fused silica for an optimal combination of transmission and
protection from harsh manufacturing environments. Laser Debris Shields are available either uncoated, in a
variety of Nd:YAG laser line Anti Reflective coatings that provide reflectivity of less than 0,25% per surface, or
with a NIR I Broadand coating with reflectivity of less than 0,5% per surface.
• Uncoated First Surface Provides Fresnel Reflection
• High Laser Damage Threshold Coating on One Surface
• 10-5 Surface Quality

• C-Axis Cut Sapphire to Eliminate Birefringence
• 10-5 Surface Quality and λ/10 TWFD
• Uncoated or IBS AR Coated for 1000 - 1100 nm
Laser Grade C-Axis Sapphire Windows are precision optical windows cut to the C-axis of sapphire to eliminate
the inherent birefringent properties of the material. C-axis sapphire, also referred to as C-plane sapphire or zero
degree sapphire, provides high transmission from the ultraviolet (UV) to the mid-infrared, excellent chemical
resistance, and high surface hardness second only to diamond. Featuring laser grade 10-5 surface quality and
λ/10 transmitted wavefront distortion (TWFD), these windows are ideal for use in laser applications or for integration
into laser systems. Laser Grade C-Axis Sapphire Windows are available uncoated or with an ion-beam
sputtered (IBS) antireflection (AR) coating for 1000 - 1100 nm, ideal for Nd:YAG, Yb:doped fiber, or Yb:YAG
laser applications. Standard imperial sizes facilitate drop-in replacement into existing laser systems; please
contact us if your application requires a Laser Grade C-Axis Sapphire Window with a custom size or coating.
