Product Family Description

  • Diffraction Limited at Designed Nd:YAG Laser Wavelengths
  • Laser Damage Designed Coatings on UV Fused Silica Substrates
  • Specified Slope Error to Guarantee Low Mid-Spatial Frequency Errors
  • High Precision Laser Grade Aspheric Lenses are also Available

TECHSPEC® Precision Laser Aspheric Lenses are designed to maximize performance in high power laser applications. Featuring diffraction limited performance at their designed wavelengths these aspheric lenses are available with high laser damage threshold coatings optimized at the most common Nd:YAG laser wavelengths. With a λ/2 aspheric surface figure and 0.35μm/mm slope error, TECHSPEC® Precision Laser Aspheric Lenses minimize the mid-spatial frequency (MSF) errors and are ideal for integration into demanding laser processing, cutting, and additive manufacturing applications. Featuring UV fused silica substrates, these aspheres are highly durable and resistant to thermal expansion.
