Product Family Description

  • λ/4 Surface Flatness
  • High Tolerance Design for Superior Performance
  • Excellent Transmission from UV to MWIR

TECHSPEC® Precision Sapphire Windows are ideal for use in demanding applications that require superior broadband transmission from 0.2 – 5.5μm, including imaging or spectroscopy. TECHSPEC Precision Sapphire Windows utilize a high tolerance design in addition to the innate characteristics of sapphire, which include a high dielectric constant, high thermal conductivity, extreme surface hardness, and resistance to many chemical acids and alkalis, to improve system performance. Additionally, due to sapphire’s structural strength, sapphire windows are thinner than comparable standard glass windows, minimizing absorption.
