Product Family Description

  • Color-Corrected for 3-5μm or 8-12μm
  • Near Diffraction-Limited Focusing
  • Full Prescription Data Available

TECHSPEC® Infrared (IR) Achromatic Lenses are ideal components for designers and researchers working in the 3-5μm or 8-12µm spectral regions. Designed to provide near diffraction-limited performance over their full spectral range, these lenses are ideal for applications in FTIR Spectroscopy, Thermal Imaging, and for use with tunable QCL and other infrared lasers. The doublets feature precision optical grade crystalline, expertly air-spaced and aligned within an anodized aluminum barrel. All of these IR lenses are coated for maximum energy throughput over their specified spectral region. TECHSPEC® Infrared Achromatic Lenses provide significantly improved performance versus typical infrared singlets, allowing signers in industrial, medical, scientific, and defense applications to use the full dynamic range and quantum efficiency of their infrared sensors.

Note: Prescription information available upon request. Please complete a Request for Prescription Form.
