Our TECHSPEC® Infrared (IR) Achromatic Lenses are ideal components for designers and researchers working in the 3-5μm spectral region. Designed to provide near diffraction-limited performance over their full spectral range, our lenses are ideal for applications in FTIR Spectroscopy, Thermal Imaging, and for use with tunable QCL Lasers. The lenses provide significantly improved performance versus comparable singlets, allowing designers in industrial, medical, scientific, and military applications to use the full dynamic range and quantum efficiency of their mid-wave sensors.
The doublets feature precision Germanium and Silicon lenses, expertly air-spaced and aligned within an anodized aluminum barrel. All lenses are coated for maximum energy throughput over the full 3-5μm spectral region. Prescription information available upon request. Please complete a Request for Prescription Form.
