Sensor Si Lens / Silicon infrared Lenses Laser Sanning 3μm - 12μm
Thermal Infrared Lens are used in a variety of infrared
applications operating in the 3- 12μm wavelength range, including
NIR imaging or IR spectroscopy. Silicon’s low density (2.329 g/cm3)
is ideal for use in weight-sensitive applications. Silicon features
a Knoop hardness of 1150, making Silicon Optical Components harder,
less brittle alternatives to comparable silicon Optical Components.
GIAI Optics features a wide variety of Silicon Optical Components,
including optical lenses, optical filters, or windows. Silicon
optical lenses are ideal for collimation or focusing applications
monochromatic light. These lenses are available in a range of sizes
or focal lengths for a wide variety of application needs. Silicon
lens kits are also available. Silicon optical filters, which are
integrated into IR applications such as FTIR spectroscopy, are used
to transmit or block a specific range of IR wavelengths. Silicon
windows are available uncoated or with a 3 - 5μm antireflection
Infrared (IR) Achromatic Lenses are ideal components for designers
and researchers working in the 3-5um 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.
