Infra-red Optics

Infrared optics are manufactured from substrates and anti-reflection coatings that maximize performance for applications operating above 700nm. IR optics are common in applications including thermal imaging, night vision, spectroscopy, and FLIR (forward-looking IR) applications for imaging and sensing. 

Test requirements and materials for IR optics and optical systems demand that these components be tested at their functional wavelength. The wavelength may be matched from the near IR (NIR) for sensing applications out to 10.6 microns (LWIR) for measuring rough-ground surfaces, lithographic optics, etc.

 

4D Technology’s PhaseCam NIR and IR laser interferometers provide accurate surface and wavefront measurements of spherical and plano IR optics and systems, from 1.053 to 10.6 micron wavelengths. With acquisition times under 30 microseconds these instruments are insensitive to vibration and air turbulence, enabling use in difficult environments such as production floors, clean rooms and environmental testing chambers.

AccuFiz IR interferometers operate at wavelengths from 1.55 µm through 10.6 microns, for measuring polished or rough-ground optics and metal surfaces, concave, convex and afocal IR components, and IR telescopes and lens systems. Their ability to capture high slopes makes it possible to measure aspherical optics without the need for a holographic element.

Products for Infra-Red Optics

AccuFiz IR

AccuFiz Fizeau can be ordered in Shortwave IR, Midwave IR, or Longwave IR wavelengths. Fizeaus interferometers can measure concave and convex spherical optics in their functional wavelengths.

PhaseCam NIR or IR

4D PhaseCam Twyman-Green interferometers can be ordered in wavelengths of 1053 nm or 1064 nm —and some custom wavelengths. PhaseCam is the industry choice for measuring concave spherical optics, from several millimeters to tens of meters in diameter.

FizCam 2000NIR

With short coherence, FizCam 2000 makes instantaneous measurements in NIR wavelengths.
