CHATSWORTH, Calif., March 25, 2008 -- Graham Optical Systems said its new line of 4-in.- and 6-in.-aperture infrared interferometers are affordable and include the 4-in. model 339ir, a phase-shifting Fizeau operating at 3.39 µm.
Graham Optical's 4-in. model 339ir, a phase-shifting Fizeau operating at 3.39 µm.
The 339ir uses a helium-neon laser operating at a wavelength of 3.39-µm to produce a high contrast, speckle-free image. It is also available in a 6-in. version.
Other models are available at 1.06 µm or 1.55 µm, the company said, and all models are offered in dual-wavelength versions which permit switching from infrared to visible wavelength (632.8 nm). Both infrared and visible beams are coaxial, greatly simplifying alignment of the test piece, and custom versions are available.
With a small footprint and solid construction, the interferometers exhibit the highest contrast fringes available with excellent repeatability and reproducibility, Graham Optical said. The turnkey instruments are provided with computer and phase software.
