3.39 um Verifire Interferometer

The motorized turret switching between 1X and 2X zoom is a lifesaver during alignment—no more swapping lenses by hand. Fringes stayed rock-solid across the full 6-inch aperture, and the HeNe source warmed up fast. Exactly what I needed for mid-IR testing.

The 640 x 512 sensor gives crisp fringes even on tricky surfaces, and swapping between 1X and 2X zoom in the turret is genuinely seamless. Set-up took me an afternoon, but the 6" aperture handles large optics without breaking a sweat. I've used worse systems at twice the price.

The motorized turret switching between 1X and 2X is such a time saver when I'm checking different surface areas on the same optic. Alignment was dead simple to dial in, and the 6" aperture handles my larger flats without any edge falloff issues.
