4" Verifire Interferometer MST+

The 1.4k x 1.4k camera gives crisp fringe patterns, and the fixed 1x magnification is exactly what I needed for my 4" optics. Setup was straightforward, and the ring accessory makes alignment a breeze. Very impressed with the coherent imaging performance right out of the box.

Finally got this set up with the 1.4k camera and the ring illumination is much more even than my old system; the coherent imaging really helps see fringes clearly.

The 1.4k camera captures incredibly sharp interferograms right out of the box, and the coherent imaging system eliminates the ghosting I used to fight with my old setup. Setting up the ring light was a breeze, and the fixed 1x magnification is perfect for my standard 4-inch testing.
