Precision Optics SLI 202  ALI 202 In-production quality assurance

A small set of high-quality transmission spheres allows the measurement of a broad range of convex and concave spherical surfaces. The compact workshop interferometers enable placement on the production floor, providing ready access to the optician and increased productivity. The vertical vibration-isolated design requires minimum floor space. The full housing protects the instrument in less-than-ideal environments. A live monitor display of the fringe patterns makes the alignment easy. The phase measuring feature results in an accurate wave front map which you can further study by the user-friendly...
