Lamtech Instrument
Optical flatness measurement is reliable to the micron range accuracy. Typically used when measuring a wide range of accuracy. Typically used when measuring a wide range of parts, specifically 11+ inches in diameter
Optical Flats
For flatness control in combination with our monochromotic inspection lights.

Monochromatic Inspection Light
The flatness of workpieces is measured with the interference tester. The lamp generates monochromatic light and thus permits the interference fringes to be seen using a precise optical flat. The distance from one so-called “light band” to the next is around 0.3 microns.
