Measuring flatness optically

Monochromatic lights

Knight Optical adds to their portfolio a new range of low pressure sodium monochromatic light units, used for testing fringe patterns on the surface of optical flats (Newton’s rings).

Our monochromatic light units use a low pressure sodium light source which allows for very economic running costs and a long operating life.

The effective monochromatic wavelength is sodium 5896A, so λ/2 is approximately 0.3 microns.

We provide three types of Monochromatic light units, Standard, Enhanced and floor standing moonlight. Light weight and compact, these units can be easily transported from one area to another as needed.

Knight Optical (UK) Limited has been a global leader in the production and distribution of scientific optical components for 22 years. We are providers of optical solutions and optical components to worldwide companies within the scientific, defence, medical, pharmaceutical, opto-electronic industries.
