• Fabry-Perot etalons are a combination of parallel plates or a combination of precision parallel plates, a wedge substrate, and spacers.
• High-accuracy etalons for use in various fields can be prepared from a high-flatness substrate and highly parallel spacer with your desirable reflection coatings.
• These products are produced in an integrated Sigma Koki production line, from polishing of raw materials to thin film coating by deposition.

注意

• When no external tolerances are specified, Sigma Koki's standard tolerances apply.
• The surface flatness is the reflected wavefront distortion of the surface before coating.
• Be sure to wear laser safety goggles when checking optical path and adjusting optical axis.
