Flat optical-part requirements
For a proposed K9 window or substrate, define the working wavelength, clear aperture, thickness, edge condition and required surface quality. TTV, flatness, roughness and scratch-dig control different features and should be specified separately.
K9 processing experience
We have processed K9 optical glass specified by a customer. For new work, confirm the complete grade and source documents so the drawing refers to the intended glass.
Drawing review
Send the part drawing, quantity, functional faces and acceptance method. The requested cutting, surface and inspection route can then be evaluated for this component.
