Plan Optik AG is the leading manufacturer of structured wafers when it comes to technology. In sectors such as consumer electronics, automotive, aerospace, chemistry and pharmaceuticals these wafers are essential components used as active elements for numerous applications in MEMS technology. The wafers of glass, glass-silicon compounds or quartz are available in sizes up to 300 mm diameter. Wafers by Plan Optik provide high-precision surfaces in the ångström range (= ten millionths of a millimetre), which are achieved through the use of the MDF polishing process developed by the company. The wafers are available to minimum tolerances with application-specific structuring and complex material combinations. Plan Optik's extensive experience in the integration of optical, electronic or chemical functions within a wafer as the basis of MEMS applications has made the company the preferred partner of large international manufacturers. Based on Plan Optik's expert knowledge the wafers are developed in collaboration with customers such as OSRAM, Infineon, Motorola, Samsung, Honeywell and Bosch. Plan Optik develops and manufactures customer-specific wafers by integrating the necessary functions into the structure and material combination within the wafers. These wafers are subsequently separated into their individual elements, which in turn serve their purpose as an active element within the application. Plan Optik supplies international customers directly for mass production.
