Holoeye Photonics AG's new HEO 1080 P phase-only modulator is based on a reflective LCoS (liquid crystal on silicon) microdisplay with full WUXGA/HDTV resolution (1920 x 1080 pixels). Due to the electrically controlled birefringence display mode, the phase panels provide a pure phase shift of 2 Pi up to 1064 nm. Currently there are two panel versions available optimized for 420–810 nm and for 800–1100 nm. All optical phase functions (gratings, phase masks, holograms, etc.) are addressed by a DVI graphics card, which can be implemented in a standard PC using the SLM device simply as an external monitor. A graphical user interface enables the user to adapt the modulation performance to an actual task and laser wavelength. With a pixel pitch of only 8 µm, high-definition TV resolution, a high light efficiency (due to the reflective structure of the microdisplay) and an image refresh frame rate of 60 HZ via DVI, the HEO 1080 P phase-only modulator is the right solution for a wide range of applications, ranging from wavefront correction, optical tweezers, optical metrology, interferometry, lithography, holography to all other phase-shifting applications.
