The GAEA-2 phase only Spatial Light Modulator (SLM) consists of a driver unit with standard digital video interface (HDMI) and a phase only LCOS (Liquid Crystal on Silicon) microdisplay with a 10 megapixel (4K) resolution of 4094 x 2464 pixels, and 3.74 µm pixel pitch leading to an active area of 0.7" as measured diagonally. The very small pixel size of the GAEA SLM display ensures high diffraction angles.
The GAEA-2 SLM is a plug & play device and can be addressed with phase functions via standard graphics cards as an extended monitor. It offers 8-bit grey level patterns (= 8-bit phase levels) providing the graphics card is able to deliver an uncompressed output at 3840 x 2160 pixel resolution. Addressing can easily be done using the supplied Application Software or other standard image viewer software.
The very small pixel size of the GAEA-2 SLM display enables high diffraction angles of up to 12°.
HOLOEYE offers three versions of GAEA optimised for the use in different wavelength ranges: VIS for 420 to 650 nm, NIR for 650 to 1100 nm, and TELCO for 1400 to 1700 nm.
