LETO Phase Only Spatial Light Modulator (Reflective)
The LETO phase modulator is based on a reflective LCOS microdisplay with full HD (1920 x 1080 pixel ) resolution. With a pixel pitch of only 6.4 μm and a small interpixel gap of 0.2 μm the LETO SLM provides a high fill factor of 93% and thereby a high light efficiency.
The LETO Spatial Light Modulator is usable for the 400-1100 nm range and the modulator provides a phase shift of 2 π up to 850 nm. The device is delivered with a linear 256-level phase response for the specified user wavelength. The adaptation of the device settings for different operating wavelengths to a linear 2 π phase response can be done by straight forward gamma correction using the supplied calibration software.
The LETO Spatial Light Modulator offers a reflectivity of ~ 75%. Due to the optimized design of the LCOS microdisplay the LETO SLM shows low cross talk between the pixels resulting in high effective spatial resolution. The device offers diffraction efficiencies of more than 80% (16 level blazed grating) which leads to a total light efficiency of ~ 60%.
