The LETO phase modulator models are based on reflective LCOS microdisplays with 1920 x 1080 pixel resolution and 6.4 μm pixel pitch.
The LETO series offers 3 different versions and are optimized for wavelength ranges in the visible (420-650 nm), a version for the near IR (650 -1100 nm) and a fast (180 Hz) version for Color Field Sequential (CFS) operation in the visible with color- adjustable RGB LASER (Note: different pulse-code programming / calibration is necessary).
The LETO phase only spatial light modulator devices can be used like an external monitor using the standard HDMI interface of the graphics card. No additional software or special hardware is needed to operate the SLM.
| Device | λ Range | Maximum Phase | Average Refl. |
