The LETO phase modulator is based on reflective LCOS microdisplays with 1920 x 1080 pixel resolution. With a pixel pitch of only 6.4 μm and small interpixel gaps of 0.2 μm the LETO SLM provides a high fill factor of 93% and thereby high light efficiency.

The LETO is also prepared to work in color-field-sequential (CFS) mode. For operation with color-switchable LASER the LED connector can be used to synchronize the light source with the device. 

The LETO series covers a version for the visible (420-650 nm), a version for version for the near IR (650 -1100 nm) and a fast version for Color Sequential (CFS) operation in the visible.
