LCOS-based spatial light modulator delivers λ/40 flatness

January 26, 2017 // By Julien Happich
Based on an LCOS (Liquid Crystal on Silicon) device, Santec's SLM-100 spatial light modulator boasts a super-flatness of λ/40 at 633nm, using wavefront correction technology.

The SLM’s advanced high resolution of 10-bits (1024 gray level) is applied to compensate for the intrinsic spatial optical distortion and aberration in the LCOS device using a LUT (Look-up-Table). The wavefront correction technology is available for several SLM-100 models in optional visible wavelength. Super-flatness is a very important feature in various industrial applications such as astrophysics, precision holography and laser processing to achieve ideal optical performance on the image plane.
