OASLM
HOASYS Liquid Crystals optically addressable spatial light modulators (OASLM).
No preimposed pixelized structure permits to avoid diffraction losses.
Two models are available, OASLM-VIS and OASLM-NIR. VIS and NIR refer to the writing (addressing) wavelength: visible light (450 – 570 nm) for the OASLM-VIS, near infrared for the OASLM-NIR. The reading light to be modulated can be at a different wavelength, from 400 nm to 2 µm. The OASLM-NIR works in transmission or in reflection for reading light above 950 nm, and in reflection only below 950 nm.
HOASYS OASLMs are custom based solutions in order to address customer needs.

If you need to generate phase or intensity patterns, we recommend the OASLM-Kit.
The OASLM-Kit combines an OASLM with the LC-PROJ programmable light-addressing system and dedicated software, providing a complete solution for generating customizable optical patterns.
