IS it necessary to place a lens after SLM?

a lens shouldn´t be necessary at all. What you are sending to the SLM should be a phase plate encoding Bessel beam you want.

hope it helpful for you

IS it necessary to place a lens after SLM?I work with transmissive spatial light modulators.

IS it necessary to place a lens after SLM?I work with transmissive spatial light modulators.if I dont place a lens after SLM I see a picture that I addressed to an SLM.
