Morphology

lensless = lens (transparent) = lens + less

The adjective is directly formed by adding the productive suffix '-less' meaning 'without' to the noun 'lens', yielding the straightforward meaning 'without a lens'.

Etymology

Lensless is made from lens and the ending -less, which means 'without', just like in hopeless or careless. So lensless literally means 'without a lens', which is why we use it for cameras or microscopes that do not use a lens.
