  We present an approach for trapping cold atoms in a 2D optical trap array
generated with a novel 4f filtering scheme and custom transmission mask without
any active device. The approach can be used to generate arrays of bright or
dark traps, or both simultaneously with a single wavelength for forming
two-species traps. We demonstrate the design by creating a 2D array of 1225
dark trap sites, where single Cs atoms are loaded into regions of near-zero
intensity in an approximately Gaussian profile trap. Moreover, we demonstrate a
simple solution to the problem of out-of-focus trapped atoms, which occurs due
to the Talbot effect in periodic optical lattices. Using a high power yet low
cost spectrally and spatially broadband laser, out-of-focus interference is
mitigated, leading to near perfect removal of Talbot plane traps.
