This application relates generally to a method and apparatus to deposit particles onto one or more coupons, and harvest particles from one or more coupons, which may beneficially provide a more uniform or localized distribution of particles over a specified area on each coupon. The application relates to a method and apparatus for depositing particles onto one or more coupons using a sieve. The application also relates to a method and apparatus for depositing particles onto one or more coupons using a dust storm. The particle loadings achieved on each coupon or across an individual coupon may be substantially uniform. The application further relates to a laser-based method and apparatus for transferring particles deposited at localized points on a source coupon to a different substrate for further use.
