beam sampler

Ultra-thin
Extremely lightweight
Uncoated for beam sampling
Minimizes disperson and eliminates ghosting

Pellicle beam samplers are ultra-lightweight components that virtually eliminate multiple reflections commonly associated with thicker glass beam samplers. Pellicles are manufactured by stretching a 5 ?m thick polymer membrane over a flat metal frame. The extreme thinness eliminates secondary reflections by making them coincident with the original beam. Multiple wavelength versatility is an added benefit of an ultra-thin reflective membrane.
