Yutai Optics’ 10nm filters are ideal for chemical, environmental, or elemental analysis. Hard coated filters offer maximum performance with exceptional durability. Traditionally coated evaporated filters are cost-sensitive alternatives. Bandpass Filters are angular sensitive, so care should be taken when mounting or integrating into an optical system. For convenience, many of our filters are also available in kits.
