Polarising Optics
A strong emphasis on polarising optics means that Optisource are an excellent choice for waveplates, polarisers and rotators. Zero-order waveplates are available as an optically contacted, air-spaced, or glued assembly with ring mounting option. Low-order waveplates are available as an alternative to multipleorder waveplates when higher retardation stability is required. |
