產品概覽

  • 偏振敏感性低
  • 非常適用於直列式組態

穿透光柵專為以特定角度對入射光執行散射而設計。在入射角增大或溝槽間距減小時,色散也隨之增大。稀疏的溝槽間距可保持高效率,而細密的溝槽間距可降低長波長的穿透率,導致效率很低。

Transmission Gratings offer low polarization sensitivity as opposed to reflection gratings because incident light is not reflected by a mirror coating such as aluminum. Since light is transmitted through the grating, transmission gratings can be used in compact, in-line configurations. They are ideal for use in monochromators and spectrometers.

Transmission Gratings are manufactured in the same way as ruled reflection gratings in which a replica of a master grating is created by duplicating its grooved surface with a thin, vacuum deposition-coated layer, except they have no reflective overcoat. Uncoated transmission gratings provide high efficiency over a long wavelength range while Anti-Reflection (AR) coated gratings increase performance at a specific wavelength. AR coated versions are available upon request; please contact our Applications Engineering Department.

Handling Gratings: Gratings require special handling, making them prone to fingerprints and aerosols. Gratings should only be handled by the edges. Before attempting to clean a grating, please contact us.
