產品系列說明

  • 穿透效率超過85%
  • 提供圓形與橢圓形擴散輸出
  • 非常適用於可見光及近紅外應用
  • UV Holographic Diffusers Also Available

全像擴散片用於控制照明的擴散區域,並針對白熾燈、LED、弧光燈及其他光源將光線的穿透效率提升至90%以上。標準磨砂玻璃乳白色玻璃將產生擴散照明,但是漫射光區域通常超出系統的需求。傳統擴散片所關聯的這一過度照明特性會降低效率,由於需要功率更高的照明光源、透鏡以及可能的濾光片,因此通常導致成本升高。請務必注意:平行輸入光束的擴散角度已指定,角度發散性將視不同的入射角而有所不同。

Unlike many holographic elements, these specific polycarbonate components can be used throughout the visible and near-infrared. Available individually, as umounted sheets, or in sets of four filters. Holographic Diffusers can be cleaned with a de-ionized water rinse, followed by a forced air drying. Wipe gently with lens tissue soaked with methanol, followed with a forced clean air or nitrogen drying. Holographic Diffusers are resistant to methanol and methylene chloride.

Note: Matte surface should face the light source. To clean holographic diffusers, dampen a lint free cloth wipe with methanol and gently wipe the entire diffuser surface in a gentle, circular pattern. Immediately and carefully blow off the clean diffuser area with dry compressed air. Caution: cleaning may cause a change in the optical performance of the diffuser.
