陷波片的特点：可定制单谱线陷波片或者多谱线，

可选择高反射>99.9%或者OD 6.阻带线宽，可根据需求，做到1nm一下。

的特点：
Available as single-line or multi-line notch
Wavelength position of notch or notches can be preset to user-specified values
Can be designed for both normal incidence andnon-normal incidence applications
Either high reflectance （> 99.9%） within the notch or deepblocking, up to OD 6 achievable
Suitable for use over wide operating temperature range（ - 200°C to + 200°C）
Can be constructed with minimal wavefront distortion to be suitable for imaging applications
Can be fabricated in a wide variety of shapes and sizes
Offer extremely robust environmental durability characteristics
Custom Rugate Notch Filters can presently be fabricated within the spectral region from the UV to the near-IR
