摘要： A spectral reflectance in the entire visible wavelength range may be decreased to decrease inconveniences in an image such as flare or ghost. A non-reflective periodic layer including a large number of fine uneven periodic structure bodies is formed on a substrate, and a neutral density (“ND”) film is formed on the other surface of the substrate by vacuum deposition, to improve an anti-reflection function. Regarding a beam entering the ND filter, the MgF2 film of the formed ND film suppresses the spectral reflectance at the boundary of the atmosphere and the ND film and at the boundary of the ND film and the substrate. The non-reflective periodic layer decreases the reflectance at the boundary of the substrate and the atmosphere.

摘要： This invention decreases deformation of a plastic substrate caused by thermal expansion and contraction in an evaporation process of forming a multi-layered film of an ND filter, thus arising of wrinkles is prevented. The plastic substrate serving as the base of the ND filter is made of a polyimide-based plastic material having a glass transition temperature of 200° C. or more, and has a total transmittance of light of 90% or more and has a haze factor, which represents the haze of 0.5% or less. As the multi-layered film, Al2O3 films for reduction of the reflectance and TiOx films for reduction of the transmittance are alternately formed on the substrate. An MgF2 film made of a low-refraction material is formed as the uppermost layer to further reduce the reflection. In the evaporation process, even when the temperature of the plastic substrate reaches almost 200° C., the sufficiently high glass transition temperature of the plastic material can suppress arising of wrinkles on that portion of the plastic substrate where the multi-layered film is formed.
摘要翻译：本发明减少了在形成ND滤光片的多层膜的蒸发过程中由热膨胀和收缩引起的塑料基板的变形，从而防止出现褶皱。作为ND滤光片的基材的塑料基板由玻璃化转变温度为200℃以上的聚酰亚胺系塑料制成，光的总透过率为90％以上，具有雾度系数，其代表雾度为0.5％以下。作为多层膜，用于还原反射率和TiO 2膜的用于降低透射率的Al 2 O 3膜交替形成在基板上。形成由低折射材料制成的MgF 2膜作为最上层，以进一步减少反射。在蒸发过程中，即使当塑料基板的温度达到近200℃时，塑料材料的足够高的玻璃化转变温度也可以抑制形成多层膜的塑料基板部分的皱纹。

摘要： The oscillation element according to the present invention includes a torsion bar mounted on a base, and an oscillating member having a light reflection surface for reflecting light from a light source, which is fixed on the torsion bar protruding from the base. The oscillating member oscillates about a longitudinal axis of the torsion bar with an elastic deformation of the torsion bar, thereby deflecting the light that reflects at the light reflection surface in a direction intersecting the longitudinal axis. The oscillating member has two plates that are joined together so as to sandwich the torsion bar. On joining surfaces of the plates are provided with grooves for receiving the torsion bar, respectively. The plates have a symmetrical shape that the longitudinal axis serves as the axis of symmetry.
