What`s TAC Material? |
Triacetate cellulose (TAC) is the best optical
material with superior high luminous transmittance (L.T.).at present,TAC is used in most of
LCD ( Liquid Crystal Display ) as the protective
film for the polarized PVA film.So,there`re lost of TAC around us and such as the screen of calculators,cellphones, laptops,TVs and so on .
See ,we are using TAC everyday. |

| 什么是TAC 材料? |
TAC 的中文全称为三醋酸纤维素。
TAC 以溶剂铸膜加工成膜，至今是光穿透度最高的高分子材料之一。
目前，几乎所在 LCD（液晶屏，包括计算器荧幕以及电脑液晶屏等等）
都使用TAC作为PVA偏光膜的复合材料。正是因为TAC拥有优良的光学性能，表面硬度以及搞刮伤能力，同时TAC具优良好的防止PVA偏光膜收缩。 |
|
| Why Choose TAC? |
Besides TAC has superior optical quality ,
TAC has more performances as below:
Anti - scratch High rigidity of surface.
Anti - water lmbibe - high density.
Anti - shrink .
Stable conglutination with polarized PVA film.
|
| 为什么选择TAC？ |
|
TAC 除了有很高的光学质量外，还有很好的表现如下：
抗刮擦 - 高强度表面
搞水份吸收 - 高吸收密度
不易收缩
稳定的偏光PAV膜粘附能力

| How Does The Polarized Sunlens Work |
Daylight travels in waves oscillating in all directions of three-dimensional space .Polarized light also travels,but mostly moves in two dimensions:horizontally and vertically.Vertical light brings useful information to the human eye ,enabling us to see colors and contrasts,while horizontal light simply creates optical noise or glare Where light strikes a non-metallic surface such as water it often reflects primarily in a horizontal plane .
This creates a high concentration of glare which can be selectively blocked only by a good quality polarizing filter. |

| 偏光片工作原理 |
| 自然光（非偏极光），其实是由会朝特定方向震动的电磁波所组，而被反射或散射或散射的光线又通常偏爱某个特定方向，这也是为什么偏光太阳镜可以滤掉从车顶或水池反射来的阳光的缘故；自然光经过了偏光镜片的过滤后，就只能让一下方向的光经通过，也就是说偏光镜片能先将光线偏极化，只允许一个方向的光通过（可视光）。
偏光太阳眼镜就是利用这个特性来阻隔有害光线，因为太阳光无论是碰触到任何特体都会因自然反射或折射产生有害之眩光，偏光太阳眼镜就能吸收这些会造成刺眼及眼睛伤害的强光，所以很大程度上阻隔因散射，屈折，反射等各种因素所造成之刺眼的眩光，使人在强光下长期活动时，眼睛不易疲倦，达到真正保护的功能，而且能上看见的东西更清晰立体。 |
