√Ar antireflection film: reduce the surface reflection light of lens, increase the antireflection film of transmitted light.
√UV / IR cut-off filter: used to remove unnecessary ultraviolet and infrared rays.
√Hard ar film: antireflective film with high visibility and hardness.
√Polarizing element: polarizing separation (PBS).
√Dichroic mirror: used for color decomposition and synthesis.
√Laser mirror: high performance mirror that changes the direction of light.
√Photocatalyst: the use of light to decompose organic films.
