Hello, welcome to Haian Hui Hong Optoelectronics site!
L color mirrors to change the amplitude and the effect of color is larger, can significantly improve the color temperature of the light source, lens color is dark blue.
Due to more daylight type film, color balancing 5500k, in light of 3200K. Images taken with the obvious partial red, orange. Therefore, with rising color temperature can make the mirror light color temperature increased significantly, to obtain the color balance of the photo.
Using fluorescent type reversal film in indoor iodine tungsten light irradiation, the captured color still life significantly redder (see figure a) and rose after the lens color temperature, color correction (see Figure b).

Has more than 30 years of rich experience and technology research and development capabilities, is committed to become the leading and promote the development of the international optical industry leader;
Cooperate with CCTV, has been adhering to the "continuously to meet customer demand, improve enterprise's social value, the pursuit of perfect design, perfect the self" business philosophy.
