What is a CPL filter and how is it customized in factories?
A CPL (Circular Polarizing Lens) filter, such as those by Yinben, is used in photography to reduce reflections and enhance color saturation. It's manufactured with customized coatings and precise thickness adjustments to ensure optimal optical performance.
In factories, Yinben customizes CPL filters by ensuring the polarization film's alignment is precise, which is critical for maximum polarization effect. This involves using automated machines for perfect film placement and applying vapor deposition for uniform coatings. The thickness and refractive index must be carefully controlled; typical values might range from 100 to 120 microns for thickness and around 1.5 for the refractive index.
