2.What is a 6-Line star filter, cross screen filter?
A 6-line star filter also called a 6-point star filter, it is an optical lens filter with a finely etched surface pattern, and create a six-pointed starburst effect from bright point light sources.
3.What is typical application for negative 6-line star filters？
4.What is key parameter when choose for right Star filters?
When selecting Star filters, the number of points (Lines) will be one of key parameter to be designated, with a line density (groove frequency) determines the sharpness and length of the star rays.
Shenzhen Hengda Liyuan Optoelectronics introduced advanced optical technology that apply depositing nanomaterials through ion-assisted evaporation onto a multilayer hard film in a high vacuum environment which coating layer is firm and has good tightness, and small bandwidth drift. Liyuan optoelectronics have been focus on optical coating for more than 17 years and offer one-stop optical filters solution including Narrow Bandpass Fitlers, IR cut-off Filters, Longpass & Short Filters,Notch Filters, ND filters, Star filters and Optical sapphire block.
