Hoya 39 mm Cross Screen Glass filters have a surface that is etched with a fine grid pattern. Depending on the pattern, point light sources and reflections create multi-beam stars.
Hoya's Star 4 Cross Screen is designed so that a 4-point star is created from point light sources and reflections.
The effect is produced by a series of thin lines etched into the flat optical surface of a clear filter
Exciting and dazzling star effects generated from original point or reflected light sources with the added glitter and sparkle of these exclusive, natural looking asymmetrical designs and shapes
Great for water scenes, candle flames, street lights, and more

Hoya filters consistently provide even color all the way through the filter; All surfaces are ground and polished to specific thickness and tolerances
Even non-multi-coated Hoya filters have one layer of anti-reflective coating applied to each surface of the glass; Hoya's single layer coating decreases light reflection off the surface from approx. 9% to an average of 4-5%
