What is Direct Flat Prizm Light?
Similar to the VDF.
Because of the prism sheet design, light is strongly irradiated in the vertical direction.
This design is suitable for projects with short exposure time.
The high directivi-ty of the prism sheet reduces the light rotation on the sides of curved surfaces, making it easy to capture edges in high contrast.
The larger light emitting area is compatible with lenses with longer focal lengths.
