Features
- Fly eye lenses are ***d in projectors, semiconductor manufacturing equipment, etc., to produce light with uniform brightness.
- Using a pair of fly-eye lenses allows you to illuminate a rectangular intensity distribution even when the light source is highly diff***, such as a lamp.
- Available in 2 types: 7×9 divisions with a focal length of 42.07 mm and 10×13 divisions with a focal length of 38.24 mm.
- With an anti-reflection film coat, incident light can be ***d for lighting with almost no loss of light.
- By using the press molding technology of glass lenses, both high performance and low cost have been realized.
- * Image forming lens is not included in the specification. Fly ray lenses are sold one by one.
- * When ***d with a highly coherent laser, noise may be generated in the intensity distribution due to diffraction by the boundary line of the lens.
