Parallel light illumination for objects several dozen meters away

Comparison of relative light intensity depending on distance between IBF series and normal light source

With an ordinary light source, the light is reduced in inverse proportion to the square of distance.

When the distance is doubled, for example, the light intensity is reduced to only one-quarter, which is not enough to illuminate objects at a distance.

However, the IBF series does not follow this formula, and is capable of illuminating far-away objects without a reduction in light over the distance as shown in the above graph.

Laser pointer replacement (visual use)

Unlike laser pointers, IBF illumination can be illuminated on the surface, improving visibility.

Use as a backlight for a silhouette that does not wrap around (dimension and shape measurement)

In the case of diffused light, the light wraps around the work and the silhouette cannot be accurately captured.

Irradiation with parallel light prevents wraparound and captures the silhouette accurately, enabling accurate measurement of dimensions.

By illuminating an object with a lens effect with parallel light, it can be prevented from entering the camera, the silhouette can be accurately captured, and accurate dimension measurement is possible.

Irradiate the edge to enhance the irradiated area (edge detection)

When illuminating parallel light to an edge of two irregular objects with some depths, it is possible to emphasize only that edge.
