Fiber Optic Backlights

Meiji Techno Backlights feature outstanding illumination uniformity and a glass bundle that will not melt when exposed to high energy or heat at the input.

Meiji Techno Backlights fit all fiber optic light sources sold by Meiji Techno, including:

• FL180 Series
• FL150 Series
• FT190 Series

This lighting method producing a sharp, high contrast silhouette of an object is known as backlighting. With machine vision inspection applications, the camera white balance is adjusted to record the illuminated plate correctly, so that any object placed in front of the backlight appears dark and a useful silhouette is created.

However, because light output is very diffused, backlights can also be used for highly specular specimens in transmitted or incident light microscopy. Meiji Techno carries three sizes of backlights with the following features:

• Intense, uniform output to insure consistency and optimal performance.
• The standard bundle length is 36 inches (914mm).
• Because the fibers are glass, the input can withstand the heat (and light energy) that can melt other plastic fiber products.
• Meiji Techno Backlights can also be used with most available strobe light sources.
• Fixture holes in the all aluminum, black anodized body are deisigned for easy mounting
• The stainless steel input adapter is swaged on stainless steel sheathing for extra durability and long life.
• Housing thickness is less than 1 inch (25mm).

Guidelines for Machine Vision

Use an active area just large enough to silhouette the product. If the backlit area is too large, diffused light from adjacent areas will create flare and blur the edge, making measurement of the silhouette difficult. If the backlight is too large, use an opaque mask to reduce flaring. If further refinement of the image is required, increase the distance of the mask and the product from the backlight. This has a "collimating" effect which should also improve image quality. It reduces the effective size of the backlight which can work either for you or against you.

Note: The standard diffuser plates are made of acrylic plastic so if your application involves temperatures above 70°C, let us know your requirement.
