SPOT TO LINE CONVERTERS 3601
Conversion of an optical path from a spot to a line is highly desirable in many scanning applications. It allows a photo detector with a round or square active area to become essentially a long linear array, or an inexpensive projector bulb to illuminate the entire width or a document or web. They are also used frequently to "pick-up" scattered or reflecting light from a laser and rotating mirror combination. Spot to line converters are produced in a wide variety of sizes and shapes, with line lengths of 125" or less up to lines nearly 2 feet long.

MACHINE VISION BACK LIGHTS 3602
The machine vision lighting method which provides a sharp high contrast silhouette of an object is referred as backlighting. Backlighting is used when the surface features of an object are not critical and contrast is needed to make it appear dark against a bright background. Backlighting is not only used in machine vision, it is also used in microscopy. Other possible applications, among many, for backlighting include, glass inspection, edge detection, filmstrip viewing, and electronic device lead location.

MACHINE VISION LIGHT LINES 3603
The lighting method which provides a line output configuration from a round light source is referred to as a line light. Fiber optic line lights are used in machine vision systems, angled lighting for robotics, inspection, metrology and line scan camera web applications. Using a fiber optic light line design with a quartz-halogen source provides an efficient means of distributing high levels of cold light to remote locations. They are easily interfaced and effective when a strobe light source is used.

Fiber Optic Ring Lights 3604
Ring Lights provide 360° of high intensity, shadow free, uniform, cold illumination. The units a housed in black anodized aluminum with a choice of PCV covered metal or stainless steel metal sheathing. ESD compliant ring lights are also available

Fiber Optic Light Guides 3605
Offers a variety of light guides that use high output 0.66 N.A. glass fiber to provide cool, uniform illumination. The fibers are housed in PVC covered mono coil sheathing with crimped stainless steel terminations. The following configurations are available:
A) Single Glass with PVC sheathing and straight end tip
B) Single Glass with PVC sheathing and right angle distal end tip
C) Single Glass with PVC sheathing and threaded distal end tip.
D) Single Glass PVC metal hose sheathing and straight end tip.
E) Dual Glass Light Guide with PVC sheathing and straight end tip

Fiber Ring Lights (Special) 3606
Streamlined system provides uniform, interference-free illumination over a wide range and distance, enabling user to match light output to applications instantly. Light output is brilliant and cool. Shadows are virtually eliminated. Adjusts instantly to change contrast. Eliminates glare without altering microscope optics. Rotating disk uniformly directs 8 light spots to single convergence point. Operating distance is 0-12" (0-24" ). Designed for situations where size or weight are factors. Competitively priced. 18" inch gooseneck. The R-90 is a streamlined eight point adjustable ring light with a slimmer diameter and non- reflective black anodized exterior housing. This eliminates all visual disturbances and allows greater freedom of motion for stereo microscope users. The new system's light output is brilliant and cool, and perfectly balanced. These are the highly polished end optical glass fibers. The new R-90 is also fully adjustable, making the system effective over the full 360º observation, and is eminently repeatable. Users can instantly vary the light convergence point from 0º to 90º with a turn of the adjustable thumb wheel. With its rugged, black anodized aluminum shell and ability to function in temperatures ranging from -40º to +600º, the R-90 is designed for the tough environments that scientists and researchers work in, the world over. The system is competitively priced.
