-
The DF241 is characterized as a Small Low Angle Dark Field ring light.
-
Precisely aimed LEDs provide a very low angle of incidence, radial illumination pattern.
-
A scratch on a sheet of glass is a good example of a defect that can be detected with a low-angle dark field illuminator.
-
With a light intensity of 24kLux at a working distance of ½” (12.5mm), the DF241 is perfect for imaging problems limited to a small field of view.
-
A 25mm field of view is standard with an optional field of view of 35mm.
-
Available in a range of wavelengths from UV to IR.
-
*Engineered to provide comparable optical characteristics to our previous RL1360.

Luna’s Fiber Optic Switches (FOS) 008 and 036 are cost-effective 1xN optical switches with impressive performance and flexibility. With low insertion loss, low wavelength dependent loss and flexible port count, manufacturers can perform high-port count optical test and measurement including DWDM channel testing and multiplexed optical sensing with reduced time and cost. The FOS can be integrated with Luna’s other industry-leading test and measurement products to enable scalable integrated testing for the manufacturing floor. Luna’s FOS is the only switch certified and tested to be fully specification compatible with our award-winning line of fiber test products. Not all fiber switches are the same. Rely on our experience.
APPLICATIONS
Multi-port DWDM Component Testing
Luna’s’ Fiber Optic Switches provide a cost-effective way to multiplex fiber optic testing requirements. An example where multiplexed testing can save both time and expense is in manufacturing test of modern, multichannel dense wavelength division multiplexed (DWDM) fiber components and systems. Typical components, found in a DWDM architecture, include both static and dynamically controlled multi-channel filters (AWGs, ROADMS, etc.). As bandwidth increases, so do the testing requirements for these backbone components. Typical testing requirements for DWDM components include Insertion Loss, Polarization Dependant Loss, Chromatic Dispersion, Group Delay Ripple and Polarization Mode Dispersion, which are all measured with high wavelength resolution (< 10pm) over the entire communications band (e.g. 1525 nm – 1565 nm). For multi-port components, this may lead to hours of testing for a single component.
Luna’s solution is simple: Integrate our Optical Vector Analyzer with the FOS 036 using our Software Developer Kit for easy introduction of multiport testing into any environment. Stable, configurable and fast, this combination enables testing a high-port count DWDM for all parameters in a matter of minutes.
Fast and Accurate Fiber SKEW Measurement
Skew measurements can now be made on multimode and/or singlemode fiber cables and ribbons using Luna’s user-friendly Software Developer Kit in conjunction with a Luna Optical Backscatter Reflectometer and the Luna Fiber Optic Switch. The skew measurement capability relies on the OBR’s ability to measure minute reflections (< -135 dB) out to 2 kilometers with zero dead zone and industry-leading sub-millimeter spatial resolution.
Skew is determined by making a single-ended time-of-flight measurement of each fiber in a cable strand and computing the path differential, which is then graphically displayed to the user. With the single click of a button, this can all be achieved in less than one minute. Additionally, with the same measurement, the user can apply OBR software tools to characterize the dispersion of each fiber in the cable strand, and reduce overall test time and the duplication of equipment.
