Proline 80 Series Gains CE Approval

Tue, 28 Mar 2017 23:24:00 GMT

We are pleased to announce that the Proline 80 series of LED Ring lights has been granted CE approval.
CE = C onformité E uropéene.

For those not familiar with CE Marking, it is the a manufacturer’s declaration that the product complies with the essential requirements of the relevant European health, safety and environmental protection legislation, in practice by many of the so-called Product Directives.
Products acquiring this approval are ensured free movement of the product within the EFTA & European Union (EU) single market and the CE Marking on a product permits the withdrawal of the non-conforming products by EEA customs and enforcement/vigilance authorities.

The first page of CE is shown below. To view the full document please sign up.

Don’t Be Casual in Your Selection of Borosilicate Fibers for Precision Lighting Systems

Mon, 07 Mar 2016 04:57:00 GMT

Basing your optical component selections on single properties like numerical aperture (N.A.) or fiber diameter can backfire on you.

However, you can reduce the probability of potential problems by reviewing real-life data revealing the impact of varied fiber-optic formulations on the transmission of broad-spectrum light. After assessing this post on fiber properties and potential pitfalls in their selection, your optical systems engineers will be equipped to make more informed decisions.

Test Methodology

A number of fiber-optic cables were prepared: all had common length, common bundle diameter, common sheathing, and common ferrules.

Our testing looked at transmission (flux), beam angle, and selective absorption; the method of polishing fiber, index of refraction of the fiber, and the fiber diameters was varied. All fiber bundles were powered using a 250-watt 4-channel LED fiber-optic illuminator manufactured by Techniquip.

Flux was collected using a Labsphere integrating sphere. All other data was collected by a spectrometer positioned 250 mm from the fiber exit face.

Two series of Fiber Optic Transmission Testing Completed 2.23.16 tests were conducted. In the first the cables were powered directly from the LED illuminator. In the second series of tests the output of the LED illuminator was sent through a preconditioning patch cable to reduce NA. This was done so that better estimates of the pure transmission losses could be determined.

Series 1 Test Data

Series 2 Test Data

Spectral Composition of Light From Source and After Exiting Bundles of Varying N.A.

Results with Definitive Implications

The data showed a huge difference in flux between 0.22 N.A. fiber and the more common 0.55 / 0.66 N.A. fibers.

For a system requiring low angles, there are likely more effective ways to transmit light and block stray light than using 0.22 N.A. fibers. Contact TechniQuip for more information on better techniques and equipment for achieving the best results.

The data shows a dramatic shift in Corrected Color Temperature (CCT) and drop in Color Rendering Index (CRI) between the source and the light exiting all the various fibers. You can see here that, for a desired CCT / CRI outcome, looking at the source properties is not sufficient to ensure a good design.

The data also showed that relative to other factors, the impact of polishing method and fiber diameters was negligible.

The above testing helped us complete the development of a high-power OEM darkfield lighting system for semiconductor inspection applications using a quad‐LED illuminator and borosilicate fiber optics.
