2019109 — While infrared and ultraviolet light are invisible to the human eye, there are still plenty of things people can see.

Perhaps you have seen a display of polarized sunglasses in a store. You can quickly test to see if the glasses are really polarized by looking through the lenses of two glasses and rotating one pair by 90°. If both pairs of glasses are polarized, the lenses will appear to go black. Why is that?

The 4-watt bulbs used by some FraudFighter products are manufactured at our facility with the highest quality standards. As with all replacement parts, it is important to select a part with the same high quality as the original. For this reason, we recommend that you buy your replacement 4-watt tubes from FraudFighter.

Using hook & loop materials and stick-on drawing pieces, students can develop an understanding of the following light reflection and refraction concepts.

Replacement bulbs for the UV-16 and the POS-15 must have part number T5UV16-POS15. The use of any bulb part number other than T5UV16-POS15, including the UVF861 bulbs sourced from unauthorized dealers, would invalidate the warranty on your UV-16 or POS-15 and could be hazardous.

Part #: UVF-461Replacement bulb for the UV-4 and the HH-4. This bulb can also be used as a replacement for POS-15 models produced before 2005 as well as the discountinued UV-8 model.

These UV LED light bars will induce growth characteristics in your plants during the fruit and flower grow stages.

Now that the case is decided, FraudFighter is free to use the UVF861 mark, but is concerned about confusion in the marketplace over which part to use. Since 2012, the FraudFighter UV16 and POS15 light fixtures have borne markings indicating that the proper replacement light bulb is the T5UV16-POS15. For this reason, FraudFighter will continue to use the new part number, T5UV16-POS15 as the replacement bulb to be used by the FraudFighter UV16 and POS15 UV detectors, and will not be using the UVF861 mark on any of its replacement light bulbs.

As mentioned above, using any other bulb other than a FraudFighter T5UV16-POS15 bulb as a replacement bulb for the UV-16 or the POS-15 will invalidate the warranty on that UV-16 and POS-15. It is VITALLY IMPORTANT that you not use a different replacement bulb part number. The T5UV16-POS15 is compatible will all Fraud Fighter models UV-16 and POS15 products.

This experiment is #28A of Physics with Vernier. The experiment in the book includes student instructions as well as instructor information for set up, helpful hints, and sample graphs and data.

In 2003, UVeritech, Inc., the parent company of FraudFighter Products, began to manufacture and sell the UVF861 bulbs to our clients. These bulbs were produced by us for use in our UV16 and POS15 ultraviolet counterfeit detection machines. To our surprise, in 2012, the U.S. Patent and Trademark Office (USPTO) issued a trademark registration for the mark, UVF861, to a Chinese company. This was more than 9 years after FraudFighter had begun using the UVF861 mark in public commerce. FraudFighter challenged this registration, and filed a lawsuit with the USPTO to cancel this trademark registration.

During the nearly 3-year period in which the USPTO matter was underway, because we did not know how the case would ultimately be decided, FraudFighter chose to use a new part number for the UVF861 bulb. This new part number is T5UV16-POS15

An ideal polarizing filter will remove all but the electric fields that are parallel to the axis of the filter. The light remaining is then said to be polarized. A second filter can be used to detect the polarization; in this case, the second filter is called an analyzer. The transmission through the second filter depends on the angle between its axis and the axis of the first filter. In this experiment you will study the relationship between the light intensity transmitted through two polarizing filters and the angle between the filter axes.

In some FraudFighter fixtures, you will see the part number F4T5 printed on the bulb. This is a standardized part number which is fully interchangeable with the UVF-461 number we produce in our factory.

“Based on the record, we conclude that, as between Petitioner’s and Respondent’s competing claims to own the mark UVF861 for light bulbs that is the subject of the registration, Petitioner (sic: FraudFighter) is the owner. (Trademark Trial and Appeal Board; UVeritech, Inc. v. Amax Lighting, Inc., Cancellation No. 92057088)

On June 29, 2015, the USPTO rendered its decision in favor of FraudFighter. The trademark under the other party’s name is cancelled, and,

where I0 is the intensity when the angle θ between the polarizer axes is zero. In this experiment, you will see if this law is useful in describing your polarizing filters.

To explain the darkened lenses, we need to think of the light as an electromagnetic wave. An electromagnetic wave has varying electric and magnetic fields perpendicular to the direction the wave is traveling. This experiment focuses only on the electric field variation, represented by a vector. Light emitted from a typical source such as a flashlight is randomly polarized, meaning that the electric vector points in varying directions.
