Peter DeFazio (D-Ore.) pressured the Coast Guard into spending $55,000 to repair the Fresnel lens
. He then sponsored a bill that transferred ownership of the lighthouse, located north of Florence, to the Oregon Department of Parks and Recreation, which already owned the land on which it sits.
All experiments were carried out in a pilotscale Fresnel lens
(5 Fresnel lens
, which was made of PMMA with a thickness of 2 mm, a pitch of 0.5 mm, a facet depth of 0.2 mm, and Fresnel circles of 395 were used) mounted inclined plate curvature channel (IPCC) reactor (Figure 1).
Each two light dependent resistor sensors were placed on the Fresnel lens
along the east-west and north-south direction to control the N-S axis and E-W axis movement by two stepper motors, respectively.
It began operating with a new kerosene lamp inside the relocated Fresnel lens
, allowing its light to be seen for 13 miles.

The advantage of the Fresnel lens
compared to a light guide used in  is significant as collimation of light provides better signal to noise ratio (SNR) at lower power consumption and allows the construction of a more compact and easier to assemble sensor in comparison with a light guide.
(WFT).The supplier's Fresnel Lens
film is featured on the La Mia Perla fragrance carton, which is described in detail later in this article.
Usually, Fresnel lens
is used as an LCE, for the advantages of reduced thickness and light weight.
Motion detectors containing one PIR sensor, a Fresnel lens
with a cone-type beam, and a binary output are very efficient for detecting any type of motion, including human or pet motion.
