Students can use the Fresnel Lens to conduct investigations about technological devices use the principles of wave behavior and wave interactions with matter to transmit.

Students can use the Fresnel Lens to make observations and measurements to identify materials based on their properties.

While other radiometers require manual calibration between different lens widths, Radiometer X is engineered to automatically adjust to all lens diameters.

Radiometer X is compatible with all curing lights. It is designed to measure the crucial light intensity between the 380-550 nanometers wavelength range. Radiometer X provides readings between 300 to 3,000 mW/cm2.

Students can use the Fresnel Lens to make observations to provide evidence that energy can be transferred from place to place by heat currents.

When combined with the SDI Radii LED curing light range, the Radiometer X delivers an accuracy (r value) of 0.95 , ensuring the most accurate reading.

Students can use the Fresnel Lens to apply scientific principles to design, construct, and test a device that either minimizes or maximizes thermal energy transfer.

Students can make observations of the Fresnel Lens to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.

Radiometerhow it works

Students can use the Fresnel Lens to plan and conduct an investigation to provide evidence that the transfer of thermal energy when two components of different temperature are combined within a closed system results in a more uniform energy distribution among the components in the system (Second Law of Thermodynamics).

Results from a study of 7 radiometers and 23 curing lights confirmed that Radiometer X has outstanding accuracy compared to its peers – some of which are extremely expensive and slower units.

Students can use the Fresnel Lens in an investigation to design a solution to a complex real-world problem by breaking it down into smaller, more manageable problems that can be solved through engineering.

Students can use the Fresnel Lens to develop and use a model to describe how waves are reflected, absorbed, or transmitted through various materials.

Students can use the Fresnel Lens to design, build, and redefine a device that works with given constraints to convert one form of energy into another form of energy.

Students can use the Fresnel Lens to develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem.
