Optoelectronic Mold compounds can replace a lot of existing technology in Ambient light sensors, lens filters and proximity sensors. They have a lower cost compared to traditional glass, since standard optical filters can often run into the hundreds of dollars. This is mainly because they require fewer process steps since no adhesive is needed, as the filter is incorporated into the encapsulant. Additionaly, they can have custom cut-off and bandpass with formulations tailored to your wavelength requirements.
White, highly reflective epoxy molding compounds, also abreviated as WMC, are epoxy molding compounds that are filled with a highly reflective filler that stays reflective even after exposure to heat and UV for long periods of time. We offer a range of highly reflective, white, non-yellowing epoxy mold compounds for led packages and lighting applications that require a high-performance non-yellowing compound with high brightness and reflectivity.
Clear epoxy Mold compounds have different filler and chemistry than most common EMCs. Optically clear compounds are also used for LED devices, and to encapsulate optical or optoelectronic devices that require both a high level of light transmittance as well as a good level of mechanical protection. In a similar process to Glob Top encapsulation, a literal glob of clear encapsulant is dropped directly into place on top of the LED. In other production processes, optically clear compounds are used to cast the LED’s final body. Phosphor, colored dyes, and diffusant concentrates can be added to this liquid encapsulant to fine tune it to your needs and alter its optical properties.
