  • Phase Holograms in Polymethyl Metacrylate
    Complex computer generated phase holograms (CGPHs) have been fabricated in polymethyl methacrylate (PMMA) by partial exposure and subsequent partial development. The CGPH was encoded as a sequence of phase delay pixels and written by e-beam (JEOL JBX-5DII), a different dose being assigned to each...
  • Strength and Reliability of Silica Optical Fibers in Automotive Communication Networks (.pdf)
    effects, coatings. As plastic optical fiber (POF) gains widespread use in automotive data bus systems, it faces restrictions that may limit its long-term implementation. For example, current plastic fibers in use for data links are formulated from polymethyl methacrylate (PMMA) which limits the upper...
  • Secrets of Bond Strength
    practices. Thermoplastics, by contrast, are more difficult to bond. Each type of plastic -- ABS, polycarbonate (PC), polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE), polymethyl methacrylate (PMMA), polyamide and polyetheretherketone (PEEK) -- may vary considerably in properties...
  • Silicone Lenses for LEDs Resist UV and High-Temperature Operation
    Over the years, various materials have been used for optics attached closely to the LED chip, beginning with epoxy used directly for the housing of the well-known 5mm LEDs, for example. Today, materials such as PMMA (polymethyl methacrylate, also known as perspex or acrylic), PMMI (polymethyl...
  • Micro-Optical Sensors for Boundary Layer Flow Studies (.pdf)
    sensor element was fabricated by two-sided. lithography on a 500 mm thick quartz substrate. The slits and. collecting window on the front were fabricated by direct-write. electron-beam lithography followed by wet etching of. evaporated chrome. The polymethyl methacrylate (PMMA). diffractive optical...
