Optical Products To Meet New and Emerging Technical Challenges
Solutions for refractive index, viscosity, transmission vs. wavelength, custom volume, temperature, environmental parameters and more.
Optical Plastics (AL-62xx Series)
A high purity, high refractive index, optically clear plastic. Moldable by conventional injection molding techniques. Optical transmission and environmental resistance are equal to optical grade
polycarbonate, with less stress birefringence than polycarbonate. Typically used for lenses in camera and
video cell phones, and display backlights.
Hard materials with Shore D durometer. All are suited to making thin films for use in PCB optical waveguides, microlens arrays, prism films, or low dielectric layers.
Can be applied by spin coating.
Compatible with CMOS substrates and fabrication techniques. Excellent adhesion and chemical
resistance.
Soft Cure Materials with a consistency approximating Jell-O (Shore 00 ~ 30). Used for bulk encapsulation where the low modulus provides
stress relief from mismatches in thermal coefficients of
expansion. Good adhesion to a variety of substrates and a range of refractive indices to couple the light
between the two materials of the joint.
ÅngströmSphere™ silica spheres are manufactured using our own proprietary technologies which allow the essential properties of amorphous silica to be combined with unique control of duplication,
both in form and particle size.
A Teflon-like polymer suspended in an evaporative solvent that leaves behind an amorphous film when the solvent evaporates. Film
thickness is controlled by the concentration of the
dissolved polymer; standard concentrations create film thicknesses of 200nm to 10u; concentration is
easily customized by the user to make any layer thickness in between. Can be used for antireflection
coating or low surface energy masking (mold release).
1-Part (non-curing gels also known as thixotropic gels, or greases, these are 1-part materials that flow when pressure is applied and remain in
place when the force is removed (like
toothpaste). These materials are generally used to displace the air gap between two optical elements and
do not form a permanent bond between the two elements; generally, need other mechanical fastening to
insure structural integrity of the joint. Joints interconnected in this way are easily unmade and remade.
