Optical material
|
Simphoton is capable
of fabricating a wide variety of optical components with
various optical materials. The most important material
properties to consider for an optical element are transmission
versus wavelength, index of refraction, thermal characteristics,
mechanical and chemical characteristics and cost.
To select the right
materials seems overwhelming. The simplest way is to let
Simphoton know your applications, and we select them for
you. Basic optical material datasheet.

Thin film optical coating
technology
|
Simphoton can product
a wide variety of coatings from simple single layer antireflection
coatings using Mg F2 and mirror coatings to complex multilayer
dielectric stacks. Typical types of dielectric coatings
are BBAR, V-coatings, Dual wavelength AR coatings, High
reflection coating and Sharp long pass or short pass filter
coating.

Waveplate
|
Waveplates, also called
retardation plates or phase shifters, can make a specified
phase difference between s-polarization and p-polariztion.
There are half waveplate and quarter wavplate.
