  • Band Pass Filters

    Band pass Filters are defined as a gap pass filters with certain range of pass band. It is used to transmit a range of wavelengths and reflects rest of wavelength on both sides of the pass band. an example spectrum is shown as below. It can be characterized into two types: Narrowband & Broadband pass.

  • Edge Type Filters

    Optical Edge filters which used to transmit a range of wavelengths and reflect the other edge of wavelength bands. It can be characterized into two types: Short edge pass filter(SPF) & Long edge pass filter(LPF).

  • PBS/PBC

    A beam splitter/combiner is an optical device that splits/combines a beam of light in two or the other way. It is a crucial part of many optical experimental and measurement systems, such as interferometers, also finding widespread application in fibre optic telecommunications.
