Polarization Maintaining Filter Splitter(PMFS)
The Polarization Maintaining filter splitter is a 3 or 4 ports micro-optic device built with PM fiber. The PMFS transmits a signal from one of the input to two outputs with various ratios while maintaining the polarization of the signal. It is characterized with low insertion loss, high return loss, high extinction ratio and excellent environmental stability and reliability. There are two type of working axis, one is both axis working and another is Fast axis blocked.

Fluorescence Filter
Optical Filters
Sunday-optics
Temperature: >90% Closed [200-1200nm]: OD6 200-1200nm Flatness [@633nm]: 1/4 lambda@633nm
Fluorescence filters extract fluorescence energy or images in fluorescence systems. Strong stray-light isolation and low autofluorescence suit PCR, fluorescence immunoassay and microscopy. Blocking typically exceeds OD5, optical density OD=-lgT. As key biomedical/life-science components, they offer deep blocking, low autofluorescence, good transmission and surface form. High-quality versions use one colorless transparent glass substrate coated on both sides, improving imaging over bonded multilayers or colored-glass-assisted blocking, though harder manufacture raises cost. A typical set comprises excitation filter, emission filter and dichroic mirror; some systems omit the dichroic, and laser excitation may eliminate the excitation filter. Excitation filter: Passes only excitation wavelengths; bandpass has largely replaced shortpass. An engraved arrow indicates recommended light direction. Emission filter: Passes sample fluorescence and blocks other wavelengths. Emission is longer/redder than excitation; bandpass or longpass types are used, with direction arrows. Dichroic mirror/beamsplitter, also called a color separator, is mounted45° to the microscope path. It reflects excitation and transmits emission, with reflectance>90% and transmission>90%. Rejected bands reflect rather than absorb; transmitted/reflected colors are complementary.
