Optical Fluorescent Filter

What is a Fluorescent Filter?

The Fluorescent filter is a critical optical component in fluorescence microscopy and imaging systems.

It is designed to efficiently separate excitation light from emission light, ensuring high-contrast, high-quality fluorescence images.

It reflects shorter wavelengths while transmitting longer wavelengths.

• Reflects excitation light (short wavelengths) toward the sample.

• Transmits emission light (longer wavelengths) to the detector.

• Provides sharp spectral separation between excitation and emission bands.

Key Features of Fluorescence  Filter

• High reflection efficiency for excitation wavelengths.

• High transmission efficiency for emission wavelengths.

• Steep transition edge for precise spectral separation.

• Durable dielectric coatings for long-term stability.

• Compatibility with high-intensity light sources.

How to Choose the Right Fluorescence Dichroic Filter?

People can choose different typs of fluorescent filters according  to the following factors:

• Cut-on wavelength: Match the filter edge with the fluorophore’s excitation/emission spectrum.

• Spectral performance: Look for filters with high reflection and transmission efficiencies.

• Optical density (OD): Ensure sufficient blocking of unwanted wavelengths.

• Coating durability: Choose filters with hard-coated surfaces for long-term use.

• System compatibility: Ensure size and shape suitable for your devices.

 

And it enables precise wavelength control in biological research, medical diagnostics, and advanced imaging applications.
