| Product List |
This series of fluorescence filters utilizes a high-transmittance optical design, achieving transmittance exceeding 98%. This effectively reduces light loss and increases fluorescence signal strength by approximately 50% compared to conventional filters. This efficient use of light energy not only enhances image brightness but also significantly improves the signal-to-noise ratio, enabling clearer and more stable detection of weakly fluorescent samples. Rigorous spectral uniformity testing ensures excellent stability and repeatability across the entire wavelength range, making it ideal for high-sensitivity fluorescence detection applications.

The filters utilize advanced ion beam sputtering (IBS) coating technology, resulting in extremely high film density and adhesion. The IBS process controls film thickness with atomic-level precision, resulting in a sharper cutoff edge and smoother transmission band. Compared to traditional evaporation coating technologies, IBS coatings offer superior temperature stability and resistance to humidity and heat, maintaining high performance without degradation over time, ensuring stable and reproducible experimental data.
This series of fluorescence filters is designed specifically for fluorescence microscopy systems and perfectly matches common fluorescent probes such as FITC, TRITC, DAPI, and Cy5. The filters' high optical precision and excellent blocking performance help achieve high-contrast imaging and reduce background light interference in microscope systems. Whether used for life science research, cell imaging, or multi-channel fluorescence analysis, these filters provide stable and reliable optical performance.
To meet the needs of diverse scientific and industrial applications, these filters can be customized by center wavelength (CW). Users can select the desired center wavelength and bandwidth range based on their specific excitation light source and fluorescent dye characteristics. Custom filters are precisely designed and spectrally optimized according to customer specifications to ensure optimal matching and system compatibility, resulting in higher imaging efficiency and signal resolution.
