Bandpass Interference Optical fluorescence Filters Cy3 FOR the fluorescence microscopy filter

Product Description

 1. Brief Description:

Fluorescence imaging filters are including excitation filter,emission filter and unmounted dichroic mirror. It's deep blocking OD5 OD6 above and high transmission ensure the maximum brightness and high contrast for fluorescence imaging. Thus offer the critiera for clinical and research judgement


2. Description for Cy3:
Cy3 dye is a bright, orange-fluorescent dye that can be excited using the 532 nm laser line and visualized with TRITC (tetramethylrhodamine) filter sets. In addition to immunocytochemistry applications, Cy®3 dye is commonly used to label nucleic acids.


3. Advantage of Optolong Fluorescence Filter
Yulong Optics's provide excellent fluorescence filters for producing bright image and dark background. The characteristic is shown below:
1)Transmission >85% and OD blocking>5
2 ) IAD hard coating
3 ) Substrate by glass from Scott or fused silica
Yulong's fluorescence filters could be applied to fluorescence Microscopy, DNA sequencing, Point-of-Care, flow Cytometry, high content analysis & screening, surgical Devices, forensics, microplate Readers
