Product Details

Product Overview

Fluorescence filter is a key component used in biomedical and life science instruments. Its main function is to separate and select the characteristic wavelength spectrum from the excitation light and emission fluorescence of the substance in the biomedical fluorescence inspection and analysis system.

✦ Fluorescence filters are typically characterized by a deep cut-off depth and low autofluorescence. Multiple filters can be glued together to form a fluorescence filter, which offers high cost performance.

Application Field

Fluorescence filter is used in real-time fluorescence quantitative PCR instruments, which is widely used in molecular biology, food safety detection, public health epidemic monitoring, and other industries.

Fluorescence filter is used for detecting a variety of dyes and probes, for example:

🔬 FAM / SYBR Green / Green / HEX / TET / Cy3 / JOE / ROX / Cy3.5 / Texas Red / Cy5 / LC Red640 / Cy5.5 etc.
