it is applied to fluorescence microscopes, PCR fluorescence analysis instruments. As the core optical components of the instrument, it is widely used in life science research.

The light source of fluorescence microscope is generally mercury lamp, laser and LED, the light source emits light, first through the excitation filter to form a specific wavelength of excitation light, and then reflected by the beam splitter to the objective lens, the objective lens converges the light to the specimen, and finally the specimen is excited by it to produce fluorescence.

PCR fluorescence analysis instrument is an instrument that monitors the reaction process in real time by labeling and tracking PCR products with fluorescent dyes or fluorescently labeled specific probes. The working principle is that the fluorescent dye or fluorescent probe binds selectively and specifically to the target moiety, and then the fluorescent dye or fluorescent probe releases a fluorescent signal under excitation light irradiation. The fluorescent signal is transmitted through the optical system to the photoelectric sensor, which detects the intensity of the fluorescent signal, and the fluorescent intensity is linearly related to the concentration of the target gene, so the whole PCR process can be monitored.

Horkview's filters have high transmittance, so users can obtain high sensitivity, select high-quality coating materials to ensure long-term stable use of the product, and provide users with a one-stop solution for PCR optical modules.

it is applied to enzyme-labeled analytical instrument. Nowadays, enzyme-labeled instrument are widely used in clinical testing, biological research, and environmental science as professional instruments for reading and analyzing the results of enzyme-linked immunosorbent assays. Horkview's filters have accurate central wavelength, good stray light rejection, high signal-to-noise ratio, and long lifetime.

Flow cytometer is an instrument for quantitative multiparameter analysis or sorting of single cells or particles in suspension at high speed and linear flow. The instrument uses a dichroic mirror and a filter as the spectroscopic element.  Horkview's filters have a high transmissivity, allowing the user to obtain a high sensitivity.

Applied to all kinds of UV exposure machines, it can achieve high transmission rate in the UV band.

Applied to laminography, synchrotron system lenses can be processed, they are mainly silicon and germanium aspheric columnar mirrors.

Applications include small imaging systems, small-diameter component processing, and processing of special materials such as sapphire.
