Dielectric filter solutions for PCR analyzers
Enabling SARS-CoV-2 detection with high-performance fluorescence filters by Optics Balzers
Standard off-the-shelf optical filters often struggle to fulfill the challenges set by SARS-CoV-2 detection in High-End PCR analyzers. Optics Balzers now offers next generation filter solutions able to meet the different requirements set by markers like Cy5. In contrast to filters produced with conventional deposition techniques, the coating process is pushed to the limits in order to address typical effects like bleed-through and low transmission values. This allows for best-in-class sensitivity in High-End PCR analyzers.
The precise cut-on and cut-off wavelengths of the next generation filters are customized in order to maximize the performance of PCR setups, while exceptionally steep spectral edges ensure optimal separation between excitation and emission signals. The superb out-of-band blocking is achieved by using fully dielectric thin-films, ensuring highest passband-transmission and excellent stability. Environmental resistance and long-term performance have been rigorously tested in accordance to MIL-STD-810F, MIL-C-48497A, MIL-C-675C, as well as DIN ISO 9022.Benefits
- Exceptionally high passband transmittance allows for highest sensitivity
- Deep blocking for best in class signal-to-noise ratio
- Steep spectral edges to avoid optical bleed-through
