    Frequently Asked Questions (FAQ)
    1. What is the typical peak transmission (Tp) of the bandpass filters?
    Most visible light bandpass filters in our stock feature a high peak transmission (Tp) of greater than 90%, ensuring excellent signal throughput for optical applications.
    2. What sizes are available for these bandpass filters?
    Our standard size capability ranges from a minimum diameter of Φ0.1 mm up to 300 mm to meet various instrument integration requirements.
    3. What is the difference between OD4 and OD6 cut-off depth in these filters?
    OD4 filters offer a blocking level of 10^-4 (0.01% transmission) in the cut-off range, while OD6 filters provide a deeper blocking level of 10^-6 (0.0001% transmission) for highly sensitive fluorescence applications like FAM, Hex, and Rox.
    4. What are the common biotech applications for the specified filter models?
    Specific models like BP470/30K (FAM Ex), BP525/20K (FAM Em), and others are optimized for standard fluorescence dyes (FAM, Hex, Rox, Cy5) used in PCR, DNA sequencing, and medical diagnostics.
    5. Can I order a custom bandpass filter if my required specification is not listed?
    Yes. If you require a custom center wavelength (CWL), half-bandwidth (HPB), or specific size that is not shown in our stock list, please contact us directly for custom fabrication options.
