Multi-Bandpass optical filter is a filter that can transmit multiple spectral bands simultaneously. It can extract different spectral information in different wavelength ranges, thereby enabling multi-band analysis of the target. It is widely used in remote sensing mapping, sensors, medical, transportation, and other fields.

The traditional design of bandpass filters in UV involves metals (usually Al or Ag). Induced transmission design with metal and dielectric membranes provides cost-effective UV filters and high barrier across the entire visible wavelength range. Disadvantages include low transmittance (usually around 20%) and not very steep spectral edges.

A Raman spectrometer uses the characteristics of Raman spectra to determine the structure of molecules. Raman spectrometers are widely used in fields such as chemistry, physics, biology, and medicine. The core optical path of a Raman spectrometer consists of a long-pass filter, a dichroic mirror, and a narrow band-pass filter.

The performance of optical filters in QPCR determines the instrument's detection accuracy. They have high transmittance and suppress background noise to OD6; the excitation and emission filters are highly isolated from each other, effectively suppressing cross-interference during multi-channel measurements.

Fluorescent dyes have important applications in biological and chemical research. Choosing the appropriate fluorescent dye can improve the accuracy and visualization of experiments. For common fluorescent dyes such as FAM, ROX, FITC, and CY3, a series of filter combinations have been launched, including excitation filters, emission filters, and dichroic mirrors.

Notch filters are a type of optical filter that selectively blocks specific frequency spectra within a wide spectral range. Their main function is to remove interference at specific frequencies in optical signal processing, thereby improving signal quality; or to prevent harmful strong light at specific frequencies.
