IdealPhotonics' fluorescence imaging filter kit is a set of optical filters optimized for specific fluorescent probes (such as FITC/DAPI). It includes an excitation filter (Ex), an emission filter (Em), and a dichroic mirror. Through precise spectral matching (bandwidth ±10nm) and high transmittance (>90%), it maximizes fluorescence signal acquisition efficiency and suppresses background noise.Parameters such as the excitation/emission passband center wavelength (e.g., 488nm/525nm), bandwidth (±10nm), transmittance (>90%), cutoff depth (OD>6), and dichroic mirror transition slope (<5% cross-region) collectively determine the specific fluorescence signal capture capability and background suppression effect.
