BP470-10 대역통과 필터(CWL=470nm, FWHM=10nm)

Fluorescence Microscopy (Excitation Filter)

• Primary Use: This is the standard excitation filter for GFP (Green Fluorescent Protein) and FITC (Fluorescein isothiocyanate).
• How it works: It cleans up the light source to ensure only 470nm light hits the sample. The high blocking (OD6) prevents any green or red wavelengths from the light source from "leaking" into the detector, which would wash out the faint fluorescence signal.

Recommended Light Sources

• High-Power Blue LED (470nm): Provides a highly efficient, targeted output that overlaps perfectly with the BP470-10 passband, minimizing waste heat and requiring less aggressive blocking of unwanted wavelengths compared to broadband sources.
• Broadband Arc Lamp (Xenon/Mercury): Offers a continuous spectrum that covers the 470nm excitation band, which is useful if the system must also support multiple other fluorophores (e.g., DAPI or TRITC) by simply switching filters, though it generates significant heat and requires the BP470-10's OD6 blocking to be fully effective.

Chemical Analysis & Spectroscopy

• Used to isolate specific spectral lines for flame photometry or water quality analysis sensors (e.g., measuring turbidity or specific chemical absorption at 470nm).

Recommended Light Sources

• White LED (Broadband): Provides a stable, cool, and long-lasting source that contains the necessary 470nm blue component, making it ideal for portable water quality sensors where power efficiency and durability are critical.
• Xenon Flash Lamp: Delivers a high-intensity, broad-spectrum pulse that ensures a strong signal at 470nm, which is necessary for benchtop spectrophotometers attempting to read through dense or highly turbid samples.
