BP470-30 대역 통과 필터(CWL=470nm, FWHM=30nm)

Fluorescence Excitation (Microscopy)

This is an ideal Excitation Filter for blue-excited fluorophores. It cleans up the light source to ensure no "leakage" enters the emission channel.

• Target Fluorophores: GFP (Green Fluorescent Protein), FITC (Fluorescein), and Acridine Orange.
• Function: It shapes a 470nm light source to strictly excite the sample without overlapping with the green emission signal (typically >500nm).

Recommended Light Sources

• High-Power Blue LED (465nm/470nm): Ideal spectral match; the filter trims the LED's "spectral tails" to create a pure excitation source without heating the sample.
• DPSS Blue Laser (473nm): High intensity at a specific wavelength; the 30nm bandwidth captures the full laser line while effectively rejecting pump diode noise or plasma glow.
• Xenon Arc Lamp: Provides high-intensity broad spectrum power; the filter slices out a potent 470nm beam from the white light, useful for systems requiring high versatility.

High-Contrast Machine Vision

• Used to image blue features on a multi-colored object.
• Stimulating fluorescence in industrial adhesives or UV-tracers that absorb in the blue range.

Recommended Light Sources

• Blue LED Illuminator (470nm): Provides the most efficient monochromatic light that directly matches the filter's passband. It maximizes contrast by making blue features appear bright (while darkening other colors) and efficiently excites blue-absorbing adhesives without the heat or broad-spectrum "noise" of white light.
• Blue Laser Line Generator (473nm): Delivers extremely high-intensity, structured illumination. This is advantageous for 3D profiling of glue beads or high-speed detection where the camera exposure time is short, as the filter blocks all ambient light while passing the strong laser signal.
