Beckman Coulter 585/42 nm Bandpass Filter for CytoFLEX (A01-1-0052)
The Beckman Coulter 585/42 nm Bandpass Filter (A01-1-0052) is an optical bandpass filter module designed for use in modular flow cytometer filter arrays. It transmits emission centered at 585 nm with a 42 nm full width at half maximum (FWHM), enabling selective detection of fluorochromes excited by 488 nm and 561 nm lasers.
- Provides a 585 nm center wavelength with a 42 nm passband.
- Repositionable bandpass module compatible with wavelength division multiplexer filter holders.
- Optimized for detection of PE and related fluorochromes excited near 488-561 nm.
- Improves signal separation by narrowing emission collection and reducing spectral overlap.
- Suitable for multiparameter fluorescence and cellular assays.
