Fluorescence Filter Cube: Fluorescence Filter Cube Holders
The Fluorescence Filter Cube is a detachable filter cube designed to integrate excitation and emission filters—along with a dichroic mirror—for fluorescence microscopy. Compatible with major microscope brands, these holders enable precise control over light wavelengths, critical for imaging fluorescent probes and proteins.
Key Features
- Extremely sharp wavelength cut-ons for accurate spectral separation
- High transmittance (90–97%) for excitation and emission filters, maximizing signal intensity
- Enhanced fluorescence collection efficiency, reducing excitation intensity requirements and minimizing sample photobleaching
- Available in longpass (for single-stained samples) and bandpass (for multi-stained sample separation) configurations
Compatibility with Major Microscope Brands
FL CUBE holders are engineered to fit standard filter sizes. Below is the compatibility guide for Olympus, Nikon, Leica, Zeiss, and other leading brands. Note: Confirm filter dimensions before purchase. OPTOStokes offers compatible filters with equivalent performance to OEM versions at a more competitive price.
