This four-filter set is specially designed to achieve high-performance fast FRET (Fluorescence Resonance Energy Transfer) imaging for green donor fluorescence and red acceptor fluorescence. FRET measurements using wide-field microscopy are challenging – using the best possible filters can make a significant difference. These filter combinations provide excellent brightness and signal-to-noise ratio while minimizing the undesirable donor-acceptor crosstalk.

| Filter Role | Filter Size | Maximum Thickness |
| Exciter (Diameter) | 25.0 mm | 5.0 mm |
| Emitter (Diameter) | 25.0 mm | 3.5 mm |
| Dichroic (L × W) | 25.2 mm × 35.6 mm | 1.1 mm (Can accept a 2 mm dichroic) |
| Topic | Description |
| Cleaning Optical Filters | Instructions for cleaning hard coated optical filters |
| Filter Reliability | Compares the performance and reliability of hard coated filters to traditional soft-coated filters and provides information about the testing standards for Semrock filters |
| Working with Optical Density | Tables to describe the relationship between OD and transmission with tips for quickly calculating OD |
| What is Pixel Shift, and how does the Semrock ZERO™ option help? | Why Pixel Shift degrades multicolor fluorescence imaging performance, and how the ZERO™ option mitigates this for Avant and BrightLine filter sets. |
Optimized – Filter set is specifically optimized for that fluorophore.
Compatible – Should result in nearly ideal performance in most situations.
Acceptable – Actual performance is dependent on specific experimental conditions.
