Description
The M79506 combines a compact 154 nm notch with excellent transmission characteristics across both passbands. Blocking 474-586 nm at 0.25 % depth at 520 nm, this filter achieves 90.7 % blue transmission and 93.9 % red-NIR transmission with a peak of 95.3 %. Its optimized design balances notch width with passband efficiency, making it ideal for applications requiring minimal optical components while maintaining high spectral selectivity.
Key Advantages
- Compact Notch Specification - 154 nm blocking width provides efficient green rejection without excessively constraining passband boundaries
- Low Notch Depth - 0.25 % transmission at 520 nm effectively suppresses green fluorescence and 532 nm laser scatter
- Ion-Assisted Hard-Oxide Coatings - Multilayer construction delivers long-term durability and environmental stability in laboratory settings
- Custom Substrate & Geometry Options - Round, square, and free-form designs on Borofloat, soda-lime, Schott D263 T, and Corning Eagle XG from 5-450 mm
- Consistent Peak Performance - 95.3 % transmission across both regions minimizes signal attenuation in multi-channel systems
Typical Applications
- Confocal Microscopy - Isolates blue excitation photons from red-emitted fluorescence in high-resolution imaging
- Laser Scanning Cytometry - Enables efficient 405/532/633 nm three-laser systems with minimal cross-excitation
- Optical Beam Combining - Simplifies dichroic replacement in wavelength-multiplexed sensor architectures
- Fluorescence Lifetime Imaging - Provides clean spectral separation in time-resolved photoluminescence measurements
- Machine Vision Filtering - Distinguishes blue and red color features while suppressing green channel interference
Rapid prototyping in 2-3 weeks; production capable of meeting volume demands with consistent optical and mechanical specifications.
