In the demanding field of multi-channel fluorescence microscopy and advanced instrumentation, precision is non-negotiable. The OPTOStokes 555nm, 655nm, and 835nm Triple Bandpass Filter is engineered to simultaneously capture three distinct spectral bands—Green, Red, and Near-Infrared (NIR)—with exceptional clarity. By enabling the detection of multiple fluorophores or laser lines without the need for mechanical filter wheels, this component significantly enhances system speed and data throughput.
Designed for R&D engineers and system integrators requiring high signal-to-noise ratios, this filter utilizes advanced hard-coating technology. It delivers average transmission rates greater than 90 percent across all three passbands while maintaining deep blocking (transmission less than 1 percent) in the out-of-band regions from 350nm to 1050nm. This ensures that crosstalk is minimized, making it an ideal solution for complex imaging setups and biomedical applications.
