745nm Bandpass Filter | FWHM 45nm, OD6 High Blocking

The OPTOStokes 745nm bandpass filter is engineered for high-performance near-infrared (NIR) applications. Delivering an average transmission exceeding 90% (Tave >90%) within the 745-755nm band, it ensures maximum throughput for weak optical signals. Combined with an ultra-deep out-of-band blocking of ODave >6 across the 200-1100nm range, this filter provides the exceptional signal-to-noise ratio required by high-precision optical systems.

Technical Specifications

Key Applications

Due to its high NIR transmission and steep slope transitions, this filter is highly optimized for small animal in vivo imaging, fluorescence microscopy, and clinical diagnostic instrumentation. It effectively isolates specific fluorophores (such as Cy7 or Indocyanine Green / ICG excitation/emission lines) while completely suppressing autofluorescence and excitation crosstalk.
