The BP600nm is a high-performance narrow bandpass filter engineered for precise wavelength selection. Its sharp spectral edge ensures >90% transmission at 655-665nm, paired with deep blocking (T<1%) across 350-1100nm—minimizing stray light interference in critical applications.
Applications
Perfectly suited for scenarios requiring 660nm wavelength isolation:
- Fluorescence microscopy: Filters excitation light for 660nm fluorophores (e.g., Cy5), enhancing signal-to-noise ratio.
- Spectroscopy: Isolates 660nm emission lines in material analysis or biochemical assays.
- Machine vision: Improves contrast in quality inspection systems targeting 660nm markers (e.g., barcode scanning with red LEDs).
Custom Options
Beyond standard specs, we offer tailored solutions:
- Shapes: Circular, square, or custom (irregular) cuts.
- Mounting: Optional lens mounts (retainers) for easy integration into optical systems.
