At OPTOStokes, we deliver high-performance optical filters for photonics professionals. Our 505nm long wave pass filter, crafted with advanced dielectric coating technology, precisely separates wavelengths by blocking shorter wavelengths while transmitting longer ones—essential for applications requiring accurate spectral isolation.
A long wave pass filter permits light above a specified cutoff (505nm here) while blocking shorter wavelengths, making it indispensable in scientific research, industrial inspection, and imaging systems.
Key Advantages:
- Sharp 505nm cutoff for precise wavelength selection
- High transmittance (>90%) across 510-1100nm maximizes signal throughput
- Superior blocking (<1%) in 350-500nm eliminates background interference
- Durable optical glass construction ensures long-term stability
Applications:
- Fluorescence Microscopy: Isolates GFP emission (≈509nm) from 488nm excitation light, enhancing image contrast for cellular studies.
- Spectroscopy: Separates sub-500nm laser excitation from Raman scattering (>510nm), improving signal-to-noise ratio.
- Machine Vision: Reduces blue/UV interference in industrial sorting, boosting defect detection accuracy.
With extensive stock of standard sizes and thicknesses, OPTOStokes enables quick . We also offer custom fabrication—circular, square, or irregular shapes, plus lens mount integration—to match your system. Our production line ensures consistent quality meeting international standards, with reliable lead times.
