700nm Longpass Filter
The 700nm longpass filter is engineered for precision in demanding optical systems, with parameters that set a high standard for wavelength control. Its design focuses on minimizing interference while maximizing signal integrity—critical for applications where accuracy can’t be compromised.
Core Performance
- Superior Blocking: Achieves <0.1% transmission across 350-630nm, far stricter than standard filters. This exceptional blocking reduces stray light interference, a key advantage for systems sensitive to shorter wavelengths.
- High Transmission: Maintains >90% light throughput from 660-1100nm, ensuring strong signal transmission in the target range.
- Sharp Cutoff: The 50% transmission point (CWL) is tightly controlled at 665nm±5%, creating a clear boundary between blocked and transmitted wavelengths.
- Mechanical Specs: Standard thickness is 1.0mm (other thicknesses available in stock), with a 60/40 surface finish to minimize scattering and maintain optical clarity.
Application Cases
- Advanced Medical Imaging: In near-infrared (NIR) diagnostic equipment, the filter’s strict blocking of 350-630nm visible light ensures crisp imaging of deep tissue structures, where even small amounts of stray light can distort results.
- High-Resolution Spectroscopy: For material analysis requiring precise NIR measurements (e.g., pharmaceutical quality control), it eliminates visible light interference, delivering more accurate spectral data.
- Industrial Sensing: In automated inspection systems using 700-1100nm light sources, it enhances detection reliability by blocking ambient visible light, critical for consistent quality checks on production lines.
