The **OPTOStokes LP610 Longpass Filter** (P/N: 21102764) is a high-performance longpass filter engineered for applications that require stringent spectral separation between the visible and near-infrared (NIR) ranges. This filter provides a sharp cut-on at **610nm**, effectively transmitting light in the red and NIR spectrum while suppressing shorter wavelengths.
Designed using advanced optical coating techniques, the LP610 maximizes throughput for your detection system. The passband exhibits an average transmission rate of **greater than 90 percent** across 600nm to 1100nm, ensuring minimal signal attenuation. Simultaneously, the filter achieves excellent noise reduction by blocking light from 350nm to 575nm with a transmission rate of **less than 1 percent**.
Technical Specifications
R&D engineers and technical decision-makers depend on precise specifications. Below are the core technical parameters for the LP610 filter:
| Specification | Parameter / Value |
|---|---|
| Product Type | Longpass Filter (LP610) |
| Cut-on Edge Wavelength (CWL) | 610nm |
| Passband Transmission | 600nm - 1100nm @ T average greater than 90 percent |
| Blocking Range | 350nm - 575nm @ T less than 1 percent (High Rejection) |

Key Applications
This high transmission filter is a critical optical component for minimizing background noise and isolating specific long-wavelength signals, making it indispensable for:
- Fluorescence Detection: As an emission filter in fluorescence filters systems, particularly those using red-emitting dyes, by effectively blocking residual green/yellow excitation energy.
- NIR Filter-based Machine Vision: Enhancing contrast and image quality in industrial sorting and quality control by suppressing unwanted visible light noise.
- Medical and Life Sciences: Used in photometry and spectroscopy instrumentation where accurate NIR signal isolation is paramount.
