The **OPTOStokes LP595 Longpass Filter** (P/N: 21102765) is a high-precision longpass filter designed for critical optical paths requiring an extremely sharp transition between the visible and near-infrared (NIR) spectrum. Engineered with advanced multi-layer optical coating, this component ensures that less than 1 percent of light is transmitted below 590nm while providing superior throughput up to 1100nm.
The core performance is defined by its highly accurate Cut-on Wavelength (CWL) at 595nm, making it indispensable for systems where spectral accuracy directly impacts measurement quality and image contrast.

Key Applications and System Integration
The precise 595nm CWL combined with the broad, high transmission filter passband into the NIR region makes the LP595 essential for several demanding fields:
- Fluorescence Microscopy: Used as an emission fluorescence filters for fluorophores excited near 595nm or for isolating red-shifted emission light from the excitation source.
- Machine Vision & Inspection: Critical for high-contrast imaging in the red/NIR spectrum, often for sorting or detecting specific features invisible to the human eye.
- NIR Filter and Sensing: Serves as an effective component in multi-spectral sensing and general spectroscopy where visible light interference must be efficiently blocked.
