LP880nm Longpass Filter | 880nm Cut-on, OD2 Blocking, 0.5mm

The OPTOStokes LP880nm is a high-precision longpass filters optimized for spectral analysis and environmental monitoring applications. Engineered with advanced thin film coating technology, it provides transmission greater than 90 percent across the 890–1100nm near-infrared range, with a 50 percent cut-on wavelength of 880nm within ±5 percent tolerance. This ultra-thin 0.5mm filter delivers reliable high OD blocking across 350–855nm with optical density greater than 2, effectively suppressing visible and short-wavelength interference for accurate analytical instruments performance at 0 degree angle of incidence.

Technical Specifications

Applications

This ultra-thin NIR longpass filter is specifically engineered for spectral and environmental monitoring systems that require clean separation of visible and near-infrared wavelengths. Its stable optical performance and compact form factor make it ideal for:

• Environmental air quality monitoring and gas detection systems

• Spectroscopic analysis and analytical measurement instruments

• Water quality spectral monitoring and pollutant detection

• Industrial emission monitoring and compliance testing

• Atmospheric research and environmental sensing devices

Pain Points & CTA

Environmental monitoring and analytical teams often face critical challenges: insufficient visible-light blocking leading to spectral baseline drift, limited availability of ultra-thin NIR filters, and long lead times for custom thin-form optical components. These issues can reduce measurement accuracy, increase calibration frequency, and delay field deployment schedules. At OPTOStokes, we solve these problems with our extensive ready-to-ship inventory, precision coating technology, and dedicated technical support team. Whether you need a single prototype for testing or high-volume production runs, we deliver precision optical components on time, every time.
