INBP2360 SWIR Narrow Bandpass Filter | CWL 2360nm, FWHM 150nm, OD2

The OPTOStokes INBP2360 is a high-precision infrared narrow bandpass filters engineered for online moisture meter reference channels and near-infrared spectroscopic analysis. Fabricated with advanced thin-film coating on sapphire and germanium substrates, it delivers peak transmission greater than 80 percent at a center wavelength of 2360nm with ±30nm tolerance, and a full width at half maximum of 150±30nm. As a high-performance member of SWIR filters, this component provides reliable optical density greater than 2 across the entire 1700–5500nm out-of-band range, ensuring clean signal isolation for high-accuracy analytical instruments and quantitative spectroscopic measurement systems.

Technical Specifications

Applications

This SWIR narrow bandpass filter is specifically optimized as a reference channel for online moisture analyzers paired with absorption peak channels to eliminate common interference, and for near-infrared spectrometers analyzing O-H, C-H and other characteristic chemical bonds in organic substances. Its stable spectral response and robust substrate make it ideal for:

• Online moisture meter reference channels for interference cancellation

• Near-infrared spectroscopy and organic functional group analysis

• Food and agricultural product moisture and composition testing

• Pharmaceutical raw material identification and quality measurement

• Petrochemical component detection and process monitoring

• Industrial on-line composition analysis and quality control systems

Pain Points & CTA

Analytical instrument and moisture detection teams often face critical challenges: inconsistent reference channel wavelength leading to measurement deviation, insufficient broadband blocking causing elevated baseline noise, and long lead times for custom sapphire-germanium infrared components. These issues can reduce detection accuracy, increase calibration frequency, and delay instrument deployment schedules. At OPTOStokes, we solve these problems with our extensive ready-to-ship inventory, precision thin-film 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.
