Product Description
LPF (Long-Pass Filter) is a critical high-performance optical component designed to transmit long-wavelength light while effectively blocking shorter wavelengths, enabling precise light signal separation in various optical systems. Engineered with advanced thin-film coating technology and high-purity optical substrates (such as fused silica or optical glass), this LPF ensures sharp cut-off edges, minimizing wavelength overlap between transmitted and blocked light.
With excellent optical performance, the filter offers high transmittance (>90%) for target long wavelengths and deep blocking (>OD4) for unwanted short wavelengths, significantly improving signal-to-noise ratio in optical detection. Its robust construction features scratch-resistant and moisture-proof coatings, ensuring stable operation across a wide temperature range (-20°C to 70°C) and harsh environmental conditions. Whether integrated into imaging systems, spectrometers, or optical communication devices, LPF provides reliable light filtering solutions, supporting accurate data acquisition and high-performance operation in scientific research, industrial production, and medical diagnostics.
Key Features
Precise Wavelength Selection: Sharp cut-off wavelength (customizable from 350nm to 2500nm) for accurate separation of long/short wavelengths.
High Optical Efficiency: High transmittance for target wavelengths and deep blocking of stray short wavelengths, reducing signal interference.
Durable Construction: Scratch-resistant, moisture-proof coatings and high-purity substrates ensure long-term reliability and stability.
Broad Compatibility: Suitable for integration with spectrometers, cameras, sensors, and other optical devices across multiple industries.
Wide Operating Range: Performs stably in extreme temperatures and humid environments, adapting to laboratory and field applications.
Customizable Options: Tailorable cut-off wavelength, size, and mounting design to match specific system requirements.
Applications
Biomedical Imaging: Used in fluorescence microscopy, flow cytometers, and medical diagnostic devices to filter unwanted short-wavelength background light.
Industrial Inspection: Applied in machine vision systems for semiconductor, display panel, and food packaging inspection to enhance image clarity.
Spectroscopy Analysis: Integrated into UV-Vis-NIR spectrometers for chemical analysis, environmental monitoring, and material composition testing.
Optical Communication: Utilized in fiber optic systems to block short-wavelength noise and ensure stable long-wavelength signal transmission.
Astronomical Observation: Employed in small telescopes and astronomical imaging equipment to filter atmospheric short-wavelength interference.
Portable Sensing Devices: Compatible with handheld optical sensors for on-site testing (e.g., water quality analysis, food safety detection).
