| High Light | customizable SPF optical filter ，DWDM filter with specific wavelength ，optical filter meets wavelength requirements | ||
Product Description
SPF (Single-Pass Filter) is a high-performance optical component designed to selectively transmit a specific narrow wavelength band while efficiently blocking all other wavelengths, enabling precise light signal purification in various optical systems. Engineered with advanced thin-film deposition technology and high-purity optical substrates (such as fused silica or optical glass), this SPF ensures a sharp cutoff edge and minimal wavelength leakage, guaranteeing exceptional signal-to-noise ratio.
With outstanding optical performance, the filter offers high transmittance (>90%) for the target wavelength and deep blocking (>OD5) for unwanted wavelengths, effectively eliminating crosstalk and interference. 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 spectrometers, optical sensors, or medical diagnostic devices, SPF provides reliable single-wavelength filtering solutions, supporting accurate data acquisition and high-performance operation in scientific research, industrial production, and biomedical applications.
Key Features
Precise Wavelength Selection: Narrow bandwidth (1–20nm customizable) for targeted single-wavelength transmission.
High Optical Purity: Sharp cutoff edges and deep blocking of stray wavelengths, minimizing signal interference.
Superior Transmittance: >90% transmittance for the target wavelength, ensuring maximum light utilization.
Durable Construction: Scratch-resistant, moisture-proof coatings and high-purity substrates for long-term reliability.
Broad Compatibility: Suitable for integration with spectrometers, sensors, cameras, and other optical devices.
