--- Understanding Cutoff Optical Filters ---
• What are Cutoff Optical Filters?:
Cutoff optical filters are precision-engineered components designed to selectively transmit or block specific wavelength ranges of light, making them essential in advanced optical systems. At Jingsheng Optics, our cutoff filters are crafted using premium-grade optical glass such as BK7, K9, and quartz, ensuring exceptional spectral control and durability. These filters are particularly vital in applications requiring precise light management—such as laser rangefinders, biomedical imaging, and security monitoring systems. For example, our DBT660 bandpass filter (center wavelength 660±2nm, FWHM ≤115nm) is specifically engineered for 650–660nm laser rangefinders, effectively eliminating stray light while maintaining peak transmittance above 90%. This level of performance is achieved through ion-assisted dielectric coating (IAD), which provides superior film adhesion and environmental stability, passing MIL-STD-810F tests for temperature and corrosion resistance. Each filter undergoes rigorous quality checks, with bubble, stripe, and stress levels classified at C-B/3C or better, ensuring optical clarity and long-term reliability. Whether used in fluorescence analyzers or infrared imaging devices, these filters deliver consistent, high-precision results. Their ability to block unwanted visible light while transmitting targeted infrared signals makes them indispensable in modern optoelectronic systems. With customizable dimensions (4–70mm diameter, 0.35–4.0mm thickness), Jingsheng Optics ensures seamless integration into diverse industrial and scientific setups.
• Applications of Cutoff Filters in Industry:
Cutoff optical filters from Jingsheng Optics play a critical role across multiple high-tech industries. In the aerospace sector, they are used in satellite-based remote sensing instruments where accurate spectral filtering is essential for atmospheric analysis. A real-world case involves a leading Chinese aerospace research institute that partnered with Jingsheng Optics to develop custom UV-blocking filters for spaceborne spectrometers. The solution reduced background noise by over 95%, significantly improving data accuracy during Earth observation missions. In the medical field, our HWB4 infrared transmission visible absorption glass has been adopted by a top-tier diagnostic equipment manufacturer in Suzhou for use in thermal imaging systems. By blocking visible light (≤0.1% transmittance at 400–700nm) while allowing selective IR transmission (700–2500nm), the filter enhanced image contrast in early-stage cancer detection devices. Another notable application is in semiconductor manufacturing: a major chip fabrication plant in Wuxi integrated our neutral gray glass ZAB50 (50% transmittance) into their photolithography alignment systems to control light intensity without color distortion—critical for maintaining pattern fidelity. Additionally, our orange glass CB580 (580±10nm) was selected by a high-end stage lighting company in Shanghai for LED color mixing systems, enabling precise hue control in live performances. These success stories underscore Jingsheng Optics’ ability to deliver tailored, high-performance solutions that meet exacting industrial demands. With ISO9001 certification and proven client satisfaction—including repeat orders from Jiangsu Sanlian Biological Factory and Endershaus (Suzhou)—we stand as a trusted partner in cutting-edge optical innovation.
--- Product Range of Jingsheng Optics ---
• Types of Cutoff Optical Filters Offered:
Jingsheng Optics offers a comprehensive portfolio of cutoff optical filters tailored to diverse technical requirements. Our product line includes UV cutoff glass (ZJB220–ZJB380), golden/yellow (JB400–JB510), orange (CB535–CB580), red (HB600–HB720), and infrared transmission visible absorption glass (HWB760–HWB930). Each series is formulated with distinct spectral characteristics for targeted applications. For instance, the ZWB1–ZWB3 UV-vis absorption glass blocks ultraviolet and visible light while preserving near-infrared transmission, ideal for solar simulation chambers. The DBT series bandpass filters—DBT400 to DBT740—offer customizable center wavelengths and bandwidths, with DBT660 being widely used in facial recognition systems due to its compatibility with infrared cut-off filters. Our neutral gray glass (ZAB00–ZAB70) provides uniform attenuation across the visible spectrum, making it perfect for photography ND lenses and laser power control. High borosilicate glass windows (up to 750×1200mm) serve as heat-resistant substrates for high-temperature environments like microwave ovens and chemical reactors. Moreover, we produce quartz glass (JGS1–JGS3) and colorless optical glass (BK7, B270) for ultra-high purity and low dispersion needs. Every product is manufactured in our 3,500㎡ factory equipped with internal slicing, grinding, and polishing lines. Customization is a core strength—whether it’s thickness tolerance within ±0.1mm, surface quality to 60-40 standard, or special coatings like anti-reflective or hard film layers. Clients such as Ouyase Water Art and Jiangsu Yaocheng Glass Products rely on our flexibility and precision, proving that Jingsheng Optics delivers not just products, but engineered solutions.
--- Quality Assurance and Certifications ---
• ISO9001 Quality Management System:
At Jingsheng Optics, quality is not an afterthought—it’s embedded in every stage of production. Our ISO9001 Quality Management System certification reflects our unwavering commitment to excellence, traceability, and continuous improvement. From raw material sourcing to final inspection, each process is documented, monitored, and audited to ensure consistency and compliance. For example, when producing DBT660 bandpass filters, we maintain strict control over coating deposition parameters via IAD technology, ensuring peak transmittance ≥90% and cutoff transmittance <0.1% across specified bands. Every batch undergoes spectral testing using calibrated spectrophotometers, and results are cross-referenced with customer specifications. Our internal QC team performs visual inspections for bubbles, stripes, and stress levels—rated at C-B/3C or better per international standards. Furthermore, all products pass environmental stress tests, including thermal cycling and humidity exposure, validating their suitability for harsh conditions. This rigorous approach has earned us recognition as a Top 10 Supplier by Jiangsu Sanlian Biological Factory (2023 & 2024) and an Excellent Supplier designation from Endershaus (Suzhou). Our certified processes also support rapid prototyping and short lead times—key advantages in fast-paced R&D environments.
