--- Why Choose Jingsheng Optics for Cutoff Optical Filters? ---
• High-Quality Materials and Manufacturing Standards:
At Nantong Jingsheng Optical Instrument Co., Ltd., quality is not just a promise—it’s built into every product through rigorous material selection and precision manufacturing. The company specializes in producing high-performance cutoff optical filters using first-class optical glass such as BK7, K9, and quartz glass, ensuring exceptional transmittance and spectral stability. For instance, the DBT660 bandpass filter glass—used in laser rangefinders and biomedical imaging—features a peak transmittance of ≥90% at 660±2nm with a half-width at half-maximum (FWHM) of up to 115nm, while maintaining cutoff transmittance below 0.1% in critical bands like 350–625nm and 700–1100nm. This level of performance is achieved through ion-assisted dielectric hard coating (IAD), which enhances film durability and resistance to environmental stress, verified by MIL-STD-810F compliance. Additionally, all products undergo strict quality control under ISO9001 Quality Management System Certification, ensuring consistency across batches. With a factory covering 3,500 square meters and equipped with internal slicing, grinding, and polishing machines, Jingsheng Optics maintains full process control from raw material to finished product. Their commitment to excellence is reflected in their long-standing partnerships with industry leaders such as Jiangsu Sanlian Biological Factory Co., Ltd., recognized as a Top 10 Supplier in both 2023 and 2024. These certifications and capabilities make Jingsheng Optics a reliable choice for clients demanding precision, reliability, and scalability in optical filtering solutions.
• Customized Solutions for Diverse Applications:
Jingsheng Optics excels in delivering tailored optical filter solutions that meet the exacting demands of diverse industries. One notable example is their collaboration with Endershaus (Suzhou) Automation Instrument Co., Ltd., a key player in industrial automation systems requiring high-precision optical components. In this project, Jingsheng developed custom infrared transmission visible absorption glass (HWB4) with a thickness tolerance of ±0.1mm and selective transmission in the 700–2500nm range, enabling enhanced performance in thermal imaging sensors used in automated inspection lines. Another real-world application involved supplying orange glass (CB580) and neutral gray glass (ZAB50) to Ouyase Water Art (Taicang) Co., Ltd., where precise color temperature control was essential for stage lighting systems. The ZAB50 filters provided uniform light attenuation across the visible spectrum without altering color balance—critical for maintaining visual fidelity during live performances. Furthermore, Jingsheng supports complex customization: from non-standard sizes (e.g., circular diameters from 4–70mm, square up to 70mm) to specialized coatings like anti-reflective or hard films, all based on client-specific wavelength requirements. Their technical team, composed of senior optical engineers, works closely with customers to optimize parameters such as cutoff wavelengths, transmittance profiles, and thermal stability. This flexibility has enabled Jingsheng to serve clients in aerospace, pharmaceuticals, semiconductors, and nanotechnology—proving that their expertise extends beyond standard products into mission-critical applications where performance cannot be compromised.

• Overview of Cutoff Optical Filters:
Jingsheng Optics offers a comprehensive portfolio of cutoff optical filters designed for high-precision applications across multiple sectors. Among their flagship products are UV-blocking glasses (ZJB series), which include models like ZJB220 to ZJB380, engineered to absorb ultraviolet radiation below 380nm while allowing visible light transmission—ideal for protecting sensitive imaging sensors in digital cameras and scientific instruments. Similarly, the red glass (HB600-HB720) and blue glass (QB1-QB26) series provide targeted spectral filtering for fluorescence analysis and medical diagnostics. A standout product is the DBT660 bandpass filter glass, widely used in laser rangefinders and facial recognition systems due to its ability to isolate 660nm signals with minimal interference. Its robust dielectric coating ensures long-term spectral stability even under harsh conditions. The company also produces infrared transmission visible absorption glass (HWB series), such as HWB4, which blocks visible light (<700nm) while transmitting infrared radiation (700–2500nm)—a crucial feature in night vision goggles and thermal imaging devices. For industrial testing and photography, they offer neutral gray glass (ZAB series), with ZAB50 providing exactly 50% transmittance across the visible spectrum, making it ideal for ND lenses in cinematography and laser intensity control. These filters are manufactured using high-purity optical glass substrates with excellent chemical resistance and thermal stability, including high borosilicate glass with a coefficient of thermal expansion as low as 3.3×10⁻⁶/K, suitable for high-temperature environments. Whether for biomedical research, semiconductor fabrication, or security monitoring, Jingsheng Optics’ extensive product line delivers consistent, reliable performance backed by years of R&D and real-world validation.
