--- Factors Influencing the Pricing of Cutoff Optical Filters ---
• Material Quality and Specifications:
The cost of cutoff optical filters is heavily influenced by the quality and specifications of the raw materials used. High-grade optical glass such as BK7, K9, and quartz glass—materials known for their exceptional transmittance, thermal stability, and low absorption—significantly impact pricing. For instance, Nantong Jingsheng Optical Instrument Co., Ltd., a trusted manufacturer based in Jiangsu Province, produces its cutoff filters using first-class optical glass substrates, including imported ultra-thin glass for enhanced performance. Their DBT660 bandpass filter glass, with a center wavelength of 660±2nm and peak transmittance exceeding 90%, is manufactured using ion-assisted deposition (IAD) dielectric hard coatings, ensuring spectral stability and durability under harsh conditions. The material’s ability to withstand MIL-STD-810F environmental testing further justifies higher pricing. Additionally, precision in thickness tolerance (±0.1mm), surface accuracy (λ/2 or better), and customization options like circular (4–70mm) or square (2–70mm) shapes increase production complexity and costs. However, these premium features are essential for applications in aerospace, medical diagnostics, and laser rangefinders, where reliability cannot be compromised. Therefore, while lower-cost alternatives may exist, investing in high-specification materials ensures long-term performance and reduces system failure risks—making material quality not just a cost factor, but a strategic investment.
--- Overview of Cutoff Optical Filter Products ---
• Popular Brands and Their Features:
Among the most sought-after cutoff optical filters in the market is the DBT660 bandpass filter from Nantong Jingsheng Optical Instrument Co., Ltd., branded under the Jingsheng Optics name. This product stands out due to its precise center wavelength of 660±2nm, a half-width at half-maximum (FWHM) ranging from 30–100nm (customizable), and an outstanding peak transmittance of ≥90%. Its cutoff performance is exceptional: transmittance drops below 0.1% in both the shortwave (350–625nm) and longwave (700–1100nm) bands, making it ideal for filtering stray light in laser rangefinders and infrared sensors. The filter is fabricated using high-purity BK7 or quartz glass substrates and coated with IAD-deposited dielectric hard films, which provide excellent resistance to abrasion, humidity, and temperature fluctuations. Another standout product is the HWB4 infrared transmission visible absorption glass, designed to block visible light (400–700nm) while allowing selective infrared transmission (700–2500nm). This makes it indispensable in night vision devices and medical imaging systems. The ZAB50 neutral gray glass, offering ~50% uniform transmittance across the visible spectrum, is widely used in photography and laser intensity control. Each product is backed by ISO9001 certification and meets stringent quality standards, reinforcing Jingsheng Optics’ reputation as a reliable supplier in scientific and industrial optics.
