Neutral Density Filter, Anti-Reflection Coating 700 nm-1100 nm, Unmounted — Model NDFA20-03-B

Operating wavelength 700 nm-1100 nm, ØØ50 mm.

Product Description

  • Absorption-type Neutral Density Attenuator
  • Anti-reflection Coating: 700 nm-1100 nm
  • OD: 0.1-6.0
  • Low Power Applications

LBTEK absorptive neutral density filters utilize a high-performance neutral density glass substrate, with an anti-reflection coating applied to one side of the substrate (specifications: Ravg < 0.5% @ 700-1100 nm). These absorptive neutral density filters not only exhibit stable absorption characteristics within the 700-1100 nm wavelength band but also effectively reduce internal light reflection within the product, making them suitable for various low-power laser energy attenuation applications. The product is currently available in 17 optical density specifications (OD 0.1-6.0) and 3 size options (Ø12.7 mm, Ø25.4 mm, Ø50 mm), which can fully meet diverse experimental requirements. Among them, the circular absorptive neutral density filters are also offered in a mounted version (MNDFA series), where the products are pre-installed in standard lens barrels of corresponding sizes (supporting disassembly). Furthermore, LBTEK can provide custom services for filters with specific sizes and optical density values. For customization inquiries, please feel free to contact technical support.
