Reflective Neutral Density Filter, Round, Mounted — Model MNDFR05-20

Operating wavelength 350 nm-1100 nm, ØØ12.7 mm.

Product Description

  • Substrate Material: N-BK7
  • Working Wavelength: 350 nm-1100 nm
  • OD: 0.2, 0.3, 0.4, 0.5, 1.0, 2.0, 3.0, 4.0
  • Low Power Applications
  • Reflective Neutral Density Filters

LBTEK Reflective Neutral Density (ND) Filters are made of N-BK7 substrate with chrome-nickel-iron alloy coating, available in optical density (OD) ranges from 0.2 to 4.0. The sizes include Ø12.7 mm, Ø25.4 mm, and 50.8 mm×50.8 mm. LBTEK filters can be mounted on threaded tubes or coaxial mounting plates for use in coaxial systems, or installed in free space. LBTEK also offers customization services for other special sizes and optical density value attenuators. Please contact Technical Support for any requirements.

Reflective Neutral Density Filter, Round, Mounted

  • Substrate Material: N-BK7
  • Working Wavelength: 350 nm-1100 nm
  • Low Power Applications
  • Reflective Neutral Density Filters
  • Mounted in mechanical housing, detachable

LBTEK round mounted reflective neutral density filters cover an optical density (OD) range of 0.2-4.0, with optical component sizes of Ø12.7 mm and Ø25.4 mm. By depositing chromium-nickel-iron alloy (single-sided) on an N-BK7 substrate, a smooth OD curve is achieved within the 350 nm-1100 nm wavelength range. Although classified as reflective neutral density filters, the chromium-nickel-iron alloy coating still absorbs some incident light. For optimal performance, it is recommended that incident light enters from the side with the chromium-nickel-iron alloy coating. Additionally, care should be taken to avoid contact with this unprotected metal coating, as touching may scratch the uncoated surface. When cleaning, the use of an air blower is advised. The MNDFR series reflective neutral density filters come mounted in detachable standard lens tubes, with the surface engraved with product model, working wavelength, OD value, and other parameters for easy identification for users.
