Product Description
- Uncoated: 1.0 μm-2.6 μm
- Attenuating low power lasers
- OD: 0.3, 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, 5.0, 6.0
- Absorptive neutral density filters
LBTEK Near-IR (NIR) Absorptive Neutral Density (ND) Filters, also known as NIR DN filters, offer optical densities (OD) ranging from 0.3 to 6.0 and operate in the 1.0-2.6 μm wavelength range. Effective attenuation within this range is widely used in infrared laser processing, infrared sensing, optical communications, and other fields. The LBTKE filter is circular and Ø25.4 mm in size, with thickness dependent on the material. The Ø25.4 mm filter can be directly mounted on a 30 mm coaxial mounting plate for use in 30 mm coaxial systems. LBTEK also offers filters mounted in standard SM1 tubes for convenience. LBTEK also offers custom filters with other special sizes and optical densities. Please contact Technical Support for inquiries.
Near-IR (NIR) Absorptive Neutral Density (ND) Filters, Mounted
- Mounted in mechanical housing, removable
- Uncoated: 1.0 μm -2.6 μm
- Low power applications
LBTEK Near-IR (NIR) Absorptive Neutral Density (ND) Filters are made of neutral filter glass with stable absorption in the 1.0 μm - 2.6 μm wavelength range, featuring optical density (OD) values of 0.3-6.0 and a size of 1 inch. The MNDFA series of absorbing neutral density attenuators come mounteded in detachable standard lens tubes, with the product model, working wavelength, and OD value engraved on the surface for easy identification by users.
