Absorptive ND Filter OD 2.0 | 400-700nm, 1% Transmission

Absorptive ND Filter OD 2.0 | 400-700nm, 1% Transmission

The OPTOStokes Absorptive ND Filter OD 2.0 delivers uniform, broad-spectrum beam reduction across the 400–700 nm visible region. Engineered with high-stability optical glass, this filter provides precise optical attenuation by absorbing excess photon energy rather than reflecting it back into the optical path, effectively eliminating unwanted secondary interference and ghosting in sensitive optical systems.

Technical Specifications

Primary Applications

Designed for multi-purpose optical power management, these absorptive nd filters are ideal for:

• Spectrophotometry & Spectroscopy: Calibrating intensity scales and extending dynamic range in analytical spectrophotometers.

• Detector Protection: Preventing saturation and permanent exposure damage in sensitive sensors (CCD, CMOS, photodiode arrays).

• Laser Power Control: Attenuating visible laser sources without generating back-reflections into laser cavities.

Customization & Engineering Support

OPTOStokes maintains an extensive selection of off-the-shelf catalog inventory for immediate prototype validation. For OEM integration, we supply customized geometries (round, square, custom polygon CNC shaping) and precision mounting rings (aluminum or stainless steel). Every component undergoes rigorous spectrophotometric inspection to ensure precise transmission compliance and batch-to-batch repeatability.
