Thorlabs NE05A Absorptive Neutral Density Filter

Enhance your optical setup with the Thorlabs NE05A Absorptive Neutral Density (ND) Filter, designed to attenuate light across a broad spectrum without altering its wavelength distribution. Featuring a 25 mm diameter and a precisely engineered optical density of 0.5, this filter reduces light intensity to 31.6% of its original value, making it ideal for laser applications, spectroscopy, and photonics experiments.

Key Features:

• High-Quality Absorptive ND Filter: Maintains uniform attenuation with minimal beam distortion.
• SM1-Threaded Mount: Designed for easy integration into standard Thorlabs optomechanical assemblies.
• Optical Density of 0.5: Ensures precise light attenuation for sensitive optical applications.
• Durable Construction: Built for reliability and long-term performance in laboratory environments.

Specifications:

• Optical Density (OD): 0.5
• Diameter: Ø25 mm
• Mount Compatibility: SM1-threaded (1.035″-40 TPI)
