COMMERCIAL GRADE METALLIC NEUTRAL DENSITY FILTERS VIS-NIR (400-2000nm)
Neutral density (ND) filters are useful in a number of applications such as attenuators for broadband spectral sources, partial reflectors for light balancing applications and for use as neutral beamsplitters. Metallic type neutral density filters obtain their optical density by depositing a metal alloy coating onto a specific type of substrate which is determined by the wavelength region of interest. Float Glass substrates available in custom sizes.
BENEFITS
- Provides attenuation with greater linearity over a wide spectral range
- Reduces thermal effects in low-power laser applications
- Delivers superior durability
COMMON APPLICATIONS
- Calibration
- Attenuation
- Low-power lasers
- Scientific measurements and research
- Machine vision & other imaging
Optical density (OD) is defined as the logarithm to the base 10 of the reciprocal of the transmitted radiant power (T):
