50x50mm Metallic VIS-NIR ND Filters

 50x50mm Metallic VIS-NIR ND Filters

Product name : 50x50mm Metallic VIS-NIR ND Filters
Description :
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.

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
