Ø50mm Metallic UV-VIS-NIR ND Filters
Ø50mm Metallic UV-VIS-NIR ND Filters
產品名稱 : Ø50mm Metallic UV-VIS-NIR ND Filters
產品說明 :
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
