[Features]
· Using an ND filter that changes the optical density at regular intervals, the transmitted light quantity can be switched in stages.
· It can be used for the calibration of densitometers and calorimeters.
· Since 11 stages of optical density are arranged in regular intervals on one piece of glass, approximate optical density values of unknown optical density samples can be recognized visually.
· Can also be used for light intensity adjustment of laser beam as it is chromium-coated.
· As it is chromium coated, even if wavelength is changed in the visible light range, optical density will not change.
· * The range of uniform transmittance is 4.6 x 25 mm.
· * Use the product with a beam of φ3 mm or less.
· * The transmittance changes logarithmically according to the movement distance.
· * Not proportional.
· * Cannot be used with high energy pulsed laser.
