Product Brand: SIGMAKOKI CO., LTD.
Features
- You can *** an ND filter that varies the optical density at equal intervals to cycle through the transmitted light levels.
- Can be ***d for calibration of densitometers and colorimeters.
- Beca*** 11 levels of evenly spaced optical density are arranged on a sheet of glass, a visual comparison can provide an approximate optical density value for an unknown optical density sample.
- Since it is chrome coated, it can also be ***d to adjust the amount of light of the laser beam.
- Since it is chrome coated, the optical density does not change even if the wavelength changes in the visible light range.
- * The uniform transmittance range is 4.6×25 mm.
- * Use with a beam of φ3mm or less.
- * Transmittance varies logarithmically with the amount of movement.
- * This is not a proportional relationship.
- * Cannot be ***d for high energy pulsed laser.
