功能

• This holder replaces a filter inserted into the optical axis by attaching multiple filters to the revolver and rotating the revolver.
• ND filters with different transmittance can be installed to adjust the amount of transmitted light, and color filters can be installed to switch the transmission wavelength.
• A single type (NDWH-15 S) that can be switched in 6 steps and a double type (NDWH-15 W) that has 2 sets of 6 steps are available.
• You can choose from two types: fixed (NDWH-15 S/NDWH-15W) and rod type (NDWH-15SRO/NDWH-15WRO).
• The revolver has an index (where it stops rotating) every 30 degrees.
• You can use this index to pin the filter to 0, 30, 60, or 90 degrees.
• The revolver has an index (where it stops rotating) every 30 degrees.
• You can use this index to pin the filter to 0, 30, 60, or 90 degrees.
• The index filter holder does not contain an ND filter.
• Select from the ND filter (AND-15 C/FND-15C02).
• A rotary variable reflection ND filter holder (NDHN) is also available that can continuously change the amount of transmitted light.
• * If there is a filter at the bottom of the revolver, the holder supports will get in the way and light cannot pass through.
• * All indexes except this position allow light to pass through.
• * A special tool is required to remove the filter case.
• * When removing the filter case and using a φ25.4 mm filter, a screw ring (RR-25.4-5) and a resin ring (DR-25.4-5) are required.
• * The rod type must be offset from the optical axis.
• * The amount of offset depends on the position of the revolver hole used.
