Kodak Wratten 2 Neutral Density Filters are used in image forming optical systems to reduce light intensity
across the visible spectrum without altering the spectral profile. These ND filters feature tolerances of ±10% of
the nominal diffuse density. Although Kodak Wratten 2 Neutral Density Filters transmit the infrared spectrum,
neutrality is controlled only in the visible spectrum. All ND filters are 0.1mm in thickness. Note: Storage in
humid environments can cause the filters to cloud and temperatures should not exceed 50°C for extended
periods. Every 0.3 density increment equals one f-stop. Kodak Filter No. 96. All filters are 0.1mm thick. Kit
#15-115 includes all 13 Optical Densities.

These neutral density filters are continuously variable over 270° of the filter. Circular variable
filters
provide
linear attenuation
of incident
light by rotating
the filter. Designed
to be spectrally
flat from 400 to 700nm, they
provide
excellent
attenuation
for spectrometers
and other optical
instruments.
The 50mm diameter filters are
available mounted or unmounted. The durable anodized aluminum mount has an indicator arrow that accurately
identifies the angular position of the filter for increased repeatability. The 360° rotating mount comes
complete with 4" L, 0.5" diameter stainless steel post.

• Complete Package
• Smooth Rotation
Circular ND filters provide continuously
variable,
linear
attenuation
of light by rotating
the filter about its
center. Transmitted
intensity
varies as a function
of
the optical
density range. An inexpensive,
ergonomic
Delrin® hub assembly
holds the glass filter
securely to
the mount block, ensuring
a protective
surface
against
the filter.
A 1/4-20 tapped hole in the aluminum
mount
block permits a variety
of mounting
configurations.
The filter
is rotated
manually by turning
along the outside
edge, front knob, or rear turning screw. A 4" long,
0.5" diameter
stainless
steel post is included.
