Absorptive Neutral Density Filters-Unmounted
Absorptive ND filters are one of simple beam attenuators to be used to control the amount of light. The amount of light is controlled by distributing a light absorbing substance in optical glass.

Reflective Neutral Density Filters-Unmounted
The amount of incident light is controlled by the thickness of the chromium coating. A part of the light is transmitted, and the rest is reflected or absorbed by the coating.
Reflective Neutral Density Filters-Mounted
This reflective neutral density filters are mounted in adaptor ring, which can be uesd with our existing filter holder.
Variable Reflective Neutral Density Filters
Variable reflective neutral density filters are used to change the amount of light continuously by rotating the filter or moving the light source.
Variable Reflective Neutral Density Filters-Aluminium Type
This variable neutral density filter allows conrolling the transmittance by letting a number of uncoated spots spread on the surface of the aluminum coated filter.
Stepped Neutral Density Filters
Variable reflective neutral density filters are used to change the amount of light continuously by rotating the filter or moving the light source.
Ground Glass Diffusers
The front surfaces of ground glass diffusers are frosted glass by abrasive sands and the other surfaces are polished. Roughness and transmittance become finer and larger as the grid size increases.
Opal Glass Diffusers
Opal glass diffusers are made of milk-white glass, which are mixed light scattering substance.
Short Wave Cutoff Filters
Elements controlling the wavelength of transmitted light by a light-absorbing substance blended in the glass. Filters absorbing light with a wavelength of a particular value or shorter and transmitting light in the longer wavelength region.
UV transmitting Filters
Elements controlling the wavelength of transmitted light by a light-absorbing substance blended in the glass. Filters transmitting ultraviolet light, absorbing visible light, and transmitting some near-infrared light.
IR Transmitting Filters
Elements controlling the wavelength of transmitted light by a light-absorbing substance blended in the glass. Filters absorbing most visible light and transmitting infrared light.
Near IR Absorbing Filters
Elements controlling the wavelength of transmitted light by a light-absorbing substance blended in the glass. Filters transmitting visible light and absorbing near-infrared light.
Heat Absorbing Filters
Elements controlling the wavelength of transmitted light by a light-absorbing substance blended in the glass. Filters transmitting visible light and absorbing infrared light.
Blue Glass Filters
Elements controlling the wavelength of transmitted light by a light-absorbing substance blended in the glass. Filters absorbing only the visible light in the longer wavelength region and transmitting light in the other wavelength region.
Green Glass Filters
Elements controlling the wavelength of transmitted light by a light-absorbing substance blended in the glass. Filters absorbing the light in the near-infrared region and transmitting light in the other wavelength region.
Dichroic Mirrors
Filters transmitting the light with a wavelength of a particular value in the visible region and reflecting the light of other wavelengths. The dielectric film features virtually no light absorption.
Dichroic Filters
Filters transmitting the light with a wavelength of a particular value in the visible region and reflecting the light of other wavelengths. The dielectric film features almost no light absorption.
Cold Filters
Wavelengh selection filters for heat rays, with a dielectric film coated on heat absorbing glass. Transmits visible light, and reflects and absorbs near-infrared light.
Cold Mirrors
Wavelength selection mirrors for heat rays, with a dielectric film coated on heat absorbing glass. Reflects 90% or more visible light, and transmits 80% or more near-infrared light.
Interference Filter
"VPF series is a filter made of dielectric coating on flat substrate." With an applying the reflected beam of interference phenomenon on the surface of thin film interface to achieve a selective certain bandwidth of wavelength.
Narrowband Interference Filters
Element emitting light at an arbitrary wavelength, by using the light interference caused by a dielectric film and a metallic film coated on the glass substrate.
