The "Neutral Density Filter" is a filter with a flat spectral transmittance in the visible range. It is suitable for controlling the intensity of light without selectively absorbing the energy of specific wavelengths, making it ideal for adjusting exposure during color photography and for regulating light levels in various measurement instruments. Due to variations in spectral characteristics depending on the melting conditions, care is taken to maintain the specified performance by adjusting the thickness. Therefore, by differentiating the types of products and adjusting the thickness, it is possible to create combinations of filters with any average transmittance. 【Features】 ■ Flat spectral transmittance in the visible range ■ Controls light intensity without absorbing energy at specific wavelengths ■ Used for exposure adjustment in color photography and light level regulation in various measurement instruments ■ Maintains specified performance by adjusting thickness ■ Capable of creating combinations of filters with any average transmittance *For more details, please refer to the PDF document or feel free to contact us.

The "Color Temperature Conversion Filter" is a filter that has a smooth upward or downward sloping transmission curve in the visible range. It is used for color temperature conversion of light sources or for adjusting color temperature during shooting. By adjusting the thickness of the polished material, filters with any desired color temperature conversion capability can be created. When the color of a light source visually compares to the color of a perfect black body heated to a certain temperature, and is the same or very similar, the temperature of the perfect black body is referred to as the color temperature. The reciprocal of the color temperature multiplied by 106 is taken as a unit, called the "mired," and is used as a unit to express color temperature conversion capability. 【Features】 ■ Filters with any desired color temperature conversion capability can be created by adjusting the polished thickness. ■ Used for color temperature conversion of light sources or for adjusting color temperature during shooting. ■ No angle dependency due to the angle of incidence. ■ No change in transmission and absorption wavelength characteristics. ■ Even relatively large glass substrates can be cut to any size through post-processing. *For more details, please refer to the PDF document or feel free to contact us.

The "green filter" is a filter that transmits a relatively narrow band of wavelengths centered around the green wavelength range. It is named after the wavelength at which its transmittance is at its highest. If you want to achieve maximum transmittance at a specific wavelength or absorb wavelengths below a certain point, this can be accomplished by bonding these filters with sharp cut filters. It is used as a contrast effect filter in black and white photography, as well as a green filter for tricolor decomposition. 【Features】 ■ Transmits a relatively narrow band of wavelengths ■ Used as a contrast effect filter in black and white photography ■ No angle dependence due to the angle of incidence ■ No change in transmittance/absorption wavelength characteristics ■ Can be cut to any size through post-processing, even with relatively large glass substrates *For more details, please refer to the PDF document or feel free to contact us.

The "Sharp Cut Filter" blocks as much light as possible below a certain wavelength while allowing longer wavelengths to pass through as completely as possible, within the wavelength range of 350nm to 800nm. There are 15 types ranging from L-37 to R-66, where the symbols L, Y, O, and R represent the color tone of the filter, and the two-digit numbers indicate the transmission limit wavelength. The filters from L-42 to R-66 are "color glass," and by adjusting the color temperature, it is possible to change the spectral characteristics to some extent. 【Features】 ■ Ability to change spectral characteristics by adjusting color temperature ■ JIS B7113 (Sharp cut glass filter for photography) ■ No angle dependence due to incident angle ■ No change in transmission and absorption wavelength characteristics ■ Relatively large glass substrates can be cut to any size through post-processing *For more details, please refer to the PDF materials or feel free to contact us.
