Glass filters suitable for various applications such as imaging equipment and medical devices are featured!
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.
For light sources such as infrared alarms and night vision devices! Color glass filters that transmit infrared wavelengths.
The "infrared transmission filter" is a filter that absorbs almost all visible light and transmits infrared light. There are "R series" and "IR series" that cut the infrared range relatively sharply, and "RM series" that cut the infrared range gradually. They are widely used as light sources in infrared alarm systems and night vision devices. 【Features】 ■ Absorbs almost all visible light and transmits infrared light ■ No angle dependence due to the angle of incidence ■ No change in transmission and 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.
A filter that transmits a relatively narrow band of wavelengths centered around the green wavelength range.
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.
Used for sensitivity correction of exposure meters! A filter that selectively absorbs infrared and near-infrared light.
The "Color Correction Filter" is a filter that adjusts the color light of the blue, green, and red parts of the visible spectrum, and there is a cyan series. The "Cyan Filter" is a filter that selectively absorbs the red and near-infrared parts, with no fading due to the light source, and is used for image tube sensitivity correction, exposure meter sensitivity correction, and so on. 【Features】 ■ Selectively absorbs the red and near-infrared parts ■ No fading due to the light source ■ Used for image tube sensitivity correction, exposure meter sensitivity correction, etc. ■ No change in transmission and 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.
Control the intensity of light without absorbing energy at specific wavelengths!
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.
Prevention of destruction due to rapid heating and cooling! Glass filter that absorbs heat rays.
The "heat ray absorption filter" is a somewhat bluish filter glass that has a high transmittance in the visible range and absorbs heat rays (infrared rays). "HA-30" and "HA-50" are phosphate glasses that absorb heat rays emitted from light sources very well, making them particularly effective for slide projectors and various lighting fixtures. To prevent the breakage of filter glass due to rapid heating and cooling, we can also supply tempered glass using thermal strengthening methods. 【Features】 ■ High transmittance in the visible range and absorbs heat rays (infrared rays) ■ Used in slide projectors and various lighting fixtures ■ Prevents breakage due to rapid heating and cooling ■ Tempered glass can also be supplied *For more details, please refer to the PDF materials or feel free to contact us.
Used for wavelength calibration, it serves as a dichroic filter! It significantly absorbs specific wavelengths.
The "Wavelength Calibration Filter" is used for wavelength calibration as a dichroic filter. V-10 and V-30 contain neodymium, while HY-1 contains holmium, significantly absorbing specific wavelengths. 【Features】 ■Significantly absorbs specific wavelengths ■V-10 and V-30 contain neodymium ■HY-1 contains holmium ■Used for wavelength calibration as a dichroic filter *For more details, please refer to the PDF document or feel free to contact us.
