功能

• This filter is used to reduce the redness of reddish light such as tungsten lamps (LB) or to reduce the blueness of bluish light such as LED light sources (LA).
• You can use this function when you want to observe a sample with a natural color without being affected by the light source.
• It can also be used as a filter for cameras that do not have white balance.
• It can be used as a filter to change the color temperature of a light source in experiments such as chromaticity measurement.
• * Since the transmittance wavelength characteristic is given priority, the filter thickness is adjusted to satisfy the transmittance performance.
• * For this reason, the thickness of each filter will vary.
• * Anti-reflection coat is not applied on both sides.
• * Reflected light from the front and back causes a transmittance loss of about 10%.
• Placing the filter near a light source can cause the filter to break due to sudden changes in temperature.
