The colored glass filter is made of fine-quality colored optical glass. Its advantages are high transparency, thin grinding thickness, will not change the focal point of the lens, and strong ability to absorb and pass various colors. Even if it is heated or damp, the color remains unchanged. In modern photography, this kind of color filter is commonly used. However, due to the color modulation process of colored optical glass, its various pigment levels are not as many as colored plastic films and glass interlayer color filters.
Its main function is to change the color of light, the intensity of light, and the polarization of light, and it can make conscious and quantitative adjustments and controls on the propagation, diffusion, convergence, refraction, absorption, and transmission of the light passing through. So as to make the captured picture achieve the designed image modeling effect.
Optical Filters are used to selectively transmit or reject a wavelength or range of wavelengths. Optical Filters are used in applications such as fluorescence microscopy, clinical chemistry, spectroscopy, or machine vision inspection. Optical Filters are ideal for life science, imaging, industrial, or defense industries.
