Reflective Filters: reflect the undesired wavelengths while transmitting the remaining ones
Monochromatic Filters allow a limited range of wavelength to pass
Neutral Density (ND) Filters are utilized to reduce the intensity of light by reflecting or absorbing a percent of light at specific wavelengths
