Human eyes can only pick up a small segment of the wavelength spectrum. In some industries, such as metrology or medicine, invisible yet high intensity wavelengths are used. These can be damaging to the human eye, so suitable filters are required. Materion Balzers Optics manufactures these filters, catering to specific wavelengths and applications. Our filters provide safe light blocking in accordance with the applicable standards. We can even ensure protection against laser systems with high energy outputs.
