Lasertec develops many types of filters using advanced IBS technology. These filters can be used world-wide in medical equipment and laser products. We use advanced IBS“hard”coating to deposit on a single, flat substrate. Traditional coating techniques use multiple substrates laminated together. Multiple laminations usually have some wedges on them which causes imaging problems and misalignments. In addition, traditional coatings are“soft”and need glass protection. Differences: The hard coated, single substrate filters provide the ultimate performance, environmental stability, easy handling, and long life durability.
