LASER COMPONENTS offer specialised thin film coatings from MSO Jena who provide specialised and specific thin film coatings for most requirements utilising development of thin film design, which is essential in the manufacturing process.
Through the use of plasma-ion assisted deposition (PIAD) virtually water free, amorphous coatings can be produced, resulting in hard and durable coating layers with low losses, achieved with near the ideal packing density of one. Substrates do not need additional heating for PIAD coatings as the heat needed occurs naturally during e-beam evaporation and from the plasma source, which is at approximately 100°C.
MSO Jena have also developed a way to coat very small areas on substrates, down in the micron (pixel) range, using their photolithographic micro-patterning system. A photoresist is applied to the whole area and the region where the coating is required is exposed using a mask, and then the resist removed. The coating is then applied, which adheres only to the areas where the resist has been removed. The whole process can be repeated producing new shapes with different coating types. This by no means restricts the thin film design itself, and in this way several micro patterned layers on the surface form arrays of interference filters.
