[\/vc_column_text][\/vc_column][\/vc_row][\/vc_section][vc_section css=”.vc_custom_1759402213642{background-color: #FFFFFF !important;}”][vc_row][vc_column width=”2\/3″][vc_column_text css=””]Specially formulated adhesives are available for imprint replication of refractive lenses and diffractive optical elements (DOEs). These adhesives are suitable for micro- and nano-imprint lithography (NIL), wafer level optics, and wafer bonding. These adhesives can be easily applied via puddle dispensing, spin-coating or jetting. They offer excellent adhesion to commonly used grades of glass wafers and upcoming new polymer substrates including optical grade PET or PC. Once applied and imprinted, they are quickly cured with UV light, creating a precise and durable structure on the wafer.[\/vc_column_text][vc_column_text css=””]Highly complex optical geometries can be produced through the targeted, two-dimensional bonding of several such structured wafers with each other \u2013 and, if necessary, with so-called spacer wafers as precise spacers; this bonding technique is known as wafer bonding. Hoenle has developed customized adhesives for this purpose, which are characterized by high optical quality, reliable curing in thin layers, as well as excellent mechanical properties in combination with different materials such as glass, epoxy, and metal-based masking layers.[\/vc_column_text][vc_column_text css=””]Hoenle also offers black UV-curing adhesives for black coatings and optical edge sealing. These black epoxy adhesives are permeable to UV light when uncured. After curing, they are opaque and impermeable to light.[\/vc_column_text][\/vc_column][vc_column width=”1\/3″][vc_single_image image=”1728″ img_size=”full” add_caption=”yes” css=””][vc_column_text css=””]Nanostructures are printed in a very thin layer of adhesive on a glass wafer<\/p>\n
