Silicon based devices such as MEMS, CCD/CMOS sensors or
LCOS microdisplays are packaged with cover glasses. These
cover glasses consist of clean surfaces plus functional coatings
- such as AR coatings, NIR blocking filters or index matched
ITO. Where needed chrome apertures can be provided, as well
as solderable frames, B-stage epoxy frames or soldered Kovar
lids as packaging solutions. Depending on the final application
the choice of material can be very important. Optics Balzers has
experience with coatings on a broad variety of glass substrates,
such as borosilicate, filter glasses, sapphire, etc.
A key factor of Optics Balzers' sensor lids is the superior low
defect properties of the coatings as they define the quality of the
device. Sealing or bonding solutions for the subsequent assembly
process are an integral part of the products offered.
Some sensor applications have less stringent defect requirements
and solutions can be provided with the same functionality
but with a cost-effective adjusted quality performance.
