Product description
BF33 (Borofloat 33) by ZMSH is a type of heavy flint glass that is
commonly used as a substrate material in various optical
applications. It is known for its high refractive index and low
dispersion, which makes it useful for applications that require
high light focusing and power density. BF33 is made from a
borosilicate glass, which has a low coefficient of thermal
expansion and high resistance to thermal shock. This makes it an
ideal substrate for high-temperature processing and for use in
harsh environments. BF33 is commonly used in applications such as
laser mirrors, beam splitters, and optical lenses, among others.
The exact properties and characteristics of BF33 will depend on the
manufacturer and the specific production process used to make it.

WAFER FABRICATION PROCESS
Shape Cut
Thin sheets are scribed, thick sheets are water jetted and blocks
are wire sawn to begin the process with a wafer "blank".
CNC Edge
Each wafer is individually edged on a Precision CNC Edge Grinding
Station.
Lapping
As required, wafers are lapped to precise thickness or flatness.
Polishing
Double-side Commercial Polish removes subsurface damage and Super
Polish creates a pristine finish.
Cleaning
We combine ultrasonics and megasonics on multiple cleaning lines
which feed directly into a Class 100 Clean Room.
Inspection
In our Class 100 Optical Clean Room, we inspect to various quality
levels under the appropriate lighting conditions.
Packaging
All wafers are packed in pre-cleaned containers, double bagged and
vacuum sealed within the Class 100 Clean Room.
