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. Alternatives to BF33 (Borofloat 33) glass substrate include: BK7 glass substrate Fused Silica Sapphire Zerodur Corning Willow Glass Alumina

Specification

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.
