BK7 Glass Encoder Scales
BK7 is a high quality optical glass that is usually used when the extra advantages provided by fused silica are not required. BK7 performs well in all chemical tests, so no additional or special handling is needed, which in turn reduces the costs of manufacturing. It is a relatively hard material with extremely low bubble and inclusion content.
