An Introduction to the Optics Manufacturing Process

Oct 31, 2008· Molded optics are a common way to produce small lenses in high volume. A molded optic starts as a preform, which is a ball or disc that has already been polished to very high quality. It is then shaped in a mold at high temperatures. The overview of this process can be seen in Figure 9. Figure 9: Overview of the Molding Process (Schott)

Automatic Polarimeter

Apart from the standard supply of 100 mm and one 200 mm sample tubes, a choice of circulating temperature controlled other sample tubes are available which can be supplied with the instrument as additional accessories. Data transfer to Pen Drive through USB Port.

Failure Analysis

The reflected optical data from each single scan point is interpreted by the interferometer as an interference pattern and recorded as a depth profile (A-Scan). By scanning the probe in a linear fashion across the sample, a cross-section (B-scan) is obtained. 3D volumetric images can be generated by combining multiple cross-sections.
