A brief History of the Starna Group
The wide variety of Starna® products on this web site are manufactured in the Optiglass factory founded in 1964, whose lineage of optical expertise is traceable to the early part of the last century.

In the 1950s, the founders of Optiglass developed and perfected the technique of fully fusing component parts by heat alone, without the distortion of optical surfaces. This major advance transformed the design and production of spectrophotometer cells and associated products. Continual development and improvement is reflected in the high quality world class Starna® products illustrated on this site.

All manufacturing processes are carried out in our ISO 9000 certified production facility, from the design and development of products through to customised production machinery. The unique blend of skills including: cutting, slicing, grinding, polishing, conventional drilling, ultrasonic drilling and fusing
as well as metallic, multi-layer and anti-reflection coating in one of many coating plants, achieves a complete vertically integrated process.

During manufacture of all component parts, special care is taken to avoid contamination by the use of stringent cleaning processes. Together with mandatory inspection procedures these stringent cleaning processes ensure that all products leave the factory in a pristine contamination-free condition, with an unconditional guarantee against faulty workmanship. This special treatment of cells also reduces bubble adhesion, which is of particular importance in flow cell applications.
