A. It is about 5mm in diameter with 0.5mm thickness.
A. We melt our own glass using our original ingredients that have been developed by our team of engineers.
A. Yes, we can.. For surface protection MAR (anti-reflection coating) is usually applied.
A. Single purpose and combination of the coatings are available. Type of coatings are MAR (anti-reflection), UV (ultraviolet rays cutting), and IR (infrared rays cutting). We can also combine the characteristics of the filter with the coatings.
A. We melt the glass for our filters. Please consult your requirements with us.
A. Our filter is an absorption type that has less effect of angle of incidence. It does not have problems due to defects such as pin holes.
A. It is an absorption type filter. We can combine the absorption type filter with the reflective type.
