A. It is same size in square that fits in the maximum lens size (diagonal length of 150mm).

Q. What is the minimum size of a cell?

A. It is approximately 2mm 3mm. (It varies by the shape, optical axis, etc. Please consult with us. )

Q. What is the maximum lens curvature?

A. It is about 100mm. (It varies by the shape, optical axis, etc. Please consult with us. )

Q. What is the minimum lens curvature?

A. It is about 0.3mm. (It varies by the shape, optical axis, etc. Please consult with us. )

Q. Is it possible to set a cell at an off set angle?

A. Yes, it is possible. Please consult with us for details.

Q. What types of the coatings are available?

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).

Q. What types of the glass materials are available?

A. White crown and the Pyrex are the standard glass types.

Q. Can you temper the glass?

A. Yes, it is possible. Please ask us for details.

Q. Is the other side of lens array plano only?

A. We grind and polish the other side. We can finish to your choice of concave, convex, cylindrical as well as plano.

Q. Are all the cells need to be spherical?

A. No, it can be a combinaton of spherical, aspherical and even cylindrical.

Q. Are the cells need to be square?

A. It can also be other shape of your choice. Please consult with us.

Q. What is the maximum size?

A. It is up to 150mm in diameter.

Q. What is minimum size?

A. It is about 10mm in diameter.

Q. What types of the coatings are available?

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).

Q. What types of the glass materials are available?

A. White crown and the Pyrex are the standard glass types.

Q. Can you temper the glass?

A. Yes, it is possible. Please ask us for details.

Q. Is the other side of aspheric lens plano only?

A. We grind and polish the other side. We can finish to your choice of concave, convex, cylindrical as well as plano.

Q. Is the shape of the lens round only?

A. We can fabricate with flange or in odd shape as you wish. Please consult.

Q. What is the maximum size?

A. It is approximately 300mm squares with about 10mm thickness. It varies by the glass. Please consult with us.

Q. What is the minimum size?

A. It is about 5mm in diameter with 0.5mm thickness.

Q. Who melts the glass?

A. We melt our own glass using our original ingredients that have been developed by our team of engineers.

Q. Can you apply coating to it?

A. Yes, we can.. For surface protection MAR (anti-reflection coating) is usually applied.

Q. What types of the coatings are available?

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.

Q. Can you supply a filter that is not listed in the catalog.

A. We melt the glass for our filters. Please consult your requirements with us.

Q. How different is it from the filters made with multilayer coatings?

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.

Q. Is it an absorption filter or a reflective type?

A. It is an absorption type filter. We can combine the absorption type filter with the reflective type.
