ARRAY Q&A | LENS ARRAY Q&A |
 |
What is the maximum size? |
|
It is a square that has diagonal length of 150mm. |
|
What is the maximum size of a cell? |
|
|
It is same size in square that fits in the maximum lens size (diagonal length of 150mm). |
|
What is the minimum size of a cell? |
|
|
It is approximately 2mm
3mm. (It varies by the shape, optical axis, etc. Please consult with us.
) |
|
What is the maximum radius? |
|
|
It is approximately 100mm. (It varies by the shape, optical axis, etc. Please consult with us. ) |
|
What is the minimum radius? |
|
|
It is about 5mm. (It varies by the shape, optical axis, etc. Please consult with us. ) |
|
Is it possible to set a cell at an off set angle? |
|
|
Yes, it is possible. Please consult with us for details. |
|
What types of the coatings are available? |
|
|
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). |
|
What types of the glass materials are available? |
|
|
White crown and the Pyrex are the standard glass types. |
|
Can you temper the glass? |
|
|
Yes, it is possible. Please ask us for details. |
|
Is the other side of lens array plano only? |
|
|
We grind and polish the other side. We can finish to your choice of concave, convex, cylindrical as well as plano. |
|
Are all the cells need to be spherical? |
|
|
No, it can be a combinaton of spherical, aspherical and even cylindrical. |
|
Are the cells need to be square? |
|
|
It can also be other shape of your choice. Please consult with us. |

| ASPHERIC LENS / FIRE POLISHED LENS Q&A |
|
What is the maximum size? |
|
|
It is up to 150mm in diameter. |
|
What is minimum size? |
|
|
It is about 10mm in diameter. |
|
What types of the coatings are available? |
|
|
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). |
|
What types of the glass materials are available? |
|
|
White crown and the Pyrex are the standard glass types. |
|
Can you temper the glass? |
|
|
Yes, it is possible. Please ask us for details. |
|
Is the other side of aspheric lens plano only? |
|
|
We grind and polish the other side. We can finish to your choice of concave, convex, cylindrical as well as plano. |
|
Is the shape of the lens round only? |
|
|
We can fabricate with flange or in odd shape as you wish. Please consult. |

| FILTER Q&A |
|
What is the maximum size? |
|
|
It is approximately 300mm squares with about 10mm thickness. It varies by the glass. Please consult with us. |
|
What is the minimum size? |
|
|
It is about 5mm in diameter with 0.5mm thickness. |
|
Who melts the glass? |
|
|
We melt our own glass using our original ingredients that have been developed by our team of engineers. |
|
Can you apply coating to it? |
|
|
Yes, we can.. For surface protection MAR (anti-reflection coating) is usually applied. |
|
What types of the coatings are available? |
|
|
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. |
|
Can you supply a filter that is not listed in the catalog. |
|
|
We melt the glass for our filters. Please consult your requirements with us. |
|
How different is it from the filters made with multilayer coatings? |
|
|
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. |
|
Is it an absorption filter or a reflective type? |
|
|
It is an absorption type filter. We can combine the absorption type filter with the reflective type. |
