hi:
Please check it out whether it is in your reach. Thank you.
Table below shows ideal performance of linear variable Neutral Density filter met our needs:
|
Center wavelength |
Attenuation range |
Dimension |
|
1550nm |
From 0 dB to 40dB |
15mm(length)*3mm(width)*2mm(thickness) |
Notes:
1, The attenuation range could be changed to “from 0 dB to 20dB” if have to.
2, If we have to change the dimension item in upper table, please notice this:
|
The length |
will be no more than |
20mm |
|
The width |
5mm | |
|
The thickness |
2mm |
3, We don’t care about the resolution now. It could be discussed in future.
4, Upper-surface,15mm*3mm, is film coated.
If any question, contact me with email address below. Thank you.
求:线性渐变中性密度滤光片，要中心波长1550nm的，其他看上面的帖，我就不一一翻译了。
只要是您在光电行业并且愿意，都可以和我联系，大家可以交个朋友。
