If you cannot find the information you need in the following section, feel free to contact us. We will reply as soon as possible.
- Q1: How do I order customized optical filters?
- A1: Ordering customized optical filters can be done using our online ordering form. We will reply in a business day by email, fax, or phone.
- Q2: I would like to use filters under high temperatures.
- A2: Generally our MC Narrow Band pass filters can work under 158F (70C) but total performance of most filters weakens under high temperature. It is difficult to define whether the condition is perfectly safe or not. Therefore it is important to protect them with anti-heat components (ex: our Super Cold Filters or cooling fans). For more information, feel free to contact us.
- Q3: Do your filters deteriorate under strong UV rays?
- A3: UV rays harm especially the filter units' glue. How it affects depends on the time of ray casting or ray strength. Please contact us for we have various alternatives to solve this problem such as filter units without glue or anti-UV filter units.
- Q4: The spectral performance I measured is lower than the attached data provided by Asahi Spectra.
- A4: First, please confirm that the filter is set at the right angels against the light. All filter data are measured under the condition where our filters are used at the specified angles. Bandpass filters are made of dielectric multi-layer thin films where spectral properties tend to shift to shorter wave region, causing transmittance average rates to go down if the incident angle is leaned.
- Q5: Do you accept credit cards?
- A5: Yes. We accept VISA, Master Card and American Express.
