Frequently Asked Questions (FAQ)
Q
What is the typical average transmittance of these Longpass Filters?
Our stocked Longpass Filters (LPF series) feature a high transmission band transmittance of greater than 85% average, ensuring optimal light throughput in the designated transmission range.
Q
What does the "Cut-off depth >OD4" parameter indicate?
An optical density (OD) depth of greater than 4 means that the filter blocks unwanted shorter wavelengths extremely effectively, allowing less than 0.01% of the out-of-band light to pass through.
Q
How do I identify the cut-off wavelength from the product name?
The number in the product name generally indicates the transition or cut-off wavelength region. For example, LPF800 blocks wavelengths from 400nm to 770nm and starts transmitting efficiently from 825nm up to 1200nm.
Q
Can I request a custom filter if my required wavelength is not in the stock list?
Yes, absolutely. If your application requires specific cut-off ranges, transmission bands, or dimensions not shown in our stock list, please contact us directly using the inquiry link.
Q
Are the spectrogram data and curves available for these filters?
Yes, each item in the product table includes a spectrogram link/image showing the detailed transmission and cut-off curves to help you verify performance for your optical setup.
