HIGH TRANSMITTING BANDPASS FILTERS
Andover now offers a high-transmittance variant of its standard bandpass filter selection. By tailoring the blocking range to match the detector, we can provide maximum possible throughput while maintaining good blocking to meet the customer’s needs. Wavelengths include all popular laser, mercury biomedical and analytical spectral lines.
All filters are constructed using the same high- quality materials and methods as our standard bandpass filters, thus providing a highly stable, long-lasting filter.
These bandpass filters are designed for use in situations where far-infrared blocking is not required. They feature high transmission in the passband region and good blocking over a limited range. Theoretical transmission curves available on request.
For even higher performance, please see our extensive selection of hard-coated bandpass filters.
