High-transmitting bandpass filters
From AndoverAndover 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 highquality materials and methods as our standard bandpass filters, thus providing a highly stable, long-lasting filter.
- Minimum transmission as high as 80%
- Wavelengths from 438 to 1500 nm
- Sealed and stabilized for longevity
