The q factor of a narrowband filter is always

Webb29 feb. 2024 · Very long exposure times are often used with narrowband filters. Several hours spent imaging each color is not uncommon. Typical individual exposures might be in the range of 10-20 minutes, with 5 or 6 exposures of that duration taken in each filter. Spending a whole night imaging one or two objects is typical. Webb1 juli 2024 · According to the results, by changing geometric factors of the packaging and the applied force to the device, it is possible to design filters that have even better thermal stability. Conclusion. The thermal response of the filter was evaluated from 0 to 70°C. The filter features spectral short offset for such temperature variation.
