Advanced Photorejuvenation Strategy! How to choose a better filter? The wind of photon rejuvenation is really great, especially some controversies about the concepts of filter
UHC astronomical observation filter UHC (Ultra High Contrast) ultrahigh Contrast nebula filter is a broadband filter in the astronomical filter series, which has an obvious
Narrow band filter special – 0.2 nm narrow band In the near-infrared band, 1.064 μ M is a commonly used laser wavelength, and its corresponding
2nm bandwidth ultra narrow band filter We have successfully developed an ultra narrow band filter with a bandwidth of 2nm. The central wavelength can cover
Optical Filter products are mainly classified according to spectral band, spectral characteristics, film materials, application characteristics, etc. Spectral band: ultraviolet filter, visible filter, infrared filter
A “filter” is an optical component that filters out light with no wavelength, or selectively transmits light with a specific wavelength. With filters, we can
In the near-infrared band, 1064 μM is a commonly used laser wavelength, and its corresponding lasers and detectors are relatively mature, which is widely used
The camera lens assembly consists of a very important component, that is, a filter; IR cut filter, namely, the infrared cut-off filter, is placed between
Filter is an optical device used to select the required radiation wave band. A common feature of filters is that no filter can make the
The off-axis parabolic mirror is a mirror that does not contain a part of the axis of symmetry from the rotationally symmetric parabolic mirror. Because
