Super Cold Filters from Asahi Spectra are heat-reflecting filters that are much more efficient than conventional heat-absorbing filters. This means that the substrate (quartz glass) is not damaged even with a high-power light source. Overview of the standard Super Cold Filter products Round with a diameter of 25mm square 50x50mm Customized filters with different specifications […]
Long-pass filters are usually used to isolate areas of a broad spectrum. The purpose of this type of filter is to allow wavelengths above the specified cut-off wavelength to pass and to block wavelengths below the cut-off wavelength. Long-pass filters can provide the desired individual wavelength range in combination with a corresponding short-pass filter. Asahi […]
Neutral density filters are reflective ND filters that are used to diffuse light intensity. The coated chrome film reduces the light by mainly reflecting and partially absorbing it. Asahi’s ND filters are designed to provide uniform spectral performance, particularly in the VIS range, without changing the relative spectral distribution of energy. Nevertheless, they are available […]
Short-pass filters are generally used to isolate areas of a broad spectrum. The task of this type of filter is to allow wavelengths below the output cut-off wavelength to pass and to block wavelengths above the cut-off wavelength. Short-pass filters can provide the desired wavelength range in combination with a corresponding long-pass filter. Asahi Spectra […]
Bandpass filters are typically used to pass a well-defined wavelength band of the spectrum while suppressing both the long and short wavelength sides of the transmission band. Our coating designs are based on multiple cavity resonators. As a result, our bandpass filters have very steep slopes and very high attenuation outside the narrow 10 nm […]
