●Product Description
Our NarrowbandFilters pass a narrow spectral band of UV, visible, or NIR radiation and reject out-of-band wavelengths from the X-ray to the far IR. Applications include spectral radiometry, medical diagnostics, chemical analysis, colorimetry, astronomy, and wherever spectral isolation is required.
●Product Detail
Giai Bandpass Filters are manufactured using methods and materials designed to deliver the highest spectral performance
Bandpass filters transmit light only within a defined spectral band ranging from less than one to many nanometers wide. They are used in a wide variety of applications where spectral isolation is required. Bandpass filters are preferable to monochromators because of their higher transmission and better signal-to-noise.
