Blue & Green Bandpass

Hoya Blue and Green Bandpass Filters are designed to selectively transmit blue and green wavelengths while blocking others. These filters are typically used in applications requiring precise spectral passbands such as fluorescence microscopy, photometric analysis, and color separation in imaging applications. We provide these filters in various sizes and shapes, including square and circular formats, with specific blue-green spectral characteristics that meet a wide range of optical requirements. They are uncoated and utilize the inherent coloration of the glass substrate to achieve the desired filtering effect.
