Calibration Filters

Hoya Calibration Filters are designed to provide precise wavelength calibration across various optical systems. Products like the Hoya V30 and HY1 filters contain elements such as neodymium and holmium, known for their distinct absorption lines at specific wavelengths. These filters are essential for ensuring the accuracy and performance of devices like spectrophotometers and are used in quality control processes across scientific fields. We offer these multiband calibration filters for applications demanding high precision in wavelength determination and verification.
