HF-1 Holmium Glass Filter

The HF-1 Holmium Glass Filter is a high-precision optical filter designed for testing wavelength accuracy in the UV/Vis range. Made from high-quality holmium glass, it provides reliable and consistent reference points for calibrating spectrophotometers and other optical instruments. The filter features sharp, well-defined absorption peaks, enabling accurate wavelength validation across a broad spectral range. Ideal for use in laboratories validation of their spectrophotometers, the HF-1 ensures accuracy in wavelength determination, helping to maintain the integrity of analytical testing.
