Anti-Reflective

These screws are suitable for use in optical equipment due to their extremely low spectral reflectance achieved through special surface treatments.
Low-temperature black chrome treatment and stainless steel black have extremely low spectral reflectance, making them ideal for optical equipment requiring anti-reflection properties.
