Used as an equivalent of major brand similar material, HK9L is a cheaper option with good optical properties. HK9L is composed of elementary material found in most of optical components. At Sinoptix, we frequently use it as competitive alternative (Bk7) for optical components.
HK9L is high quality optical glasses that is used whenever the additional benefits of fused silica and fused quartz (like for example for high transmission outputs in the UV-C light section and deep IR-light) are not required. This material performs well in all chemical tests and no special handling is required. The material is also relatively hard with an extremely low bubble and inclusion content. Besides it provides an excellent transmittance through-out the visible and near infrared spectra and down to 350 nm in the ultraviolet with low absorption.
