SCHOTT / ZEISS optical glass
Large 5x12mm contact surface, made of precisely polished high-end special glass LaSF.
Filter 589nm
For monochromatic illumination with 589nm wavelength. Without green because of narrow 15nm bandwidth.
Contact liquid nD 1.79
New formula of reduced toxicity, no cristallization and high transparency.
