Spherical Mercury Lamp The Spherical Mercury Lamp is a compact, high luminance point light source. When lit and stabilized, it can emit very strong UV and visible spectra. As a UV point source worked in fluorescence microscopy, direct recording oscillometer, and other machines. Currently widely used in medicine, biology, dyeing and printing aging and semiconductor photography, scientific field. Spherical dysprosium Lamp The Spherical dysprosium Lamp is a kind of special metal halide lamp, has the advantages of small point light source, light efficiency, daytime color ( color temperature 6000K ), small size etc. It is ideal light source in the field like: Photographic plate making in print, photocopy, film, TV, stage, hall and other projector light.
