Prior Scientific Inc.'s new line of illumination systems for microscopy and other optical applications includes two illuminators and a ringlight. The CL20, a 20-W fiber optic illuminator, provides a fixed-color temperature of 3100 K via a single or bifurcated 18-in. flexible lightguide. The 150-W CL150 fiber optic illuminator has a color temperature of 3250 K. The S2041 spot illuminator outputs 10 W with variable intensity control for even illumination across the field of view. The fluorescent ringlight provides 360° of shadow-free illumination and can be fitted to most stereo- and stereozoom microscopes.
