Original Press Release:
Rod Lenses Deliver Uniform UV Cures for Optical Coatings
Fitted with a rod lens assembly, the high intensity BlueWave(TM) 200 Watt UV spot/wand light from DYMAX Corporation, provides uniform illumination for curing adhesives and coatings from .75 x .75 up to 5 x 5 square inches. Uniform curing of adhesives in highly sensitive optical applications eliminates or minimizes movement of critically aligned parts and imperfections in optical coatings due to uneven intensity.
With initial intensity output of 20 W/cm² of UVA (320-390 nm), 15 W/cm² visible (395-445 nm), and 4.5 W/cm² UVB (280-320 nm), the BlueWave(TM) 200 has sufficient intensity to cure adhesives and coatings through rod lens assemblies. The uniform squares of light range in intensity depending on the distance between the end of the lens and the surface of the coating.
Two size rod lenses are available for cures of different sized areas. Rod lens #38699 cures adhesive or coating areas from 3/4" square at 1500 mW/cm² to 2" square at 115 mW/cm². Rod lens #38698 cures adhesive or coating areas from 2" square at 125 mW/cm² to 5" square at 32 m/W/cm².
Using a single pole light guide with no rod lens attachment, efficient curing can easily be accomplished from one to two inches away, however, these circles of light do not provide uniform cures. Fitted with the rod lenses the light is dispersed in a uniform square pattern.
