For instance, it will not be peeled off even if the light source temperature is more than 500 degrees C caused by, say, a malfunctioning cooling fan. In addition, its surface strength is sufficient that a common organic solvent can be used to remove surface dirt. Aperture size can be from 50mm up to 540mm diameter. Application We design and create a reflective mirror effective from the visible to the UV. The UV reflective type mirror is used for a UV cure light source and for a UV radiation light source of stepper machines. Uniformity of coated surface of 535mm diameter reflective mirror, measured at AOI 45 degrees. Copyright(C) 2004 Optical Coatings Japan All Rights Reserved. : : info@ocj.co.jp
