Black Formula Polymer for Backside Reflection Hiding

Transparent substrates introduce challenges in optical metrology, interferometry, and microscopy. Backside reflections reduce signal to noise, are recorded as artifacts, or introduce false signals. These reflections often need to be suppressed, however many uses require the use of a removeable anti-reflection (AR) coatings. Our customer's know Photonic Cleaning Technologies has created several specialized polymer formulations, so it was no surprise when we were asked if we could develop a polymer to hide backside reflections while still providing the ability to clean the substrate to the molecular level. Our Black First Contact fills that requirement! The polymer is already successfully deployed with several companies and is available for purchase in kit and bulk bottle form. The polymer is slightly more viscous than our other non-spray polymers and the dry film will not look smooth like car paint and was never intended to do so, however the polymer on the substrate surface will be smooth to hide reflections. If the bubbles don't allow for a continuous black film apply a second coat to the substrate.
