Revision SF-2 Eyewear Basic Laser Kit, CALI-C Lens, Black Frame, Medium Size, Berry Compliant Revision's CALI-C laser protective eyewear system uses the CALI lens, providing precision laser protection from common hand-held laser threats - green, blue-violet, and near-infrared - without washing out similar colors used on cockpit glass displays. It also transmits plenty of visible light, so aviators don't feel like they are wearing sunglasses during nighttime operations. Revision's CALI-C lens provides 59% photopic and 32% scotopic visible light transmission (VLT), which is the equivalent of a light tint that won't significantly reduce pilot situational awareness. In addition to the light transmitting features of the CALI-C lens itself, Revision adds an anti-reflective coating and an anti-fog coating to the Aviator SF-2 system. The anti-reflective coating is used on the outside of the lens to reduce unwanted reflections which are especially noticeable in a cockpit environment. This coating also helps to maximize VLT and increase cockpit indicator light recognition. And, the anti-fog coating on the inside of the lens gives aviators one less thing to worry about in enclosed, humid environments. OEM: 4-0496-9001, 404969001
