Sperian, the worldwide leader in laser eyewear technology, has extended its line of Crystal Clarity ™ laser safety filters that provide exceptional visual acuity. These dielectrically coated filters provide protection over a 30 degree angle of incidence in accordance with domestic and international laser eyewear standards (ANSI 136.1 and EN 207). Unlike other coated filters however, these are stable at all temperatures levels and are 100% tested for optical density and pinholes. They also happen to be the lightest weight coated filter in the industry!
Filter 42, provides an EN 207 DIR L5 from 925-1060nm and DIR L6 at 1064nm. This crystal clear lens has a 92% visible light transmission ( VLT), basically as clear as a window, thus allowing you to easily see and distinguish all the colours of the spectrum. Just as importantly, it provides crystal clear optics.
Filter 40 provides excellent vision with a 72% visible light transmission and is suitable for use with most medical laser systems, offering protection at 755-810nm and 950nm through the infrared up to 10600nm.
